Which of the following numbers would be an outlier if added to the data set below?

372, 351, 299, 406, 387, 315, 364, 308

406,209,308

According to their deviation from the mean 350.25

Step-by-step explanation:

To Know an outlier we'll determine it by looking for the mean of the data set first then checking the deviation of the numbers each from the mean.

Mean = (372+351+299+406+387+315

+364+308) / 8

Mean = 2802/8

Mean = 350.25

Ok now let's determine the deviations

372 - 350.25 = 21.75

351 - 350.25 = 0.75

299 - 350.25 = - 51.25

406 - 350.25 = 55.75

387 - 350.25 = 36.75

315 - 350.25 = - 35.25

364 - 350.25 = 13.75

308 - 350.25 = - 42.25

According to the magnitude of the deviation 406 and 299 has the highest deviation so they are the outliers followed by 308
