How it is calculated
Population standard deviation is sqrt(sum((x − mean)²) / N). The entered observations define the full population; the denominator is N, not sample denominator N − 1.
Assumptions
Fuel economy, traffic, prices, maintenance, and vehicle conditions can differ from the entered values.
Example
For 2, 4, 4, 4, 5, 5, 7, 9 the mean is 5 and population standard deviation is 2, displayed as 2.0000.
Limitations
Confirm current prices, vehicle specifications, tolls, and route conditions before committing money or time.
