Question

fill in the blank. the range rule of thumb roughly estimates the standard deviation of a data set as the range rule of thumb roughly estimates the standard deviation of a data set as s = (mean)+2(standard deviation) s = (mean)-2(standard deviation) s = \frac{range}{2} s = \frac{range}{4}

Explanation:

The Range Rule of Thumb states that the standard - deviation of a data set can be roughly estimated by dividing the range of the data set by 4. This is a quick and easy way to get an approximate value of the standard deviation without doing the full calculation.

Answer:

s = $\frac{range}{4}$
