The lengths of the electical extension cords in a workshop are 6 ft, 8 ft, 25 ft, 8 ft, 12 ft, 50 ft, and 25 ft. what are the mean, median, mode, and range of the lengths of the cords in inches?

Mean. 

We determine first the sum of the given lengths. Then, divide the sum by the total number of items. That is,
                          mean = (6 ft + 8 ft + 25 ft + 8 ft + 12 ft + 50 ft + 25 ft) / 7 
                                   mean = 19.14 ft

Median.

We arrange the items from least to lowest. Then, determine the middle term.
                                    6 ft, 8 ft, 8 ft, 12 ft, 25 ft, 25 ft, 50 ft
The middle term (which is the median term) is 12 ft.

Mode.

We count how many times a certain item appears in the set and the highest count, will be the mode. From the given set of numbers, the mode is 8 ft and 25 ft. 

Range.

We subtract the shortest length from the longest length. The answer will then be 50 ft - 8 ft equal to 42 ft.
