Question

Find the median of the collection of numbers: 3, 1, 9, 5, 9, 6, 9

Answer 1

median=in the middle right

Answer 2

Firs, rearrange the numbers from smallest to largest
\(3, 1, 9, 5, 9, 6, 9\)

Becomes
\(1, 3, 5, 6, 9, 9, 9\)

Now find the median. This is the middle number. An easy way to find out is to do:
\[Median=\frac{n+1}{2}\]
This will give where the median is located. \(n\) is the total numbers. Here, it is 7
\[Median=\frac{n+1}{2}\]\[Median=\frac{7+1}{2}\]\[Median=\frac{8}{2}\]\[Median=4th\]

Now you know the median is the \(4th\) number. Note, this will NOT give you the actual median, just where it is located. Now we know that its the fourth number, look for that
\(1, 3, 5, 6, 9, 9, 9\)
\(1, 3, 5, \color{red}{\Huge{6}}, 9, 9, 9\)

So the median is the 4th number, which is 6

Answer 3

Does that make sense, @omg1help?

Answer 4

yes

Answer 5

You could always just look for the middle number instead of doing the equation. The equation is helpful when you have a huge list of numbers, or its an even total
