Over the first five years of owning her car, Gina drove about 12,200 miles the first year, 16,211 miles the second year, 12,050 the third year, 11,350 the fourth year, and 13,325 the fifth year. Find the mean, median, and mode of this data.

mean = 12,200; median = 12,200; no mode

mean = 13,027; median = 12,200; mode = 4,861

mean = 12,200; median = 13,027; no mode

mean = 13,027; median = 12,200; no mode

    The answer is mean = 13,027; median = 12,200; no mode

    Let's rearrange values from the lowest to the highest:

    11350, 12050, 12200, 13325, 16211

    The mean is the sum of all values divided by the number of values:

    (11350 + 12050 + 12200 + 13325 + 16211) / 5 ≈ 13027

    The median is the middle value. If there is an odd number of data, then the median is the value in the middle. In the data set 11350, 12050, 12200, 13325, 16211, the median (the middle value) is 12200

    The mode is the value that occurs most frequently. Since none of the number does not occur most frequently, there is no mode.

    (12,200 + 16,211 + 12,050 + 11,350 + 13,325) / 5 = 65136/5 =

    13027.2 < = = this is the mean (average)

    11,350, 12,050, 12,200, 13,325, 16,211

    median (middle number) = 12,200

    there is no mode ... a mode is a number that appears most often ... all the numbers appear once in this data.
