Show the Sturgis Rule Calculation and then fill in the chart for the Cell Boundaries N = 100 High Value = 111,200 Low Value = 74,800 (no values...

Sturges' rule is a way of calculating the number of bins (e.g. categories or classes) of a set of data. It is assumed that the data come from a normally distributed population.

Sturges' rule states that the number of bins should be the ceiling function of (1+log(2)n) (log base 2 of n, where the ceiling function returns the next higher integer.)

Here we have 1+log(2)100 is approximately 1+6.64385619=7.64385619 so the number of bins should be...

Sturges' rule states that the number of bins should be the ceiling function of (1+log(2)n) (log base 2 of n, where the ceiling function returns the next higher integer.)

Here we have 1+log(2)100 is approximately 1+6.64385619=7.64385619 so the number of bins should be 8.

We can find the class width by (111200-74800)/8=4550, so we use 4551 as the class width.
