The mean is the usual , so: add them and divide the sum by number of data
35
45
30
35
40
25

The mean is .

The mode is the number that is

than any other, so is the mode.
The median is the , so I'll have to rewrite the list in order:
25
30
35
35
40
45
There are six numbers in the list, so the middle one will be the (3rd or 4th)number:
So, the median is .

The variance is a measure of how far each value in the data set is from the mean. Here is how it is defined:
Subtract the mean from each value in the data. This gives you a measure of the distance of each value from the mean.
The mean is .

is simply the (positive) square root of the variance.
