Answer:
Median=78 Q1=66 Q3=85.5
Explanation:
Median
Make sure the values are in order before you start The median is the number straight in the middle. Start by crossing off the same amount of numbers from the end and the beginning.
Like this: 32, 55, 61, 62, 64, 64, 64, 68, 73, 75, 76, 77, 78, 78, 79, 79, 80, 82, 83, 85, 86, 88, 90, 92, 93, 85, 98
I crossed off 10 numbers starting from each end now you keep going untill you have the middle number.
Like this: 32, 55, 61, 62, 64, 64, 64, 68, 73, 75, 76, 77, 78, 78, 79, 79, 80, 82, 83, 85, 86, 88, 90, 92, 93, 85, 98
I crossed out 3 more numbers now and 78 was the number in the middle.
Now for Q1
It's the same as the median but you need the median first because you go off of it. For Q1 you get the median and all the numbers BEFORE it and you do the same thing you did to find the median.
Like this: These are all the numbers before and including the median.
32, 55, 61, 62, 64, 64, 64, 68, 73, 75, 76, 77, 78, 78
Now because there isn't a number in between 64 and 68 in this data set, you have to find the one on the number line. 66 is the number EXACTLY in between 64 and 68. So 66 is the Q1.
Q3
So you do the same thing that you did for Q1 but you do all the numbers including the median and AFTER the median
Like this: 78, 79, 79, 80, 82, 83, 85, 86, 88, 90, 92, 93, 85, 98
In between 85 and 86 is 85.5. 85.5 is the Q3.
