To find the median of a set of numbers write them in order, then: * if there are an odd number of numbers then the median is the number in the middle * otherwise there are an even number of numbers and the median is the mean average of the two numbers in the middle. With 4 numbers there is an even number of numbers, so the median is the mean average of the 2nd and 3rd numbers when they are sorted into order. Example: Find median of {3, 9, 4, 5} Ordered → {3, 4, 5, 9} → median = mean_average(4, 5) = (4 + 5) ÷ 2 = 4.5
As there are 6 numbers, the median is half way between the middle numbers, or (7+9) / 2 = 8
Put the numbers in order. The odd one in the middle is the median: 1,2,3,4,5,6,7 (4 is the median). If even numbers, it is between the two middle numbers: 1,2,3,4,5,6,7,8 (between 4 and 5 is the median).
The median of a set of numbers is the middle one (if there are an odd number of them) or the mean average of the middle two (if there are an even number of them). The dataset {4, 4, 5, 5, 6, 6, 7, 7, 8, 8, 8, 9, 10, 11} has 14 elements, so the median is the mean average of the 7th and 8th numbers. The 7th and 8th numbers are 7 and 7, thus the median is (7 + 7) / 2 = 7.
Here's an example question so I can better explain this. Say you get a worksheet that says "Find the median of 10, 7, 4, 3, 16 and 10." First you would arrange these numbers in numerical order, starting with the lowest. This would give you: 3, 4, 7, 10, 10, 16, 20 Cover 3 and 20 with two of your fingers. Then move inward, covering 4 and 16. Next you'd cover 7 and 10, leaving 10 in the middle. 10 is the median of these numbers. Here's another example. "Find the median of 7, 9, 3, 5, 8 and 1." 1, 3, 5, 7, 8, 9 Using the method above, there are two numbers left in the middle: 5 and 7. When there are two numbers left over, the median is in the middle of these. The median for the above sequence is 6.

The 5 numbers 4 + 5 + 8 + 8 + 10 = 35 then divide by that 5 to give 7 as the mean average. The median is the middle value which is 8.
The median is the "middle" so put them in order first.1, 4, 5, 9, 10, 15You will notice that you have an even amount of numbers and surely will have two medians: 5 and 9. Find their average and the median of this set in 7.

As there are 6 numbers, the median is half way between the middle numbers, or (7+9) / 2 = 8
To find the median of the numbers 4, 5, 7, 9, 10, and 12, you have to list the numbers from least to greatest and then find the middle number. So if you count them out or cross 1 number from each side, (4-12, 5-10) you're left with 7-9 as middle numbers / center numbers. Because the middle numberS is 7 and 9, you have to find what's between it to find the median. And we all know between 7 and 9, there is 8. So 8 is your median.
Put the numbers in order. The odd one in the middle is the median: 1,2,3,4,5,6,7 (4 is the median). If even numbers, it is between the two middle numbers: 1,2,3,4,5,6,7,8 (between 4 and 5 is the median).
