OpenStudy (freeg13):
add all of them up then divide them by 5 because that is how numbers there are
OpenStudy (gabbyalicorn):
i did that i got 7 for the mean
l5-7l =2
l12-1l=11
l1-7l=6
l6-7l=1

what do you think the answer is @gabbyalicorn
OpenStudy (freeg13):
The steps to find the MAD include:
1. find the mean (average)
2. find the difference between each data value and the mean
3. take the absolute value of each difference
4. find the mean (average) of these differences
OpenStudy (gabbyalicorn):
i dont know 0.96 thats what i got when i did the mad
OpenStudy (gabbyalicorn):
i tried
OpenStudy (gabbyalicorn):

@satellite73
Mehek (mehek14):
the mean: 7
now tell me
7-5 =
12-7=
7-1=
7-6=
11-7=
OpenStudy (gabbyalicorn):
1. 2
2. 5
3. 6
4. 1
5. 4
OpenStudy (gabbyalicorn):
so 2 + 5 + 6 + 1 + 4 = 3.6 is this correct? @Mehek14
OpenStudy (gabbyalicorn):
