Calculate and Interpret Data

This assignment has two parts, which will be submitted in one document.

For this task, you will calculate the mean, median, and mode for a fictitious data set. These data represent the results of a fictitious study, which investigates whether a new drug (Drug A) is more effective than a placebo (i.e., an inactive substance) in the treatment of depression. The researcher is also interested in whether the effects of the drug varies by age so participants between the ages of 18-39 years were recruited (the younger adult group), and participants between the ages of 60-80 years were recruited (the older adult group). Participants were randomly assigned to either the placebo group or to the drug group (Drug A). All participants were first screened to ensure they met the criteria for depression. After 2 months of taking either the placebo or Drug A, participants returned to the lab and completed a measure of depressive symptomology called the Beck Depression Inventory-II (BDI-II).

article evaluation—

Article evaluation (DA & Logistic Regression article evaluation) has the purpose to expose to how to write and reports each statistical technique. The evaluation (2 pages) must covered the following issues:
a. Justification for the use of the technique.
b. Evidence of data screening and assumptions tested.
c. Quality of the results presentation with complete information needed to evaluate the result.
d. Discussion of results supported by the information offered.
e. Suggestions for improving the report.
In the attachment, the DA & Logistic Regression article to be evaluated.

Any topic (writer’s choice)

Using the data on the "National Cancer Institute Data" Excel spreadsheet, calculate the descriptive statistics indicated below for each of the Race/Ethnicity groups. Refer to your textbook and the Topic Materials, as needed, for assistance with creating Excel formulas.

Provide the following descriptive statistics:

Measures of Central Tendency: Mean, Median, and Mode
Measures of Variation: Variance, Standard Deviation, and Range (a formula is not needed for Range).
Once the data is calculated, provide a 150-250 word analysis of the descriptive statistics on the spreadsheet. This should include differences and health outcomes between groups. This assignment uses a rubric. Please review the rubric prior to beginning the assignment to become familiar with the expectations for successful completion.
