Describe the basic characteristics that define an independent-measures, or a between-subjects, research study.

To describe: The basic characteristics that define an independent-measures, or a between-subjects, research study.
Answer to Problem 1P
It uses a separate sample for each of the treatments or populations being compared
Explanation of Solution
An independent measures design is the one in which different participants are used in each condition of the independent variable. Different participants are used for the two groups i.e. every participant is only subjected to a single treatment.
Since independent measure design uses two distinct populations (and population means), hence, each of these have their own sample mean and variances.

- mean trough level of the population to be 3.7 micrograms/mL. The researcher conducts a study among 93 newly diagnosed arthritis patients and finds the mean trough to be 4.1 micrograms/mL with a standard deviation of 2.4 micrograms/mL. The researcher wants to test at the 5% level of significance if the trough is different than previously reported or not. Z statistics will be used. Complete Step 5 of hypothesis testing: Conclusion. State whether or not you would reject the null hypothesis and why. Also interpret what this means (i.e. is the mean trough different from 3.7 or noarrow_forward30% of all college students major in STEM (Science, Technology, Engineering, and Math).
