Answer:
In order to find the variance and deviation we need to find the mean with this formula:
And replacing we got:
Now we can find the variance with the following formula:
And replacing we got:
And the standard deviation would be:
For this case since the range observed is large is better to use a measure of variation in order to check the spread of the values and take a decision useful
Step-by-step explanation:
For this case we have the following dataset:
60 58 55 53 47 45 44 43 25 25 20 18 7 5
We can find the range with this formula:
And replacing we got:
