__RSCH 6210 Quantitative Reasoning and Analysis__

**(Except Week 2 Assignment)**

**RSCH 6210 Week 1 Discussion Latest-Walden**

__The Logic of Inference: The Science of Uncertainty__

Describing and explaining social phenomena is a complex task. Box’s quote speaks to the point that it is a near impossible undertaking to fully explain such systems—physical or social—using a set of models. Yet even though these models contain some error, the models nevertheless assist with illuminating how the world works and advancing social change.

The competent quantitative researcher understands the balance between making statements related to theoretical understanding of relationships and recognizing that our social systems are of such complexity that we will always have some error. The key, for the rigorous researcher, is recognizing and mitigating the error as much as possible.

As a graduate student and consumer of research, you must recognize the error that might be present within your research and the research of others.

To prepare for this Discussion:

Use the Walden Library Course Guide and Assignment Help found in this week’s Learning Resources to search for and select a quantitative article that interests you and that has social change implications.

As you read the article, reflect on George Box’s quote in the introduction for this Discussion.

For additional support, review the Skill Builder: Independent and Dependent Variables, which you can find by navigating back to your Blackboard Course Home Page. From there, locate the Skill Builder link in the left navigation pane.

__By Day 3__

Post a very brief description (1–3 sentences) of the article you found and address the following:

Describe how you think the research in the article is useful (e.g., what population is it helping? What problem is it solving?).

Using Y=f(X) +E notation, identify the independent and dependent variables.

How might the research models presented be wrong? What types of error might be present in the reported research?

Be sure to support your Main Post and Response Post with reference to the week’s Learning Resources and other scholarly evidence in APA Style.

__By Day 5__

Remembering that all research has some error, respond to at least one colleague’s post and comment on how we as social change agents and critical consumers of research can balance the usefulness with the error in the research. Do we throw the research out because of too much error, or is there something useful that it can tell us?

**RSCH 6210 Week 2 Discussion Latest-Walden**

__Displaying Data__

Visual displays of data provide you and anyone else with a graphical display of what is often a complex array of quantitative data. A key strength of visualization is the ability to quickly enlighten you with key data. Rather than solely relying on your audience to interpret numerical values and statistics explained in a narrative, a visual display can easily illustrate descriptions, relationships, and trends. Although the focus is on simplicity, the researcher has an obligation to present these graphical displays in a clear and meaningful way.

For this Discussion, you will explore ways to appropriately display data.

To prepare for this Discussion:

Review the Learning Resources for this week related to frequency distributions and graphic displays of data.

Using the SPSS software, open the General Social Survey dataset found in this week’s Learning Resources.

Next, create a figure or table from a few selected variables within the dataset.

Finally, think about what is good about how the data are displayed in the figure or table you created and what is not so good.

__By Day 3__

Post your display of the table or figure you created and provide an explanation of why this would be the best way to display the data provided.

Be sure to support your Main Post and Response Post with reference to the week’s Learning Resources and other scholarly evidence in APA Style.

__By Day 5__

Respond to at least one of your colleagues’ post and determine whether you are able to understand the “whole picture” of the data or understand the data in its entirety. What might you add to their display and why? What might you change to their display and why?

**RSCH 6210 Week 3 Discussion Latest-Walden**

__Central Tendency and Variability__

Understanding descriptive statistics and their variability is a fundamental aspect of statistical analysis. On their own, descriptive statistics tell us how frequently an observation occurs, what is considered “average”, and how far data in our sample deviate from being “average.” With descriptive statistics, we are able to provide a summary of characteristics from both large and small datasets. In addition to the valuable information they provide on their own, measures of central tendency and variability become important components in many of the statistical tests that we will cover. Therefore, we can think about central tendency and variability as the cornerstone to the quantitative structure we are building.

For this Discussion, you will examine central tendency and variability based on two separate variables. You will also explore the implications for positive social change based on the results of the data.

To prepare for this Discussion:

Review this week’s Learning Resources and the Descriptive Statistics media program.

For additional support, review the Skill Builder: Visual Displays for Categorical Variables and the Skill Builder: Visual Displays for Continuous Variables, which you can find by navigating back to your Blackboard Course Home Page. From there, locate the Skill Builder link in the left navigation pane.

