Question

Listed below are the arrival delay times (in minutes) of randomly selected airplane flights from one airport to another. Negative values correspond to flights that arrived early before the scheduled arrival time, and positive values represent lengths of delays. Find the range, variance, and standard deviation for the set of the sample values are negative, but can the standard deviation ever be negative? -27 -7 -1 -1 3 -24 -9 The range of the sample data is minutes. (Round to one decimal place as needed.)

Explanation / Answer

No the standard deviation can never be negative.

Range is the difference between the smallest and the largest value in the data.

So the range for this data is: 3-(-27) = 30 minutes
