Question

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. a. Find the mean, median, and mode of this data. b. Explain which measure of central tendency will best predict how many miles Gina will drive in the sixth year.
mean = 13,027; median = 12,200; no mode; the mean is the best choice because it is representative of the entire data set.

mean = 13,027; median = 12,200; no mode; the median is the best choice because it is not skewed by the high outlier.

mean = 13,027; median = 12,200; mode = 4,861; the median is the best choice because it is not skewed by the high outlier.

mean = 12,200; median = 13,027; no mode; the mean is the best choice because it is representative of the entire data set.

I think its D. but im not sure please help?!?!

Answer 1

(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.

Answer 2

I think it is a or b for answer
