In this problem, we are given the data set which includes the values 4, 10, followed by 7 appearing twice, followed by 6, 9, 3 and 8.
00:12
So first we are required to get the mean, median, as well as the mode of this data set.
00:20
So to get the mean, we will simply use this formula, according to which we see that the mean is obtained when we add the data values right from the first to the last and we divide this with the size of the sample which is 8 here and we see that this simplifies to 6 .75.
00:38
And next to compute the median, we will first arrange this data set in the increasing order.
00:43
So when we do that, we get 3 followed by 4, then we have 6 followed by 7 appearing twice, then we have 8, 9 and 10.
00:51
And we see that there are two values here which are lying at the center and they are these two 7s.
00:58
So the median here, this would be the mean of these two 7s...
