The range in a data set is the highest value minus the lowest value.
The standard deviation is a quantity expressing by how much the members of a group differ from the mean value for the group.
City A (data set)
[tex]1.00,1.00,1.25,1.50,1.50[/tex]
City B (data set)
[tex]0.00,1.00,1.75,1.75,2.25[/tex]
City A Range
The range is 1.50 - 1.00 = 0.50
City B Range
The range is 2.25 - 0.00 = 2.25
Now,
The formula for sample standard deviation is
[tex]s=\sqrt[]{\frac{\sum(x-\bar{x})^2}{n-1}}[/tex]
Where
s is the sample standard deviation
x bar - mean of the sample
n is the number of numbers in the data set
Using a standard deviation calculator, let's calculate the standard deviation of both data sets.
City A Standard Deviation
The standard deviation is
[tex]s=\sqrt[]{\frac{(1.00-1.25)^2+\cdots(1.50-1.25)^2}{5-1}}=0.25[/tex]
City B Standard Deviation
The standard deviation is
[tex]s=\sqrt[]{\frac{(0.00-1.35)^2+\cdots(2.25-1.35)^2}{5-1}}=0.8768[/tex]
From the data calculations, we can see that City B
