I need help with a Statistics question. All explanations and answers will be used to help me learn.

Considering the following data

[0,1,2,3,4,5,6,20,21,22,23,24,25]

The distribution is considered to be: *

• Skewed to the right
• Skewed to the left
• Not skewed

Which of the following describe the middle part of a group of numbers? *

1- measure of variabilty

2-measure of central tendency

3- measure of association

4- measure of shape

The sum of the deviations about the mean is always?

1- range

2-standard deviation

3- negative

4- zero

I’m trying to study for my Writing course and I need some help to understand this question.

In this activity, you will evaluate two students’ practice tests.

This activity serves two purposes.

1) You will see examples of multiple-choice questions of varying quality.

2) You will begin practicing monitoring the accuracy of creating multiple-choice questions.

What to Do:

• Record the number of points you think each student earned
• Suggest two ways the tests could be improved
• Scan worksheets into one file (e.g., use Adobe Scan on smart phone)
• Upload a single file of the worksheets on eCampus
