Question 1

Find the mean, median and mode of the following 10 test scores.

9, 6, 14, 8, 8, 4, 18, 17, 12, 8

Mean: Expected answer:

Median: Expected answer:

Mode: Expected answer:

Give your answers to 1 decimal place where appropriate.

The median is the middle score, when the scores are arranged in order. In this case the number of scores is even, so we need to find the mean of the 5th and 6th scores.

Advice

The mean, median and mode are all averages. Each gives us some information about a typical member of a set of data.

To calculate the mean, you need to find the total of all the test scores and divide it by the number of scores -- in this case 10.

The median is the middle score, when the scores are arranged in order. In this case the number of scores is even, so we need to find the mean of the 5th and 6th scores.

The mode is the most frequent score.