Review the Chapter 4 of the Wagner text and the examples in the SPSS software related to central tendency and variability.

From the General Social Survey dataset found in this week’s Learning Resources, use the SPSS software and choose one continuous and one categorical variable Note: this dataset will be different from your Assignment dataset).

As you review, consider the implications for positive social change based on the results of your data.

__By Day 3__

Post, present, and report a descriptive analysis for your variables, specifically noting the following:

For your continuous variable:

Report the mean, median, and mode.

What might be the better measure for central tendency? (i.e., mean, median, or mode) and why?

Report the standard deviation.

How variable are the data?

How would you describe this data?

What sort of research question would this variable help answer that might inform social change?

Post the following information for your categorical variable:

A frequency distribution.

An appropriate measure of variation.

How variable are the data?

How would you describe this data?

What sort of research question would this variable help answer that might inform social change?

Be sure to support your Main Post and Response Post with reference to the week’s Learning Resources and other scholarly evidence in APA Style.

__By Day 5__

Respond to at least one colleagues’ post with a comment on the presentation and interpretation of their analysis. In your response, address the following questions:

Was the presentation of results clear? If so, provide some specific comments on why. If not, provide constructive suggestions.

Are you able to understand how the results might relate back to positive social change? Do you think there are other aspects of positive social change related to the results?

**RSCH 6210 Week 4 Discussion Latest-Walden**

__The Importance of Relationships__

As its name implies, confidence intervals provide a range of values, along with a level of confidence, to serve as an estimate of some unknown population value. Since it is rare to have access to the entire population, you must frequently rely on the confidence interval of the sample to make some inference about the population of interest. Before making accurate inferences to the population, we need to fully understand how the three key components of the interval—variability in the data, sample size, and confidence level—impact the width of the interval.

For this Discussion, you will explore the relationship between these components and understand the trade-off between reducing risk in our confidence of estimates and increasing precision.

To prepare for this Discussion:

Review Chapters 7 and 8 of the Frankfort-Nachmias & Leon-Guerrero text and in Chapter 8, p. 256, consider the 2012 Benghazi Terrorist Attack Investigation and focus on how different levels of confidence and sample size work together.

Review Magnusson’s web blog found in the Learning Resources to further your visualization and understanding of confidence intervals.

Use the Course Guide and Assignment Help found in this week’s Learning Resources to search for a quantitative article related to confidence intervals.

Using the SPSS software, General Social Survey dataset and choose a quantitative variable that interests you.

__By Day 3__

Using SPSS:

Take a random sample of 100.

Calculate the 95% confidence interval for the variable.

Calculate a 90% confidence interval.

Take another random sample of 400.

Calculate the 95% confidence interval for the variable.

Calculate a 90% confidence interval.

Post your results and an explanation of how different levels of confidence and sample size affect the width of the confidence interval. Next, consider the statement, “Confidence intervals are underutilized” and explain what the implications might be of using or not using confidence intervals. Provide examples based on the results of your data. Also, use your research to support your findings.

__By Day 5__

Respond to one of your colleague’s posts and explain how you might see the implications differently.

**RSCH 6210 Week 5 Discussion Latest-Walden**

__Statistical Significance and Meaningfulness__

Once you start to understand how exciting the world of statistics can be, it is tempting to fall into the trap of chasing statistical significance. That is, you may be tempted always to look for relationships that are statistically significant and believe they are valuable solely because of their significance. Although statistical hypothesis testing does help you evaluate claims, it is important to understand the limitations of statistical significance and to interpret the results within the context of the research and its pragmatic, “real world” application.

As a scholar-practitioner, it is important for you to understand that just because a hypothesis test indicates a relationship exists between an intervention and an outcome, there is a difference between groups, or there is a correlation between two constructs, it does not always provide a default measure for its importance. Although relationships are significant, they can be very minute relationships, very small differences, or very weak correlations. In the end, we need to ask whether the relationships or differences observed are large enough that we should make some practical change in policy or practice.

For this Discussion, you will explore statistical significance and meaningfulness.

To prepare for this Discussion:

Review the Learning Resources related to hypothesis testing, meaningfulness, and statistical significance.

Review Magnusson’s web blog found in the Learning Resources to further your visualization and understanding of statistical power and significance testing. Review the American Statistical Association’s press release and consider the misconceptions and misuse of p-values.

