Question

What conclusion can be derived by comparing the central tendencies of the two data sets?

A:{7, 6.3, 1.6,2,4,6,3,5}
B: {2, 2, 2, 3, 4, 5, 2, 8, 7, 6}

Answer 1

See below.

Explanation:

The mean of set A = 4.3625

The mean of set B = 4.1.

The means are very close.

The median of set A = 4.5

The median of set B = 3.5.

The mean and median of Set A are quite close so we can say that the data is close to Symmetrical.

In the case of set B the mean and median are further apart so the data is more skewed . it is skewed towards the lower values (to the left).
