And here's your shmoop du jour brought to you by

00:06

science fair the only place you'll find more volcanoes than the Hawaiian island [Kids with volcanoes at a science fair]

00:10

all right if we create a dot plot for the ages of students who entered the tri

00:15

state science fair its shape would be most similar to that of the what? ..And

00:20

here the potential answers and they're right here... All right this question is asking [Man sat by a grave filled with dots]

00:27

about dot plot which is not where we bury our theater candy after its died

00:32

really we're just being tested to see if we know what one of these things look [A dot plot with a question mark]

00:36

like in action although we also need to know what these other things look like

00:40

because well we need to track down it's twin and without going on ancestry.com [man on a computer looking on ancestry.com]

00:45

that'd be cheating. The dot plot is you might guess if you didn't already know

00:48

it's made up of dots, but don't get it confused with a scatter plot a dot plot [A dot plot below a scatter plot]

00:54

displays graphical data like this where a series of results are presented in

00:58

random order in that they aren't sorted from high to low or from low to high so

01:03

great we can cross off scatter plot, oh wasn't one of the choices, aint that a kick [Girl draws a line through scatter plot and is kicked away]

01:08

in the pants. Well alright what are other choices well first up is cumulative

01:12

frequency histogram which is one of these babies it's sort of resembles a

01:17

dot plot except as a value shown in a cumulative frequency histogram will [A frequency histogram plot]

01:21

always increase from left to right so the histogram is history! What about

01:26

B pie chart. A dot plot has about as much in common with a pie chart [Man in the shower fully clothed]

01:31

as our singing voice has with Beyonce's to be fair, our shower has really...

01:36

all right then there's C stem and leaf plot, the word plot is in there but

01:42

that's where the similarities end here we have rows instead of column values [A row on a stem and leaf plot circled]

01:47

instead of dots, so nah we can leave C alone. Our graph does look a bit

01:52

like a bar graph but bar graphs are used more for showing categorical data like [A bar graph example]

01:58

the names of U.S. Presidents and the number of assassination attempts each had [Lincoln sat in a chair]

02:02

Yeah, that's a grim example, sorry but with a frequency histogram not the cumulative

02:08

kind you're looking at continuous data where you can have all kinds of random

02:12

data points that don't necessarily fit into distinct categories. So D

02:16

is our answer which reminds us of the D we got on our science project who knew [Boy holding up a piece of paper with a grade D]

02:21

dropping potassium in water would be so er, explosive oh you all knew that [Boy drops potassium in water and flames appear]

02:27

where were you when we needed you
