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}

See below.

Step-by-step 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).

step-by-step explanation:

y = | -2(-2) |     →     y = | 4 |     →     y = 4       ⇒   (-2, 4)

y = | -2(-1) |     →     y = | 2 |     →       y =   2       ⇒   (-1, 2)    

y = | -2(0) |     →     y = | 0 |     →       y = 0         ⇒   (0, 0)

y = | -2(1) |   c →     y = | -2 |     →     y =   2         ⇒   (1, 2)    

y = | -2(2) |     →     y = | - 4 |     →     y =   4         ⇒   (2, 4)
