Description
- Respond to the following in a minimum of 175 words, the word count is critical to the work:
We’ve now covered descriptive statistics and an introduction to inferential statistics with discussions about hypothesis testing. Now it’s time to learn a few of the types of tests we can use to test hypotheses. It’s important to keep in mind that this material builds on itself, but it isn’t redundant. Each type of statistical analysis is unique and addressed a specific analytic need.
This week we are learning about z-tests and t-tests.
1) How are these two tests similar and different?
2) What are confidence intervals?
3) Provide an example (make it as personalized as you’d like) of a research scenario that could utilize an independent samples t-test.
- Research in the University Library to find three (3) empirical (those containing data) research articles using one of the analytic methods studied this week (i.e., z test, independent sample t test, repeated measures t test).
