the average right

I think I got the mean
m-5= 0.74
so m should be 5.74!??
but I don’t know how to find the standard deviation of m
raw rune
but I don’t know how to find the standard deviation of m
so standard deviation is a measure of how spread out the data is
shifting all the data by a set amount doesnt change how spread out it is
so standard deviation is actually the same
