Answer #1

A) Mean of the data is the ratio of sum of data value to the number of data values

That is

B) Arrange the data values in ascending order we get

As there are 8 data values the median is the mean of 4th and fifth data values that is 62 and 64 which is 63

So

C) Mode is the value which appears most frequently

Here 52 appears 3 times.

So

D) range is the difference between the greatest and lowest

That is

E) The standard deviation is given by

F) The first quartile is and the third quartile is
