00:01 All this, the mode, now it wants to know the first and the third quartile.

00:03 So that means that you're going to have to put these numbers in order from least to greatest.

00:09 So let's figure out the smallest number i'm going to go with is probably 36.

00:22 Then i have 37, 38, 39, 40, 41, 42, 43, 45, 46, 47, 48, 49, 50.

00:43 Okay, so 39, 45, 39, 45, 48, 48, 45, 48, 43, 44, 34, 37, 37, 41, 41, 45, 45, 44, 40, 44, 47, 40, 41, 45, 40, 44, 40, 44, 45, 45, 40, 45, 40, 48, 4047, 41, 48, 39, 41, 42, 42, 41, 42, 41, 41, 40 and 40, 54, 42, 41, 39, 41, 39, 48, 42, 434, 48, 42, 434, 64, 60, 36, 39, 38, 42, 43, 44, 60, 60, 36, 39, 38, 42, and 43, and 34, 60, and, okay, so now i need to find the first and the third quartile.

02:37 So i know that the median is going to be 42.

02:42 So hold on.

02:43 Let me change my color.

02:46 Okay.

02:47 So i didn't have a 46, it appears.

02:54 Let me just double check that.

03:00 So i didn't have a 46.

03:01 I didn't have a 49.

03:03 So i have 1, 2, 3, 4, 5, 6, 7, 8, 9, 10.

03:08 11, 12, 13, 14, 15, 16, 21, 26, 27, 28, 29, 30, 31, 36, 37, 38, 39, 40.

03:21 Okay, so there was 40 altogether.

03:24 So now i'm going to count in 20.

03:25 So 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 15, 16, 17, 18, 19, 20...
