Hey there, welcome to numerate.
00:02
So we're asked to find the range, sample standard deviation, and variance for these 11 jersey numbers here.
00:11
And what do the results tell us? so basically over here, we have the jersey numbers.
00:20
So we're going to find the range first.
00:23
So our range equals basically max minus the min, our largest value minus our smallest value.
00:38
So basically, we have the range equal.
00:42
So let's find our maximum value here.
00:45
Our maximum value, if we look, we have 71, we have 80.
00:50
Let's see if there's anything higher than that.
00:53
And it just looks like our maximum value is 80.
00:56
So we take 80 minus our smallest value.
01:00
And it looks like our smallest value here is just nine.
01:07
Yep, it is nine.
01:09
So we're just going to do 80 minus 9, which equals 71.
01:13
So our range over here is 71...
