Question

Here are a list of numbers.

51,38,48,36,39,40,39,47
a) Work out the range of the numbers in the list.
b) Work out the mediann of the numbers in the list

Answer 1

Explanation:

easy by applying formula of range and median

Answer 2

• range: 15
• median: 39.5

Explanation:

The range of the data is the difference between the largest and smallest values. The median is the middle value, or the average of the two middle values.

a) Range

Arranging the data from lowest to highest, we have ...

36, 38, 39, 39, 40, 47, 48, 51

The difference between the highest and lowest values is ...

range = 51 -36 = 15

The range of the data is 15.

b) Median

The median of the data set is the middle value, or the average of the two middle values if the number of data values is even.

There are 8 members of the data set, so the median will be the average of the two middle values: 39 and 40.

median = (39 +40)/2 = 39.5

The median of the numbers on the list is 39.5.
