Front

What is the median in a data set?

Back

The median is the middle value when the data set is ordered from least to greatest.

Front

How do you calculate the range of a data set?

Back

The range is calculated by subtracting the smallest value from the largest value in the data set.

Front

What is the mode of the data set: 2, 3, 4, 4, 5?

Back

The mode is 4, as it appears most frequently.

Front

If the data set is 10, 20, 30, 40, what is the mean?

Back

The mean is (10 + 20 + 30 + 40) / 4 = 25.

Front

What is the median of the data set: 1, 3, 3, 6, 7, 8?

Back

The median is (3 + 6) / 2 = 4.5.

Front

What is the range of the data set: 5, 10, 15, 20?

Back

The range is 20 - 5 = 15.

Front

What does it mean if a data set has no mode?

Back

It means that no number appears more than once in the data set.