Consider the scenario:

A research paper claims a meaningful contribution to the literature based on finding statistically significant relationships between predictor and response variables. In the footnotes, you see the following statement, “given this research was exploratory in nature, traditional levels of significance to reject the null hypotheses were relaxed to the .10 level.”

__By Day 3__

Post your response to the scenario in which you critically evaluate this footnote. As a reader/reviewer, what response would you provide to the authors about this footnote?

__By Day 5__

Respond to at least one of your colleagues’ posts and explain the benefits and consequences of the “relaxed” level of significance.

**RSCH 6210 Week 1 Assignment Latest-Walden**

__Assignment: Variables, Measurement, and SPSS__

Quantitative research consists of testing and understanding relationships between variables. Researchers construct these variables as measureable expressions of social phenomena. Modern statistics provides you with a host of resources to answer questions, but each statistical test has a set of assumptions regarding the measurement of the variables. It is therefore important to understand how variables are measured because their measurement will influence the type of analytic tools available to you.

SPSS is a statistical software program that allows you to enter these variables into a spreadsheet format and record the measurements from a sample. Additionally, SPSS allows you to perform statistical analysis. Before launching into your analyses, though, it is important to understand how the variables are measured. That understanding will help you interpret the SPSS output.

In this week’s Discussion, you considered topics with social change implications. For this Assignment, you will examine data to analyze independent and dependent variables, determine how they are measured, and decipher whether a social change question can be answered and the implications for such change.

To prepare for this Assignment:

Review the Learning Resources as well as the SPSS resources found in this week’s Learning Resources.

Review, download, and install the SPSS software on your computer using the IBM SPSS Version 23 Installation and Registration document for PC or for MAC in this week’s Learning Resources.

Using the SPSS software, open the Afrobarometer dataset or the High School Longitudinal Study dataset (whichever you choose) found in this week’s Learning Resources and then choose two variables that interest you.

For this Assignment:

Write a 1- to 2-page summary and include the following:

A description of what the each of the variables measure.

A description of the unit of analysis.

A description and explanation of the levels of measurement for each variable (i.e., nominal, ordinal, interval, ratio).

Explain how you might conceive these variables to be used to answer a social change question. What might be the implications for social change?

Support your summary using appropriate scholarly citations and references. Use proper APA format.

**RSCH 6210 Week 5 Assignment Latest-Walden**

__Assignment: Evaluating Significance of Findings__

Part of your task as a scholar-practitioner is to act as a critical consumer of research and ask informed questions of published material. Sometimes, claims are made that do not match the results of the analysis. Unfortunately, this is why statistics is sometimes unfairly associated with telling lies. These misalignments might not be solely attributable to statistical nonsense, but also “user error.” One of the greatest areas of user error is within the practice of hypothesis testing and interpreting statistical significance. As you continue to consume research, be sure and read everything with a critical eye and call out statements that do not match the results.

For this Assignment, you will examine statistical significance and meaningfulness based on sample statements.

To prepare for this Assignment:

Review the Week 5 Scenarios found in this week’s Learning Resources and select two of the four scenarios for this Assignment.

For this Assignment:

Critically evaluate the two scenarios you selected based upon the following points:

Critically evaluate the sample size.

Critically evaluate the statements for meaningfulness.

Critically evaluate the statements for statistical significance.

Based on your evaluation, provide an explanation of the implications for social change.

Use proper APA format and citations, and referencing.

You might not become a quantitative researcher nor use statistical methods in your profession, but as a consumer, citizen, and scholar-practitioner, it will be important for you to become a critical consumer of research, which will empower you to read, interpret, and evaluate the strength of claims made in scholarly material and daily news.

For this Assignment, you will critically evaluate a scholarly article related to t tests.

To prepare for this Assignment:

Search for and select a quantitative article specific to your discipline and related to t tests. Help with this task may be found in the Course guide and assignment help linked in this week’s Learning Resources.

For this Assignment:

Write a 2- to 3-page critique of the article. In your critique, include responses to the following:

Why did the authors use this t test?

Do you think it’s the most appropriate choice? Why or why not?

Did the authors display the data?

Do the results stand alone? Why or why not?
