Need Help Running a Regression

[rstudionovice]

So I am running an experiment with three treatments. I want to see how the impact of an independent variable on the dependent variable and I want to run this for each treatment. What code could I use to do this?

To give you an example: I assigned people to watch three different news broadcast (three treatments) and then I wanted to see how their political affiliation would impact their feelings toward a policy issue. How would I run such a regression. I know the above example doesn't really make sense but basically three treatments, one specific independent variable and one specific dependent variable.

Hi Ashley, Welcome!

We don't really have enough info to help you out. Could you ask this with a minimal REPRoducible EXample (reprex)? A reprex makes it much easier for others to understand your issue and figure out how to help.

If you've never heard of a reprex before, you might want to start by reading this FAQ:

FAQ: How to do a minimal reproducible example ( reprex ) for beginners

A minimal reproducible example consists of the following items: A minimal dataset, necessary to reproduce the issue The minimal runnable code necessary to reproduce the issue, which can be run on the given dataset, and including the necessary information on the used packages. Let's quickly go over each one of these with examples: Minimal Dataset (Sample Data) You need to provide a data frame that is small enough to be (reasonably) pasted on a post, but big enough to reproduce your issue. Let's say, as an example, that you are working with the iris data frame head(iris) #> Sepal.Length Sepal.Width Petal.Length Petal.Width Species #> 1 5.1 3.5 1.4 0.…
