Question

Christopher has seven rabbits in his garden. Their weights, in kg, are listed below. 1.1, 1.9,1.5,1.3, 2.0,1.3,1.7 Calculate the mean, mode, median and range for this data.

Answer 1

Mean = 1.54

Mode = 1.3

Median = 1.5

Range = 0.9

EXPLANATION :

From the problem, we have the following weights.

1.1, 1.9, 1.5, 1.3, 2.0, 1.3, 1.7

Arrange the data from least to greatest.

1.1, 1.3, 1.3, 1.5, 1.7, 1.9, 2.0

The mean is the average of the data

That will be :

`(1.1+1.3+1.3+1.5+1.7+1.9+2.0)/(7)=1.54`

The mode is the data with the most number of appearance.

In this case, 1.3 appears twice.

So the mode is 1.3

The median is the middle data, since there are 7 data, the middle term is the 4th term

That will be 1.5

The range is the difference between the greatest and least data.

That will be 2.0 - 1.1 = 0.9
