Here we have a stem and leaf plot, and we want to find the original set of data.
00:07
So what does the plot look like? so you have this here, and you have the stems.
00:13
So here, the stems go 1, 2, 3, and 4, and then coming out from them you have the leaves.
00:20
And these go in ascending order.
00:22
So from here we have a 0, a 1, and a 5.
00:26
From here we have 1, 4, 4, 7, 9.
00:31
From here we have 3, 5, 5, 5, 5, 7, 9, and here we have 0 at 1.
00:40
Okay, so even though i just had a list here, knowing it's a stem and leaf plot, i knew that i was looking at a pattern where we would start with the first stem, have some ascending numbers, and then stop and go down to a second stem, have some ascending numbers, go to a third stem, and so on.

So each of these, each of these represents one piece of data...
