Perform a t-test and identify several elements of the research study and analysis results. (Using Jasp)

• Download the class data file:  Independent T data.csv 
• Open the file with JASP.
• Select T-Tests, then Independent- samples t-test.
• Under Tests, select Students and Welch
• Move the independent variable into the Grouping Variable box, and the dependent variable into the Test Variable box.
• Under Assumptions Checks select Equality of Variances
  • To determine which t value and df to report you must first check the significance of the Levene's test for homogeneity of variance.  If the p value from this test is less than .05 you should report values from the bottom row of the t table (Welch test).  Otherwise report values for the top row (Student test).
    
    
• Select Descriptives and Descriptives Plots
• Under Additional Statistics, select Location Parameter, Effect Size.
  
• The output provided includes the results of your t-test analysis.
