To find the median, order the numbers in the data set from least to greatest (or greatest to least, either one works) and then find the number in the middle. If there are 2 numbers in the middle, find their mean.
Step 1: Ordering the numbers.
<span>Original: 100, 88, 76, 78, 92, 94, 84, 98, 82, 90
Ordered: </span>76, 78, 82, 84, 88, 90, 92, 94, 98, 100
Step 2: Find the median (middle number).
The median is the number in the center.
Count in from each side equally to find the middle number.
76, 78, 82, 84, 88, 90, 92, 94, 98, <span>100
</span>78, 82, 84, 88, 90, 92, 94, 98
82, 84, 88, 90, 92, 94
84, 88, 90, 92
88, 90
88 and 90 are the middle numbers.
Since there are 2 numbers in the middle, we must find their mean.
Step 3: Find the mean of the 2 middle numbers.
Mean is also known as average.
To find this, add up the numbers and then divide by the amount of numbers there are.
In this case, that means adding 88 and 90 then dividing their sum by 2.
This can be represented by the equation (88 + 90) ÷ 2.
88 + 90 = 178
178 ÷ 2 = 89
89 is the final answer, it is the median.
Answer:
The median of this data set is 89.

Answer:
It should be 5:10 or 5 people not wearing sneakers and 10 not wearing a blue shirt
Step-by-step explanation:
Well it quite simple 1st you have the total which is 40
next you look at the rest, 15 people wearing sneakers plus the 5 waering sneakers and blue shirt. now you have 15.
next you have 10 people wearing but shirts. if you add the numbers you have now you get this: 15+10=25.
Now that you have 25 you can just add numbers to get 25(in that case 10 and 5). whats how you get 5:10
