First, you need to find the mean of all this set of numbers. You would add them all together and then divide by 6 which is 50.5.
Now you find the sample variance. Subtract each number from the mean.
<span>15.5, 13.5, 8.5, -6.5, -10.5, -19.5 </span>
After, you square each value and add them.
<span>240.25+182.25+72.25+42.25+110.25+380.2... </span>
<span>= 1027.5 </span>
Now divide by 5 (because it's a sample variance) and you get 205.5.
Divide it up by 5 because 9+6=15
Or u could divide it up by 3
