Answer: 8.3
Step-by-step explanation:
To find the variance, you want to find the mean of the data.

Now that we have the mean, we find the difference between each data point and the mean.
3-5=-2
3-5=-2
8-5=3
1-5=-4
9-5=4
6-5=1
With the difference, you square each and find the average.
(-2)²=4
(-2)²=4
3²=9
(-4)²=16
4²=16
1²=1

The variance is 8.3.
