Briefly describe what skewness and kurtosis tell you about these data with regard to normality.

Assignment Question

Descriptive statistics are just what they sound like, statistics that allow you to describe or summarize the data with regard to such things as their distribution and their spread. Descriptive statistics provide you with a picture of your data while inferential statistics (which we will discuss in subsequent assessments) allow you to draw conclusions about relationships between variables or differences between groups. A solid understanding of descriptive statistics is foundational to grasping the concepts presented in inferential statistics. This assessment measures your understanding of key elements of descriptive statistics.

Your first statistical software assessment 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.

SECTION 1: 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.

SECTION2: 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.
