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
