1
00:00:00,060 --> 00:00:01,530
This is an exercise for you.

2
00:00:01,920 --> 00:00:12,090
Your task is to calculate the mean value of this column, so the average of all these values and plays

3
00:00:12,090 --> 00:00:14,700
that average value in this cell here.

4
00:00:15,000 --> 00:00:16,560
So 26.

5
00:00:18,650 --> 00:00:26,440
Just the tip to calculate the mean, you can improve the statistics module and then use statistics,

6
00:00:26,450 --> 00:00:29,930
that's mean which expects a list as inputs.

7
00:00:30,320 --> 00:00:32,689
So beware of this is a plain list.

8
00:00:35,710 --> 00:00:43,030
When you get the values of this column with spreads, you're going to get the list of lists so the values

9
00:00:43,030 --> 00:00:45,910
will be embedded inside those lists.

10
00:00:45,940 --> 00:00:46,930
So be aware of that.

11
00:00:47,170 --> 00:00:50,200
And good luck, I'll give you the solution in the next video.
