WILL FAN & MEDAL HELP What is the meanstoMAD ratio of the two data sets, expressed as a decimal to the nearest tenth?
Data Set 1: {14, 18, 21, 15, 17}
Data Set 2: {15, 17, 22, 20, 16}

Best ResponseYou've already chosen the best response.1did you find the mean of both data sets yet ? (the average)

Best ResponseYou've already chosen the best response.0do you know how to find mad?

phi

Best ResponseYou've already chosen the best response.1for the mad, on data set 1, first find the median. that means sort the numbers, and find the "middle" number on the sorted list.

Best ResponseYou've already chosen the best response.0i got 17 and 18 for the mean

Best ResponseYou've already chosen the best response.1Let's just do data set 1. the mean is 17 I think the median is also 17: 14, 18, 21, 15, 17 becomes 14, 15, 17, 18, 21

Best ResponseYou've already chosen the best response.1notice 17 is the middle number after you sort the numbers small to big. to find the MAD, find the difference between the median and each number on the list. Always do bigger number minus smaller number (in other words, we want the absolute value) what new list of numbers do you get ?

phi

Best ResponseYou've already chosen the best response.1yes, the median is also 17. now subtract 17 from each number on the list and take the absolute value. what is the new list?

phi

Best ResponseYou've already chosen the best response.1yes, but we want all five numbers

phi

Best ResponseYou've already chosen the best response.1now find the average of those 5 numbers:

Best ResponseYou've already chosen the best response.03 + 1 +4 +2 +0 = 10 divde by 5 = 2

phi

Best ResponseYou've already chosen the best response.1yes, now we write the ratio of mean 17 to MAD 2 17/2 or 8.5 that is the "mean to MAD ratio" for data set1

phi

Best ResponseYou've already chosen the best response.1now we do data set2 the mean of data set 2 is 18 I think we can use the mean to find the MAD: subtract 18 from each number in data set2 and take the absolute value then find the average of those numbers to get the MAD

phi

Best ResponseYou've already chosen the best response.1ok, now what is the average of those?

phi
 one year ago
Best ResponseYou've already chosen the best response.1so the MAD is 2.4 the meantoMAD ratio is 18/2.4

phi

Best ResponseYou've already chosen the best response.1I think those are the answers: 8.5 for data set 1 and 7.5 for data set 2

Best ResponseYou've already chosen the best response.0i can only choose one answer

phi

Best ResponseYou've already chosen the best response.1I am assuming that each data set has its own meantoMAD ratio, so there are two answers (one for each data set) If there is only one answer, then I don't understand the problem. If your book or notes have an example of this type of problem, maybe I can figure it out.

Best ResponseYou've already chosen the best response.1my only other thought is to lump all the numbers together and find the average of all 10 numbers, and the MAD, and then the meantoMAD ratio.
