Let's solve the given questions according to the question in first part we are having a data 16, 8, 11, 11, 14, 22, 20, 16, 30, 25, 19.
00:20
So the mean is sum divided by number of observation.
00:32
To 1 divided by 13 so it is equals to 17 now in the second part median so data in ascending order 8 9 11 14 15 16 16 19 20 22 25 30 so therefore middle value that is median is equals to 16.
01:17
Now moving to part 3, then mode is most repeated value.
01:31
So therefore, mode is equals to 16.
01:36
Now in the fourth q, first quartile is median of left of median of data.
01:59
So the left of median data is 8, 9, 11, 14, 15, 16...
