Using SPSS – You will do assumption testing, descriptive statistics, etc as indicated for the two “research questions” presented.   
Compare race and military (chi-square)   
Compare pre and post test (paired sample t test)
 Using the data set, determine the measurement level of data of the dependent or outcome variable (Psychological Stress Score) you are analyzing.
Is the data categorical, ordinal, or interval or ratio?
Before performing any statistical tests, you must determine which tests would be most appropriate for your data type.
First, perform a pre-evaluation of the data for outliers (all variables) and normal distribution (only dependent variables).
Perform and interpret an appropriate series of statistical tests (including pre-analytical testing for outliers and normal distribution of data) that answer the following research question:
How would you quantitatively describe the study population?  Summarize the primary demographic data using descriptive statistics.
Is there any association between gender and race in this military study?
Perform an appropriate chi-square analysis.  Perform preliminary assessment of the data, then compare pretest to post-test scores.
In the total population being studied, what was the effect of the yoga intervention on stress?
Provide the SPSS “.sav” output file that shows your programming and results for this assignment.
Summarize the clinical implications related to the statistical outcomes for each of the questions above.
Describe potential limitations of the study
