# ANCOVA Analysis Assignment

A recent study of student anxiety suggested that test anxiety interfered with the effects of studying skills on student test performance. Students were classified as high or low in test anxiety based on responses to an anxiety inventory, then classified as high or low in study skills based on responses to a study skill scale. An overall measure of test performance was obtained by averaging the number of scores of three tests the students completed over the course of a semester. Enter the following data into SPSS and use anANCOVA to analyze the results.

MANOVA Analysis

Researchers are interested in the effects of cognitive behavior therapy and behavior therapy on Obsessive Compulsive Disorder. We could compare a group of OCD sufferers after CBT and after behavior therapy with a group of OCD sufferers who are still awaiting treatment (a no treatment condition).

As OCD has both cognitive and behavioral elements, it is not enough to look only at therapy’s influence on behavioral outcomes. Therefore, our study used two dependent measures: the occurrence of obsession-related behaviors (Actions) and the occurrence of obsession-related cognitions (Thoughts).

The dependent variables were measured on a single day and so represent the number of obsession-related behaviors/thoughts in a normal day. Use data set OCD.sav.

1. What is/are our research question(s)?

2. Prescreen the data. a. Does our data meet all the assumptions for a MANOVA?

b. Does the data need to be corrected for outliers and normality? (Copy and paste in to this section the information that helped you reach your conclusion).

c. Does the data demonstrate homogeneity of variance-covariance? (Copy and paste in to this section the information that helped you reach your conclusion).

3. “Run” the MANOVA analysis (i.e., use the printout of SPSS output). a. Which MANOVA test statistic should you use? Why?

4. Using the appropriate group multivariate statistics and ANOVA/post hoc tests, report your results.  Get Maths homework help today

I wish the writer would have picked a more natural topic. Although the work is good, it is obvious that the writer of the material is African American. The fact that I am not African American raises questions.
