Abby's MAD is 45 and her IQR is 51.5. Caleb's MAD is 28 and his IQR is 16. The coach should choose Caleb.
MAD
Simply calculate the mean (average) of all the data and find the maximum deviation. Make sure you look at data both larger and smaller than the mean. e.g. Abby:
(146+147+178+231+195+209+207+219+187)/9 = 191
The data with the largest deviation from the mean is 146, so 191-146=45
IQR
To compute the quartiles, the data must be put into ascending order of value. I will use Caleb's data set as an example; please see the photo for details.
Therefore, because both Caleb's MAD and his IQR are lower than those of Abby, the coach should choose him.

Answer:
11/15 is greater
Step-by-step explanation:
Probability is the extent to which an event is likely to occur. It is the likelihood of sth to happen.
In maths it is measured by the ratio of the favourable cases to the whole number of cases possible.
For instance
there are 5 black balls and 2 white balls of same shape and size.
If you picked one out of a bag it is more likely for you to pick a black one rather than a white one as it has more in number.
So black balls have more probability.
And to find out probability of this above given event,
Sample space n(S) = 5+2 = 7
No. Of black balls n(B) = 5
No. Of white balls n(W) = 2
Probability of black ball p(B) = n(B)/n(S)
=5/7
And in the same way, p(W) = 2/7
