RES710 Statistical Research Methods And Design I

Week 1 Discussion

DQ1 Statistics

Write a 250- to 300-word response to the following:

What are the key differences between descriptive and inferential statistics? Offer an example of each and explain when you might use each (descriptive and inferential statistics) in your research study.

DQ2 Research

Write a 250- to 300-word response to the following:

State whether the data you have chosen to work with originated in the GSS site or in the University Library. If a dataset was chosen from the library data, you must state the specific location and dataset you extracted.

Choose and list at least three variables (Hint: choose two independent and one dependent), along with the associated survey question and response choices.

Create a research question using all three of your variables.

Create a null and alternative hypothesis that supports your research question.

Week 2 Discussion

DQ1 Types of Variables and Data

Understanding and applying levels of measurement is an important part of your research.

Using the variables you chose in Week 1, write a 250- to 300-word response to the following:

List the levels of measurement for each of your chosen variables and explain why understanding levels of measurement is important in quantitative research.

DQ2 Understanding What Impact Variable Types Have on Statistical Tests

An important component to quantitative research is choosing the correct statistical test. The University Library offers several Sage Research Methods resources to help you in your endeavors.

Using the “Sage Tools – Which Stats Test?” link from the University Library and your chosen variables, complete the “Which Stats Test?” survey to decide which statistical tests could be most beneficial to understanding the relationship between your variables.

Next, review Figure 9.1. A Quick (but Not Always Great) Approach to Determining What Statistical Test to Use, on p. 201 of Statistics for People Who (Think They) Hate Statistics.

Write a 250- to 300-word response to the following:

Discuss the process of choosing a statistical test using the tools from Sage and your Salkind & Frey (2019) text.

Explain what impact variable types have on statistical tests.

Week 3 Discussion

DQ1 Skewed Distribution

Write a 250- to 300-word response to the following:

What is the difference between a normal distribution and a skewed distribution?

What causes a skew and how might a researcher deal with skewed data?

Under what conditions would it be acceptable to allow skewed variables in a research study?

DQ2 Measures of Central Tendency

Write a 250- to 300-word response to the following:

How will you use measures of central tendency in your dissertation research or professional practice? Cite specific examples of how you expect to apply this week’s topics.

Week 4 Discussion

DQ1 Measures of Variability

Write a 250- to 300-word response to the following:

How do you choose which measure of variability to use and what considerations may have an impact on your decision?

DQ2 Measures of Variation

Measures of variation provide us with information about how a set of scores are distributed. Refer to the data you collected in Week 1 or other dataset practice, running measures of variability for each of your variables.

Write a 250- to 300-word response to the following:

What specific considerations did you use to determine which test to run?

Why are measures of variability important when interpreting your data.

Week 5 Discussion

DQ1 Normal Distribution

In statistics, it is critical to know what is meant by a normal distribution.

Write a 250- to 300-word response to the following:

What are the properties of a normal distribution?

Is a normal distribution always necessary? Why or why not?

Why do researchers often refer to a normal distribution as a theoretical normal distribution?

DQ2 Sampling

In Ch. 6, Frankfort-Nachmias and Leon-Guerrero (2018) explore various aspects related to sampling. Explore the aims of sampling and types of probability sampling. Then refer to your own mock study topic and variables identified in Week 1.

Write a 250- to 300-word response to the following:

What types of sampling do you think would be most appropriate for your study? Why?

How does sample size affect the validity of a study?

Week 6 Discussion

DQ1 Confidence Intervals

When implementing a research study, it is important to know the relationship between confidence intervals, sample sizes, and estimated standard errors.

Write a 250- to 300-word response to the following:

Explain the relationship between confidence intervals, sample sizes, and estimated standard errors.

How might understanding these elements be useful in understanding your mock data used throughout this course?

DQ2 Hypothesis Testing

Refer to the research question and hypotheses you created in Week 1.

Write a 250- to 300-word response to the following:

Discuss each of the 5 steps in hypothesis testing as it relates to your data.

Note: You will only need to explain steps 4 and 5 in general, but steps 1-3 should be fairly specific to your data.

Week 7 Discussion

DQ1 Understanding the Application of Measures of Association and Significance Tests

Last week you completed the hypothesis test application, where you reviewed each of the common statistical tests in detail. Refer to the information from that assignment and the data you have been working with throughout this course.

Write a 250- to 300-word response to the following:

Which statistical test would be most appropriate for your variables? Why?

DQ2 Finding Scholarly Support

Providing scholarly support for your research project is a necessary part of the process. Find two scholarly sources that offer additional insight into your course project/mock study research topic (as defined by the research question and/or hypothesis you’ve been working with throughout this course).

Write a 250- to 300-word response to the following:

Briefly summarize each article and explain why each is relevant to your project.

Week 8 Discussion

DQ1 Assumptions

Frankfort-Nachmias and Leon-Guerrero (2018) explain that “several assumptions are required” in statistical hypothesis testing.

Write a 250- to 300-word response to the following:

Explain what this statement means in your own words.

What assumptions might be present in your dissertation study work?

DQ2 Course Reflection

Throughout this course, you have completed the research process. Take a moment to reflect on your learning.

Write a 250- to 300-word response to the following:

How will you apply what you’ve learned in this course to your personal, professional, or future research work?
