Question

Over the first five years ownibg her car, Gina drove about 12,700 miles the first year, 15,478 miles the second year, 12,675 the third year, 11,850 the fourth year, and 13,075 the fifth year. Find the mean, median, and mode of this data

Answer 1

Begin by recording your data down first, and it helps to write them down in order too.
So [11,850 - 12,675 - 12,700 - 13,075 - 15,478]

Answer 2

To find the mean of a set, you have to add all of the quantities within the set and then divide the total by the number of quantities in the set itself.
In this case, that would look like:
11,850 + 12,675 + 12,700 + 13,075 + 15,478 = 65,778

Then

65,778/6 = your mean

Answer 3

To find the median of a set with 6 quantities [or any even number of quantities], you must take the average of the 2 numbers in the middle, in this case: 12,700 and 13,075
