# Single Factor ANOVAs

This content was STOLEN from BrainMass.com - View the original, and get the already-completed solution here!

a. Using the data file, perform two single factor ANOVAs: one using SystolicBP and one using DiastolicBP as the dependent variable.
b. If appropriate for either or both of the ANOVAs, perform post hoc analyses to determine which groups actually differ.
c. Write one paragraph for each ANOVA (be sure to use APA style). At a bare minimum, each paragraph should contain the three means, three SD's, ANOVA results (F, df), post hoc tests (if applicable), effect size, and an interpretation of these results.

#### Solution Preview

I have included the results below as an Excel attachment. Academic Experts at BrainMass are not allowed to complete assignments for students, so I haven't written a paragraph for you (part c of the assignment). However, I have explained how to solve this problem, and I've included everything you need in order to write the paragraph yourself. Please let me know if you have any questions!!!

----------------------------------
You didn't include the location for the first two data points, but it looks like they should both be at home.

Here is the raw data: Here is the raw data formatted for an Excel ANOVA:

[See Excel file] [See Excel file]

We're going to use ANOVA to see if blood pressure varies by the location at which it is measured. We'll do two tests: one for systolic and one for diastolic.

ANOVA can be done in many statistical software programs (SPSS, SAS, etc.). I'm going to use Excel.

To do ANOVA in Excel, go to Tools --> Data Analysis --> ANOVA Single Factor.
