in this video i’ll show you how to make
quick histograms in stata
histograms can be used to describe the
distribution of a variable
this is an example of a histogram
it describes the distribution of
internet usage in a sample of countries
the histogram shows that
low internet usage countries are very
prevalent
over 30 percent of the sample has little
to no internet users
it shows that high internet usage is
less common
if you compare the bars on the right
with the left you’ll see that a very
small proportion of the sample has 60 or
more internet users per 100 people
to create quick histograms we use the
command hist
short for histogram
the syntax for creating a histogram is
hist
space
the name of the variable
comma and then your options
in this example
i’m using
net users which is a variable that
describes the distribution of internet
usage
the percent option
tells data to create a histogram with
particular features
there are many different options
Command: Options
available in creating quick histograms
in stata
we use the
option discrete if we’re using discrete
instead of continuous variables
frac
freak
and percent
tells data which y-axis scale to use
frac expresses the y axis as decimal
functions
freak describes it as frequencies
and percent gives it as a percent of the
sample
let’s see what it’s like to produce a
quick histogram and a real status
session
his sei
will give me a histogram of the variable
sei which is the samples socioeconomic
index
that’s how the variable is distributed
for discrete variables like degree
use the option discrete
it makes the bars fatter
let’s review
Review
