Over the first five years of owning 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.
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.
A) Mean = 13155.6 , Median = 12700 and no mode.
Mean:(add all the values up and divide them by how many there are) 12700+15478+12675+11850+13075=65778.Divide it by 5,it should equal to 13155.6
Median:(middle value) That is, 12675
Mode:(Recurring value) N/A (There is none)
The best measure of central tendency I would choose,in my opinion, is the mean.The mean is calculated using all the values available and hence it’s more accurate for prediction.Source(s): Maths teacher
divided by 5
middle number (median)=
there is no mode
The mean is the best way to estimate/predict how many miles Gina will drive in the sixth year………if you need the overall of six years….
=avg x 6
you shouldn’t need a calculator 🙂
