celebrities with the 10 highest incomes in a recent year. The celebrities in order are Steven
Spielberg, Howard Stern, George Lucas, Oprah Winfrey, Jerry Seinfeld, Tiger Woods, Dan

Remember the formula for calculating the range and standard deviation. 

The range is Maximum minus the minimum value. When the above values are sorted in ascending order:

67  75  84  88  90 100 225 235 302 332, 

Range  = 332 - 67  = 265. 

Variance formula: 

Apply the formula above and the variance will be;- 10547.96, The standard deviation is the square root of variance.
