Mode, Median, Mean, Range, and Outliers

Front

What is the median of a data set?

Back

The median is the middle value when the data is ordered from least to greatest. If there is an even number of values, it is the average of the two middle values.

Front

How do you calculate the mean?

Back

The mean is calculated by adding all the values together and then dividing by the number of values.

Front

What is the mode of a data set?

Back

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

Front

What is the range of a data set?

Back

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

Front

How do you find the median if there is an even number of values?

Back

Order the values in ascending order, then add the two middle values and divide by 2.

Front

What does it mean if the mean is greater than the median?

Back

If the mean is greater than the median, it suggests that there are higher values (outliers) that are pulling the mean up.

Front

What is an outlier?

Back

An outlier is a value that is significantly higher or lower than the other values in a data set.

Front

If a data set is: 3, 5, 7, 9, 11, 8, 3, what is the median?

Back

The median is 7.

If a data set is: 3, 5, 7, 9, 11, 8, 3, what is the mode?

Back

The mode is 3.

If a data set is: 3, 5, 7, 9, 11, 8, 3, what is the range?

Back

The range is 8 (11 - 3 = 8).
