So, here we have been provided a data and asked to compute the value of the mean, median and mode.
00:06
Now, for this data, the total number of observations here are 20.
00:13
So, our mean is sum of all the observations divided by the total number of observations.
00:18
So, this is equal to 0 .276 plus 0 .317 plus up to the last value that is 0 .293 divided by 20.
00:28
And this is equal to, this is 0 .3017.
00:39
Now we have to compute the value of the median.
00:46
So, for that we first need to arrange our data in the ascending order.
00:51
So, this is 0 .276, 0 .276, 0 .280, 0 .281, 0 .285, 0 .292, 0 .292, 0 .293, 0 .293, 0 .299, 0 .302, 0 .308, 0 .308 plus 0 .309 plus, sorry this is not plus, 0 .309, 0 .311, 0 .317, 0 .319, 0 .323, 0 .325, 0 .326 and 0 .327, right.
01:41
So, median is the average of the middle two terms for an even set of data...
