Data given is 45, 100, 61, 65, 60, 50, 99, 70, 80, 25, 53, 83, 70, 57, 78, 70, 72 and 69.
00:34
So, first we need to calculate the mean.
00:38
So, mean is equal to sum of all scores divided by number of scores which is equal to putting the values 45 added to 100, added to 61, added to 65, added to 50, added to 99, added to 70, added to 80, added to 25, added to 53, added to 83, added to 70, added to 57, added to 78, added to 70, added to 72, added to 69 is divided by 17.
01:24
So, evaluating it we get approximately 67 .41 which is rounded to two decimal places.
01:34
Next we have to calculate the median.
01:36
So, to find median we have to first arrange these scores in ascending order.
01:41
So, 25, 45, 50, 53, 57, 61, 65, 69, 70, 70, 70, 72, 78, 80, 83, 99 and 100...
