Answer 1

Answer:

5. Mean = 11.5

6. Median = 11

7. Range = 12

8. Mode = 9 and 11

9. Interquartile Range (IQR) = 5

10. Mean Absolute Deviation (MAD) = 2.8

11. Just Replace the Values just like the example image.

12. Just draw the min = 7 and max = 19 dot plot.

Step-by-step explanation:

Mean = (9+9+14+7+12+8+11+19+15+11)/10 = 115/10 = 11.5

Mean = 11.5

Median: 7,8,9,9,11,11,12,14,15,19

Median in the center = 11

Range: Big Number -  Small Number

Range = 19 - 7 = 12

Range = 12

Mode = 9 and 11

Interquartile Range (IQR): Q3 - Q1

Q3 = 14 , Q1 = 9

IQR = 14 - 9 = 5

IQR = 5

Mean Absolute Deviation (MAD): ( |7 - 11.5|+ |8 - 11.5| + ... + |15-11.5| + |19-11.5| )/10

MAD = ( 4.5 + 3.5 + 2.5 + 2.5 + 0.5 + 0.5 + 0.5 + 2.5 + 3.5 + 7.5 )/10 = 28/10 = 2.8

MAD = 2.8
