• mean

• median

• quartile

Multiple Choice

The mean is the average; It is the amount that each person/group would get if everything was divided fairly and equally by all. Which of the following describes steps for finding the mean?

• Add the values. Then divide by the number of values.

• Order the values from least to greatest. Then identify the middle value.

• Identify the value that appears most frequently.

Multiple Choice

The median is the middle value in a set of data. Half of the values will be below the median. Half of the values will be above the median. Which of the following describes steps for finding the mean?

• Add the values. Then divide by the number of values.

• Order the values from least to greatest. Then identify the middle value.

• Identify the value that appears most frequently.

Multiple Select

The median is the middle value in a set of data. If there are 100 values in a data set, which of the following is true? Choose all that apply.

• There are 50 values below the median.

• There are 50 values above the median.

• The mean is 50
