IQR
how do you find the IQR from a set of numbers?
1) put the #s in order form least to greatest 2) find the median 3) find Q1 and Q3 4) subtract Q3 and Q1
Find the IQR, range, median, mode, and MAD.
13.5, 15.9, 30, 10.6, 10.5, 9.5, 15.1, 13.9,
(yes, again order least to greatest DONT FORGET)
IQR : 4.95
Range : 20.5
Median : 13.7
Mean : 14.875
Mad : 4.09375
What is the median?
The middle number
what is the mean?
The average of the amount of values
How do you find the MAD?
To find the Mean Absolute Deviation (MAD), first calculate the mean (average) of your data set. Next, find the absolute difference (distance) between each data point and the mean. Sum up these absolute differences, and finally, divide that sum by the total number of data points to find the MAD.
Find the IQR
7, 8, 1, 0, 0, 3, 2, 10, 11
(and yes order least to greatest)
The IQR is 8.5
How do you find the median?
Order the values least to greatest and find the middle
Mean : 28.5
8.5+1.5+15.5+15.5+8.5+49.5=99
The MAD is 99
Find the IQR
0, 7, 4, 2, 2, 10, 47, 94, 36
The IQR is 39.5
What is the median of the data set?
3, 7, 4, 8, 5, 10, 19,
The median is 7
What is the IQR?
6.7, 2.8, 30, 47, 3.5, 2.2
The IQR is 27.2
Find the IQR
102, 150, 259, 269.99
The IQR is 138.495
