One of the most common research questions is do different groups have different mean scores on some variable? This question is best answered in 3 steps:

1. create a table showing mean scores per group -you'll probably want to include the frequencies and standard deviations as well;
2. create a chart showing mean scores per group;
3. run some statistical test -ANOVA in this case. However, this is only meaningful if your data are (roughly) a simple random sample from your target population.

We'll show the first 2 steps using an employee survey whose data are in bank-clean.sav. The screenshot below shows what these data basically look like.

Creating a Means Table

For creating a table showing means per category, we could mess around with Analyze Compare Means Means but its not worth the effort as the syntax is as simple as it gets. So let's just run it and inspect the result.

Note that you could easily add more statistics to the CELLS subcommand such as

• the median,
• skewness,
• kurtosis
• and many others.

Basically, our table tells us that the mean employee care ratings increase with higher job levels except for “upper management”. A proper descriptives table -always recommended- gives nicely detailed information. However, it's not very visual. So let's now run our chart.

SPSS Bar Chart Menu & Dialogs

As a rule of thumb, I create all charts from Graphs Legacy Dialogs and avoid the Chart Builder whenever I can -which is pretty much always unless I need a stacked bar chart with percentages.

In the dialog shown below, selecting Other statistic... enables you to enter a dependent variable;

Basic Bar Chart Means by Category Syntax

Result

We now have our basic chart but it doesn't look too good.From SPSS version 25 onwards, it will look somewhat better. However, see New Charts in SPSS 25 - How Good Are They Really? Yet. We'll fix this by setting a chart template: bar-chart-means-trans-720-1.sgt.

Note that a chart template can also sort this bar chart -for instance by descending means- but we'll skip that for now.

Bar Chart Means by Category Syntax II

Result

Right, so that's about it. If you need a couple of similar charts, you could copy-paste-edit the last GRAPH command (no need to repeat the other commands). If you need many similar charts, you could loop over the GRAPH command with Python for SPSS.

If you're going to run other types of charts, don't forget to set a different chart template. Or switch if off altogether by running set ctemplate none.
