Understanding Descriptive Statistics

What is the mean of the following data set: 4, 8, 6, 5, 3?

• 6.0

• 5.2

• 4.5

• 7.2

In a data set, if the median is 10 and the mode is 8, what can you infer about the distribution?

• The distribution is likely left-skewed.

• The distribution is likely normal.

• The distribution is likely right-skewed.

• The distribution has no mode.

How do you interpret a standard deviation of 0 in a data set?

• A standard deviation of 0 suggests the data points are randomly distributed.

• A standard deviation of 0 means the data set is empty.

• A standard deviation of 0 indicates a large spread of data points.

• A standard deviation of 0 means all data points are the same.

If the range of a data set is 15 and the minimum value is 5, what is the maximum value?

• 10

• 30

• 20

• 25

What does a high variance indicate about a data set?

• High variance indicates a wide spread of data points.

• High variance means the data points are clustered closely together.

• High variance indicates that all data points are identical.

• High variance suggests that the data set has no outliers.
