What is the median of a data set?

Back

The median is the middle value of a data set when the numbers are arranged in order. If there is an even number of observations, the median is the average of the two middle numbers.

How do you find the median of the numbers: 4, 2, 7, 4, 3?

Back

Arrange the numbers in order: 2, 3, 4, 4, 7. The median is 4.

What is the median of the data set: 3, 17, 17, 11, 8, 13, 5, 18?

Back

Arrange the numbers in order: 3, 5, 8, 11, 13, 17, 17, 18. The median is the average of 11 and 13, which is 12.

What is the mean of a data set?

Back

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

Front

How do you find the mean of the numbers: 28, 18, 19, 18, 17?

Back

Add the numbers: 28 + 18 + 19 + 18 + 17 = 100. Divide by the count (5): 100 / 5 = 20.

Front

What is the mode of a data set?

Back

The mode is the number 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 a data set.

Front

How do you calculate the range of the numbers: 4, 2, 7, 4, 3?

Back

The highest number is 7 and the lowest is 2. The range is 7 - 2 = 5.

What is the importance of finding the median in a data set?
