Step 1: Write Section 1 of the DAA:The Data Analysis Plan Name the variables used in this analysis and whether they are categorical or continuous.

Step 1: Write Section 1 of the DAA:The Data Analysis Plan

Name the variables used in this analysis and whether they are categorical or continuous.
State a research question, null hypothesis, and alternate hypothesis for the independent samples t-test.

Step 2: Write Section 2 of the DAA:Testing Assumptions

Test for one of the assumptions ofttests - equality (homogeneity) of variances.

Create statistical output showing the Levene's Test for Equality Variances.
Paste the table in the DAA template.
Interpret the Levene's test.

Step 3: Write Section 3 of the DAA:Results and Interpretation

If the homogeneity assumption is not violated (Section 2), run the "Student" version of the independent samplesttest in the statistical software.
If the homogeneity assumption is violated, run the "Welch" version of the independent samples t-test in the statistical software.
Also, run the "Descriptives" option to obtain the means and standard deviations for each group.

Paste the statistical software output of thettest into the DAA template. Below the output:

Report the means and standard deviations for each group.
State the results of thettest.
Interpret the statistical results against the null hypothesis and state whether it is rejected or not rejected.

Step 4: Write Section 4 of the DAA:Statistical Conclusions

Provide a brief summary of your analysis and the conclusions drawn about thisttest.
Analyze the limitations of the statistical test and/or possible alternative explanations for your results.

Step 5: Write Section 5 of the DAA:Application

Analyze how you might use the independent samplesttest in your field of study.
