Exercise 13 Page 430

It may be easier to calculate the median, and mode if you rearrange the numbers first.

Median: 7
Mode: 3

Practice makes perfect
We want to find the median, and mode of the given data set. 3, 5, 7, 9, 11, 3, 8 The median is the value that divides the ordered set into two halves. The first thing we have to do to find the median is to rearrange the set so that it is in order from least to greatest.

3, 3, 5, 7, 8, 9, 11 The number of values in our set is 7. This is why the median is the fourth value in order, 7. Now we want to find the mode. The mode is the most common value in the set. Let's take a look at the ordered set one more time! 3, 3, 5, 7, 8, 9, 11 We can see that the most common value in the given data set is 3. This is the mode of our data set. Median: 7 Mode: 3
