Question

The following dot plot represents the litter sizes of a random sample of labrador retrievers.

Calculate the mean, median, and mode for this set of data.
Calculate the range, interquartile range, and mean absolute deviation (rounded to the nearest hundredth) for this set of data. For the mean absolute deviation, do not round the mean.
Make two inferences about the litter size of labrador retrievers.

Answer 1

1. mean: 7.78 median: 8 mode: 7

2. range: 9 interquartile range: 2 MAD: 4.5367

3. The range is about 4 times bigger than the interquartile range. The mean is around double the MAD.

Step-by-step explanation:

Answer 2

12

Explanation:so the mean deviation is for the square and the square is for you so you keep the square and add it.
