H7864-2 Descriptive Statistics
TOPIC: Descriptive Statistics
Your first IBM SPSS assignment includes two sections in which you will do the following:
· Create two histograms.
· Calculate measures of central tendency and dispersion.
·
· As you work on this assignment, you may find the Data Set Instructions [DOCX] helpful.
· Provide a title for your document
The grades.sav file is a sample SPSS data set. The data represent a teacher's recording of student demographics and performance on quizzes and a final exam. you will create and describe two histograms and a descriptives table using these data.
Part 1
Create two histograms for visual interpretation using the following variables:
|
|
|
|
SPSS Variable |
Definition |
|
Lowup |
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 nature of the curves.
Part 2
Create a descriptives table to assess measures of central tendency and dispersion using the following variables:
|
|
|
|
SPSS 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 assignment as an attached Word document.
Competencies Measured
By successfully completing this assignment, you will demonstrate your proficiency in the following course competencies and assignment criteria:
· Competency 1: Analyze the computation, application, strengths, and limitations of various statistical tests.
