Hey there, welcome to numerate.
00:05
So we have a couple of questions here, six and seven, asking for the characteristic or measure, statistical measure.
00:15
So we have number six.
00:18
A measure of spread called the blank is constructed by subtracting the lowest variance from the highest score.
00:25
Oh, sorry, lowest score from the highest score.
00:28
So from here, there's several measures that measures spread.
00:35
The main ones are variance, standard deviation, and range.
00:55
So standard deviation, variance, first.
00:59
The equation would be basically the sum of squares, x minus the x mean squared, divided by n minus 1.
01:13
For example, the standard deviation is the same thing, but it's going to be square root of that...
