univariate data a la shmoop. sometimes so much can be communicated by

00:09

a single word. just be sure there's actually a fire. all right well in math [man and woman watch sunset]

00:14

we have a term for that. univariate data. unit as in one. and variate as in

00:20

variable. it's a good way of keeping things simple and uncomplicated so we

00:25

can examine a single type of data and compare it to other data. so for example

00:30

say someone conducted an experiment in which they tried to balance a bunch of

00:33

different items on different body parts for varying lengths of time while

00:37

standing in different positions. well there are a few balls in the air here. [man juggles large objects]

00:42

rather than worried about our guy balancing a lit grill on his right

00:46

shoulder for 20 minutes while standing on one leg we can instead zero in on the

00:50

item he's balancing .but we're really just looking at a list. it might read

00:54

holding chair teapot book show flat-screen television panda bear, and so

00:59

on. if you're dealing with chemicals that react with one another in a certain [list of household items]

01:03

temperature well you're gonna focus just on the types of chemicals or just on the

01:07

temperature but not both. either way please try to keep some focus

01:11

on the actual chemicals .and don't forget where the eyewash station is. okay if you

01:16

get a handle on things and want to go a level deeper there's always bivariate

01:20

data. now you can start bringing in a second variable into the mix here. if

01:24

you're looking at men and women of different ages who graduated from [person stirs vegetables in a frying pan]

01:28

various Clown colleges, well now you can track both the ages of the people and

01:32

the prestigious Clown colleges they attended. but bivariate data is a

01:38

different story for a different day. let's not get ahead of ourselves. so for

01:41

now slow down enjoy life and try to maintain some talent. [juggling man is knocked down by bear]
