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

Step-by-step explanation

we have the weights of 7 rabbits as:

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

To compute the mean, mode, median and range for this data, we will first have to re-arrange the data from smallest to largest

So we will have

`1.1,\text{ 1.3, 1.3, 1.5, 1.7, 1.9, 2.0}`

The mean is simply the average of the set which is

`\begin{gathered} mean=\frac{sum\text{ of all numbers}}{total\text{ numbers}}=(1.1+1.3+1.3+1.5+1.7+1.9+2.0)/(7)=(10.8)/(7) \\ \\ mean=1.54kg \end{gathered}`

Mean =1.54kg

The mode is simply the data that occurs most

In our case, this is 1.3kg because it occurs twice

Mode = 1.3kg

Median

This is the middle number of the data set,

In our case, the median is 1.5kg

The range is the difference between the highest and smallest number

In our case, the range is

`2.0-1.1=0.9kg`

Range =0.9kg
