If the range of a data set is 18, estimate the standard deviation of the data.

Expert Solution

Compute the standard deviation by using the range rule of thumb.

The estimated standard deviation is,

s ≈ Range(R)/4 …… (1)

Substitute 18 for R in Equation (1).

Therefore,

s ≈ 18/4

≈ 4.5

Thus, the value of standard deviation is approximately 4.5.
