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 the numbers 1, 0, 1, 5, 6, 3, 4?

Back

Add the numbers: 1 + 0 + 1 + 5 + 6 + 3 + 4 = 20. Then divide by the count of numbers (7): 20 / 7 = 2.85.

Front

What is the median of the data 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

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

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

Back

The mode is 3, as it appears most frequently.

Front

How do you find the range of Roger's bowling scores: 155, 165, 138, 172, 127, 193, 142?

Back

Identify the highest score (193) and the lowest score (127). The range is 193 - 127 = 66.

Front

What is the formula for calculating the mean?

Back

Mean = (Sum of all values) / (Number of values).
