The five-number summary is a descriptive statistic that provides information about a set of observations. It consists of the following statistics:

1. Minimum (Min) – the smallest observation

2. Maximum (Max) – the largest observation

3. Median M – the middle term

4. First Quartile Q1 – the middle term of values below the median

5. Third Quartile Q3 – the middle term of values above the median

Arrange the terms in ascending order.

13,14,15,27,27,28,28,29,30,31,32,32,35,36,38,38

The minimum value is the smallest value in the arranged data set.

13

The maximum value is the largest value in the arranged data set.

38

The median is the middle term in the arranged data set. In the case of an even number of terms, the median is the average of the two middle terms.

29+302

Remove parentheses.

29+302

Add 29 and 30.

592

Convert the median 592 to decimal.

29.5

29.5

The lower half of data is the set below the median.

13,14,15,27,27,28,28,29

The median for the lower half of data 13,14,15,27,27,28,28,29 is the lower or first quartile. In this case, the first quartile is 27.

The median is the middle term in the arranged data set. In the case of an even number of terms, the median is the average of the two middle terms.

27+272

Remove parentheses.

27+272

Add 27 and 27.

542

Divide 54 by 2.

27

Convert the median 27 to decimal.

The upper half of data is the set above the median.

30,31,32,32,35,36,38,38

The median for the upper half of data 30,31,32,32,35,36,38,38 is the upper or third quartile. In this case, the third quartile is 33.5.

The median is the middle term in the arranged data set. In the case of an even number of terms, the median is the average of the two middle terms.

32+352

Remove parentheses.

32+352

Add 32 and 35.

672

Convert the median 672 to decimal.
