SAS Beginer- Clarity required on the below

[Deepak13]

Hi,

Please explain what is the actual purpose of proc univariate and histogram codes in the below program, I have tired to find clarity in google but it lead to further confusions. Could anyone please explain this in simple words.

Many thanks.

Are you asking what a histogram is or what PROC UNIVARATE does?

[Deepak13]

I need to know why proc univariate is used in this code? and how histogram works in this code?

[Deepak13]

Yes @PeterClemmensen

Question via @PeterClemmensen 

Are you asking what a histogram is or what PROC UNIVARATE does?

@Deepak13 

Answer: Yes

That is not a yes/no question. Please take the time to provide clear information if you would like help, this is a volunteer user community.

To examine the distribution of the variable examgrade1.

Could you be more specific? how does it examine? If you don't mind explanation with a simpler program would do more good! @Reeza 

Many thanks.

[Reeza · Accepted solution]

Histogram - creates a histogram.

PROC UNIVARIATE is basically doing exploratory data analysis on data:
https://towardsdatascience.com/exploratory-data-analysis-8fc1cb20fd15

Why are you doing this? We can't know the answer to that, that's something you need to ask whoever told you to do this. If you're trying to learn statistics and SAS perhaps you should consider taking the first SAS Statistics course - it's online and on demand, and free.

https://support.sas.com/edu/schedules.html?ctry=us&crs=STAT1

You want to simplify three lines of code? I don't think that makes sense at all. The first set of the code is creating your data to analyze, that cannot be simplified.
