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 the JASP Step-by-Step: Histograms and Descriptive Statistics [PDF] document for additional help in completing this assignment.
- View JASP Speedrun: Descriptive Statistics [Video]Links to an external site. for a brief tutorial video on this assignment.
- View Deeper Dive Descriptive Statistics [Video]Links to an external site. for a longer video on how to interpret the statistical software output.
As you work on this assignment, refer to the 7864 Data Set Instructions [PDF] document for information on variables used in this course.
Download the 7864 data set, grades.jasp, which is 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, and Week 8).
Part 1
Create two histograms for visual interpretation using the following variables:
| 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 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 with regard to normality.
Submit both sections of your assignment as an attached Word document.I
cant attach the JASP data here it wont allow me to attach I would have to email that attachment but if yu click the grades.jasp document in blue it should let you download it
