Your first statistical software assignment includes two sections in which you will do the following:

• Create two histograms.
• Calculate measures of central tendency and dispersion.

This will give you some experience with the data set.

Key Details and Instructions

• Submit your assignment as a Word document.
• Refer to theJASP Step-by-Step: Histograms and Descriptive Statistics [PDF]document for additional help completing this assignment.
• ViewJASP Speedrun: Descriptive Statistics [Video]Links to an external site for a brief tutorial video on this assignment.
• ViewDeeper Dive Descriptive Statistics [Video]Links to an external site for a longer video interpreting the statistical software output.

As you work on this assignment, refer to the7864 Data Set Instructions [PDF]document for information on variables used in this course.

Download the 7864 data setand grades. jasp, a sample data set, and save it to your computer. This data file is used in all four papers (Week 2, Week 4, Week 6, & Week 8).

Part 1

Create two histograms for visual interpretation using the following variables:

Variable	Definition
Low up	Lower division =1; Upper division =2
Final	Final exam: number of correct answers

Create two histograms and paste them into your Word document:

• A histogram for lower division students.
• A histogram for upper-division students.

Briefly describe what a visual inspection of this output tells you about the shape of the distributions.

Part 2

Create a descriptives table to assess measures of central tendency and dispersion using the following variables:

Variable	Definition
GPA	Previous grade point average
Quiz3	Quiz 3: number of correct answers

Create a descriptives table and paste it into your Word document.

Under the table:

• Report the mean, standard deviation, skewness, and kurtosis for GPA and quiz3.
• Briefly describe what skewness and kurtosis tell you about these data about normality.

Submit both sections of your assignment as an attached Word document.
