Use SPSS to answer the following questions. (Hint: For instructions use the SPSS Instruction Manual posted to the module as a reference for all SPSS output). Paste all SPSS output into the document below. Answer all questions fully.

1. Create a new variable called WeeklySPtime. This should be TotalTimeSpent/16.

2. Create a histogram for WeeklySPtime.

3. Describe the shape of the distribution.

4. Calculate the mean, standard deviation, median, min, and max for WeeklySPtime.

5. Write a sentence or describing on how much time students spend on their study plan.

6. Create a scatter plot of weeklySPtime and FinalGradePercentage.

7. Does it look like there is a trend between the two? Yes/No. Explain your answer.

8. Important question: Are the values calculated here statistics or parameters? Do they relate to the sample or to the population?

9. Create a side-by-side boxplot of the weeklySPtime for face-to-face and online students. Compare the plots, do you see large differences between the two types of classes?

Answer 1

Answer:

1. Create a new variable called WeeklySPtime. This should be TotalTimeSpent/16.

2. Create a histogram for WeeklySPtime.

3. Describe the shape of the distribution.

The plot shows that data are positively skewed.

4. Calculate the mean, standard deviation, median, min, and max for WeeklySPtime.

Statistics
WeeklySPtime
N	Valid	60
	Missing	0
Mean		89.6135
Median		62.8750
Std. Deviation		99.06380
Minimum		5.88
Maximum		493.06

5. Write a sentence or describing on how much time students spend on their study plan.

The students spend on their study plan for about 89.6 hours per week. Minimum value is 5.88 and maximum is 493.06.

6. Create a scatter plot of weeklySPtime and FinalGradePercentage.

7. Does it look like there is a trend between the two? Yes/No. Explain your answer.

The scatter plot shows that there is no trend. There is no pattern or no obvious relation between the two variables .

8. Important question: Are the values calculated here statistics or parameters? Do they relate to the sample or to the population?

The values calculated here are based on sample, therefore statistics. They are describing the sample data.

9. Create a side-by-side boxplot of the weeklySPtime for face-to-face and online students. Compare the plots, do you see large differences between the two types of classes?

The plot shows that there is not much difference between the two types of classes.
