Answer: The answer to 2, 6, 12, 16 is 9 and the answer to 5, 6, 12, 13 is 9
Step-by-step explanation: The mean of a set of numbers is another term for average. You add all of the numbers up like for example in the second set of numbers, 16+12+6+2 is equal to 36 and you then divide that sum by the amount of numbers you added which in this case is 4 so you get 36/4 which is equal to 9.
Using cross multiplication,
30 x 14 = 20 x w
so
w = 420/20
w = 21
The mean absolute deviation of the given scores of Robin as shown in the diagram atatched is: 5.2.
<h3>What is the Mean Absolute Deviation of a Data?</h3>
The mean absolute deviation of a data set is determined by finding the average of the distance of each data point from the mean of the data set.
Given that the distance from the mean are: 8, 1, 5, 0, 12,
Mean absolute deviation = (8 + 1 + 5 + 0 + 12)/5
Mean absolute deviation = 26/5
Mean absolute deviation = 5.2.
