Question

I need help on Number 1 and number 2

Answer 1

How to find the MAD:
       1) Add all numbers
       2) divide by a number of numbers given
       3) if told, round
1. The mean absolute deviation of a set of data is the average distance between each data value and the mean. The mean number of contacts stored and the distance each data value is from the mean is shown below. Each data value is represented by an ×.
the mean MAD is 129.4. rounded, it will be 129.

2. splash of lagoon: 89.6 rounded is 90
wild water bay: 116.6 rounded is 117
The height of the waterslides at splash lagoon varied less than the height of the water slides at wild water bay. The waterslides at wild water bay varied more probably because they overall were taller waterslides.
