For this exercise, we were asked to find the mean, the median, and the mode for this data.
00:06
So starting with the mean, for any dataset, this is equal to the sum of all of the data points, divided by the size of the dataset.
00:31
We have 10 plus 7 plus 6, plus 10 plus 6, plus 10 plus 6, plus 15, divided by 6, because there are 6 data points.
00:47
And this comes out to a mean of 9.
00:49
Then for the median, the way to find the median is to sort the data numerically.
01:01
So let's first do that.
01:02
So we have 6, 6, 7, 10, and 15.
01:15
And then we want to find the middle -most data point when they're sorted numerically.
01:21
Now since we have an even number of data, there's two data points that are in the middle.
01:26
That's 7 and 10.
01:28
So we take the average of these two data points and treat that as the median.
01:41
And so this gives us eight and a half.
01:47
And then we want the mode.
01:49
The mode is the data point that occurs most frequently...
