Question

Find the mean, median, and mode of the data set 67, 52, 50, 99, 66, 50, and 57 with and without the outlier. which measure does the outlier affect the most?

Answer 1

Mean - 63

Median - 57

The Mean affects the outlier the most.

Explanation:

Mean is where u add all the numbers up and then divide them by how many are there. So 50 + 50 + 52 + 57 + 66 + 67 + 99 = 441. There are 7 numbers so 441/7 which equals 63. So mean is 63.

For median u order them least to greatest which is 50,50,52,57,66,67,99. The median is the middle number of this set which is 57.

Outlier is the first number which is 50. So the mean is the answer for which measure does the outlier affect the most bc 63 is bigger than 57 the median. So basically which is a more difference.
