Question

The number of toys owned by eight classmates is shown below:

Answer 1

Answer:

3

Step-by-step explanation:

The first step is to find the mean of the data set

mean = $\frac{4+3+4+5+6+6+8+4}{8}$ = $\frac{40}{8}$ = 5

Next take the absolute value of the difference between each data member and the mean, that is

| 4 - 8 | = | - 4 | = 4

| 3 - 8 | = | - 5 | = 5

| 4 - 8 | = | - 4 | = 4

| 5 - 8 | = | - 3 | = 3

| 6 - 8 | = | - 2 | = 2

| 6 - 8 | = | - 2 | = 2

| 8 - 8 | = | 0 | = 0

| 4 - 8 | = | - 4 | = 4

Finally find the mean of the absolute values

mean absolute value = $\frac{4+5+4+3+2+2+0+4}{8}$ = $\frac{24}{8}$ = 3

Answer 2

Answer:

1.25

Step-by-step explanation:

5-4=1

5-3=2

5-4=1

5-5=0

6-5=1

6-5=1

8-5=3

5-4=1

1+2+1+0+1+1+3+1=10

10÷8=1.25
