Problem of Practice Mock Study Development Template: Week Four
Instructions:
Use SPSS® to check your mock data for the following:
 Assumptions of normality (Shapiro-Wilk)
 Homogeneity of variance (Lavene)
 Outliers
 Skewness/Kurtosis
Complete each of the associated tasks below:
1) Create a series of tables that depict your results. Do not simply paste your output from SPSS®; rather,
prepare each table to demonstrate your ability to format according to APA guidelines.

Skewness/Kurtosis
The data is positively skewed. Tail to the right
Kurtosis is the same for both factors.
4) What steps will you take if your data is not normally distributed?
I can address the normality of the data by
1. Subtracting the mean from the SD
2. Remove the outliers if any exist.
3. Use a logarithm
4. Use the Box-Cox transformations
