Front

What is the mode of a data set?

Back

The mode is the value that appears most frequently in a data set.

Front

How do you find the median of a data set?

Back

To find the median, arrange the numbers in ascending order and identify the middle value. If there is an even number of values, the median is the average of the two middle values.

Front

What is the range of a data set?

Back

The range is the difference between the highest and lowest values in a data set.

Front

What is the formula for calculating the mean?

Back

The mean is calculated by adding all the numbers in a data set and dividing by the number of items in the set.

Front

If a data set has no repeating numbers, what is the mode?

Back

If there are no repeating numbers, the data set has no mode.

Front

In the data set {12, 10, 10, 10, 13, 12, 11, 13, 10}, what is the mode?

Back

The mode is 10, as it appears most frequently.

Front

In the data set {6, 5, 5, 9, 8, 7, 9}, what are the modes?

Back

The modes are 5 and 9, as both appear most frequently.

Front

What is the median of the data set {4, 2, 5, 7, 1}?

Back

The median is 4, as it is the middle value when the numbers are arranged in order.

Front

What is the median of the data set {35, 42, 40, 25, 42, 54, 50}?

Back

The median is 42, as it is the middle value when the numbers are arranged in order.

Front

What does it mean if a data set has multiple modes?

Back

If a data set has multiple modes, it is called multimodal, indicating that there are multiple values that appear with the highest frequency.
