Where is the 1st quartile in this data set?
36, 27, 15, 22, 33, 28, 43, 12, 33, 17

First of all, you have to rank the numbers from the lowest to the hightest. I let you to do it.

There are 10 numbers.

So, 0.25*10 = 2.5.

In that case, the 1st quartile would be the third number "17".

Hope this helps !

Iwould say they are complementary because that’s the division of a 90 degree angle and it’s split between the middle of them
