Answer:

sd= [tex]\sqrt{\frac{S(ni-M)^{2} }{N} }[/tex]    with S the sum from i=1 to N

Step-by-step explanation:

the standard deviation is the average separation between the data provided

in this case the standard deviation of the words per page is

sd= [tex]\sqrt{\frac{S(ni-M)^{2} }{N} }[/tex]

with i= each page number,  N= total number of pages,  

M= average= ∑ni / N ,  ∑since 1 to N
