Question 1

Measures of variability include the range, the variance, and the standard deviation, and define how far away the data points tend to fall from the center.

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?

Include your own experience as well as 2 citations that align with or contradict your comments as sourced from peer-reviewed academic journals, industry publications, books, and/or other sources. Cite your sources according to APA guidelines. If you found information that contradicts your experience, explain why you agree or disagree with the information.

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

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