GPA is interval level data one can report all measures of central tendency and dispersion (Creswell, 2012). In the original data case 38 had a GPA reported as 9.00. This value is of course impossible and since there were no missing values defined in the data set this case was treated as missing data. If used as reported it would have resulted in a much larger standard deviation and slightly larger mean for the calculations. The mean GPA of the sample was 3.2941. The median GPA was 3.2750 with a mode of 4.00. The standard deviation was .50644 (with the miscoded value the standard deviation would be .82215). The range for GPA in the sample was 2.00 with a minimum value of 2.00 and a maximum value of 4.00 (including the miscoded value would inflate the range to seven).
