Summary of Dataset

There are a total of 21 variables in the dataset ‘grades.sav,’ which contain information on 105 subjects. Of these variables, there are seven nominal variables (i.e., information about categories of some subjects, such as name, last name, and gender). In addition, the data set contains ten numeric and continuous scale variables like quiz and final scores. In addition, there are four ordinal variables such as “lowup” and “passfail” that denote the order or ranking of a category.

The dataset focuses on the academic performance of the subjects, especially their GPA scores. Calculations of descriptive statistics using SPSS show that the mean GPA of the 105 subjects is 2.7789, and the standard deviation is 0.76380. This means that the GPA scores show some varying levels across the sample. Additionally, the range of the GPAs was 2.86, which shows a large gap between the highest and lowest GPA scores shown in the data set.

Please write a short paragraph (APA style) which includes a brief description of the dataset (variables included in the dataset), the number of subjects, and the mean and standard deviation of the dataset.

Length: There is not a set number of pages required for this assignment. All questions in the assignment need to be answered.  In addition to the answers to the assignment questions, also submit the output (.spv) file.

(Note. SPSS automatically generates the .spv file as you work in SPSS. When you close your SPSS main window, SPSS will ask you if you want to save the output file. Click ‘yes’, then save to your computer and upload with your assignment.)
