anonymous · Answer

then you divide by 10, so move the decimal point over.

anonymous · Answer

49.31?

anonymous · Answer

Yes.
There ya go. The mean is always the sum of the numbers divided by the amount of numbers, if I am not mistaken.

Wait, I;m sorry, I have calculated it wrong, I was finding standard mean. My bad.

anonymous · Answer

i don't really understand it @jim_thompson5910

jim_thompson5910 · Answer

which part doesn't make sense?

anonymous · Answer

the subtraction???

jim_thompson5910 · Answer

you subtract each value from the mean and take the absolute value of that difference (to make sure it's positive)

jim_thompson5910 · Answer

It looks like you already found the mean to be 49.31

so $$\Large \mu = 49.31$$

or $$\Large \overline{x} = 49.31$$
