In this tutorial we’ll look at how to
construct a Bar Graph in SPSS. And here we have the variable car color where we
have 15 different cars that were observed as people drove by someone
noted the color of the car and what I’ve done in this example is I’ve already
entered my value labels. So for example if I click on this button
right up here then I’ll see the colors that the different numbers correspond to. So notice we have one, two, three, four
white cars were observed and so forth. I’m going to turn these off for now but
you’ll see how they’re very useful in just a moment when we produce our Bar
Graph. To produce a bar graph let’s go to Analyze and then Descriptive Statistics
and we can actually use the Frequencies command to produce a Bar Graph and then
we can also use the Graphs I’ll show you both ways. So we’ll start with this
Analyze, Descriptive Statistics, Frequencies and then here I’m going to –
you should see your window look like this – I’m going to move car color over to the
Variables box. Select Charts and then here we want to select a Bar Charts. Click
Continue. Let’s de-select the Display
frequency tables and then click OK. And notice here in this case we get a Bar
Chart where the variable is car_color on the X-axis the frequency is on the Y-
axis we have our different car colors here and and the height of the bar
indicates the frequency or how many of each color car was observed. So we have two black cars were observed
for white cars, six blue cars, two red cars, and one green car. Now many of the options on this chart
can be modified and I’ll show you one quick modification we can make. If I
double-click on this chart what will happen is the Chart Editor
will open as you see here and I’m going to double click on any of these bars. And
when I do that the Properties dialog box opens. Let’s go ahead and go to Fill & Border.
Click on that tab and then I’ll select this blue color right here and then
click Apply and close this out. Notice what happened here now my bars
are blue. This is one of the many options that can be modified in our charts. Let’s go ahead and close this out so
click X and then now we have our chart and notice the blue color has been
applied. As I said at the beginning I was going to show you how to obtain this
exact same chart using the Graphs menu command. So let’s go to Graphs. Go to Legacy
Dialogs and then go to Bar. Now here a Bar charts dialog box opens and I want
to leave the Simple and Summaries for groups of cases default options in place.
So just click Define. And then here what we want to do, you should see a
window like this with car color on the left, go ahead and move that to the Category Axis box
and then click OK. And you should see that this gives us the exact same bar
chart with the only exception is that I haven’t modified the color to be blue
and I won’t do that now but you saw how to do that so I think
you could do that as well. OK so we saw how to obtain a bar chart using two
different approaches. Both the Frequencies procedure and using the
Graphs Legacy Dialogs command. This concludes the tutorial on obtaining
a bar chart in SPSS.
