Question
I’m very confused on how I’m supposed to calculate the two blank columns. The formula has me a bit confused. What exactly am I supposed to subtract? Is “Xi”the number of cells per ml? If so what is “X” represent.

**See below for calculation of the variance and standard
deviation
The mean
X = E Xi
(E Xi = sum of the individual values; n = number of samples)
n
*n-1 is the statistical convention when dealing
The variance (s²) = E (Xi-X)²
(n-1)*
with samples from a single population.
