00:00

Thank you We sneak Then here's your smoke du jour

00:06

brought to you by various categorical data Oh sure Easy

00:11

for us to say All right which of the following

00:13

is an example of by various categorical data and hear

00:16

the potential answers No pizza You come and all right

00:22

here we go All right Well so this question is

00:24

really just testing to see if we understand the definitions

00:27

of by vary it and categorical data by very art

00:32

What is that Well let's Break it down Ever heard

00:35

about a bicycle or buying mary Well they have something

00:39

common by is a prefix That means to you know

00:42

like how a bicycle has two wheels or how the

00:44

binary number system uses zero in one one of two

00:47

options to express number So by vary it is a

00:51

word that describes two very couples B a r there

00:56

for characteristics of the sample in hand All right Categorical

01:00

categorical data describes data that measures some quality about an

01:04

individual something we can categorize but not with numbers In

01:09

other words quantitative data Now that we know what variant

01:12

in categorical means we can begin looking at our answer

01:15

Joyce starting with a pipe and a hair color Well

01:19

we have two variables but we usually measure height in

01:22

numbers so that wouldn't work So yes for you smarty

01:25

pants While sometimes we describe people as tall or short

01:28

or average we don't usually unless we're looking to pick

01:31

up quite yourself it would be super confusing if we

01:34

had twenty tall people because tall six foot person might

01:37

be short so it still doesn't work so cross on

01:41

right foot size sounds like only one variable you know

01:45

various data Besides imagine how gross it'd be to measure

01:49

all those basketball players feet after practice and just cross

01:52

off be thank you very much See plant pipe and

01:55

number of cucumber All they flat out told us We're

01:58

measuring with numbers that definitely using categorical data Uh pizza

02:03

topping and drink choice Well that's two variables and both

02:07

are categorical No numbers involved there It looks like our

02:10

answer but let's just check you to be extra sure

02:14

Our favorite magazine of librarians on ly one variable again

02:19

uh would not comment but these are answer And if

02:22

you asked us we'd choose hawaiian pizza with a good

02:24

root beer And then maybe in and cast plot a 00:02:28.411 --> [endTime] misfit
