WILL FAN & MEDAL HELP What is the means-to-MAD 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}

  • phi
did you find the mean of both data sets yet ? (the average)
is3535
  • is3535
17 and 18

do you know how to find mad?
phi
  • phi
for the mad, on data set 1, first find the median. that means sort the numbers, and find the "middle" number on the sorted list.
is3535
  • is3535
i got 17 and 18 for the mean
phi
  • phi
Let'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
phi
  • phi
notice 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 ?
is3535
  • is3535
it the same
phi
  • phi
yes, the median is also 17. now subtract 17 from each number on the list and take the absolute value. what is the new list?
is3535
  • is3535
1. is 3 14 - 17 is 3
is3535
  • is3535
like that @phi
is3535
  • is3535
or no
phi
  • phi
yes, but we want all five numbers
is3535
  • is3535
18-17=1
is3535
  • is3535
21-17=4
is3535
  • is3535
17-15=2
is3535
  • is3535
17-17=0
is3535
  • is3535
im done
phi
  • phi
now find the average of those 5 numbers:
is3535
  • is3535
all the number are 3 1 4 2 and 0
phi
  • phi
yes, find the average
is3535
  • is3535
3 + 1 +4 +2 +0 = 10 divde by 5 = 2
phi
  • phi
yes, 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
is3535
  • is3535
now what
phi
  • phi
now 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
is3535
  • is3535
18-15=3
is3535
  • is3535
18-17=1
is3535
  • is3535
22=18=4
is3535
  • is3535
20-18=2
is3535
  • is3535
18-16=2
is3535
  • is3535
im done @phi
phi
  • phi
ok, now what is the average of those?
is3535
  • is3535
2.4
phi
  • phi
so the MAD is 2.4 the mean-to-MAD ratio is 18/2.4
is3535
  • is3535
7.5
phi
  • phi
I think those are the answers: 8.5 for data set 1 and 7.5 for data set 2
is3535
  • is3535
i can only choose one answer
is3535
  • is3535
@phi
is3535
  • is3535
i can only choose one answer
phi
  • phi
oh. what are the choices?
is3535
  • is3535
i have no choices
is3535
  • is3535
now what @phi
phi
  • phi
I am assuming that each data set has its own mean-to-MAD 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.
is3535
  • is3535
give me a sec
phi
  • phi
my only other thought is to lump all the numbers together and find the average of all 10 numbers, and the MAD, and then the mean-to-MAD ratio.
is3535
  • is3535
it its 7.5 two data sets, expressed as a decimal to the nearest tenth? two data sets
