Suggested Exercise
(~5 minutes)

Assume you’re a biomedical researcher analyzing data from an experiment where you want to understand if a new drug affects blood pressure levels in patients with hypertension. Your hypothesis is that patients taking the new drug will show a statistically significant reduction in blood pressure compared to those not taking the drug.

Open StatXFinder and navigate to the decision tree for selecting an appropriate statistical test. You will be comparing the mean blood pressure levels between two independent groups: patients taking the new drug and patients not taking the new drug. Follow the guided questions in StatXFinder to determine the appropriate statistical test for your data.

In order, StatXFinder will walk through a number of data characteristics that you’ll want to consider when choosing the appropriate test for your exercise.

What do you suppose the potential pitfalls of using a tool like this might be? Is this a healthy practice?
