Using the final and lowup variables in your grades.jasp data set, create two histograms and paste them into your Word document:

Variables and Definitions

Variable	Definition
Lowup	lower division =1; Upper division =2
Final	Final exam: number of correct answers

Create:

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

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

Section 2: Calculate Measures of Central Tendency and Dispersion

Using the grades.jasp Download grades.jaspfile, compute descriptive statistics, including mean, standard deviation, skewness, and kurtosis for gpa and quiz3.

Variables and Definitions

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 with regard to normality.

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