Mean, Median, Mode, Range

Front

What is the mean?

Back

The mean is the average of a set of numbers, calculated by adding all the numbers together and dividing by the total count of numbers.

Front

What is the median?

Back

The median is the middle number in a sorted list of numbers. If there is an even number of values, the median is the average of the two middle numbers.

Front

What is the mode?

Back

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

Front

What is the range?

Back

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

Front

How do you calculate the mean of 5, 11, 2, 12, 4, 2?

Back

Add the numbers: 5 + 11 + 2 + 12 + 4 + 2 = 36. Then divide by the count (6): 36 / 6 = 6.

Front

What is the median of the set 4, 3, 15, 11, 3, 8, 7, 5?

Back

First, sort the numbers: 3, 3, 4, 5, 7, 8, 11, 15. There are 8 numbers, so the median is the average of the 4th and 5th numbers: (5 + 7) / 2 = 6.

Front

What is the mode of the set 1, 0, 1, 5, 6, 3, 4?

Back

The mode is 1, as it appears most frequently.

Front

What is the range of the scores 155, 165, 138, 172, 127, 193, 142?

Back

The range is calculated as 193 (highest) - 127 (lowest) = 66.

Front

Which number is not the mean, median, mode, or range of the data set 4, 3, 15, 11, 3, 8, 7, 5?

Back

The number 11 is not the mean, median, mode, or range.

Front

How do you find the mode in a data set?

Back

Identify the number that appears most frequently. If no number repeats, there is no mode.
