How to bin my data?

[#1]

So in my data set I have 4 conditions that I am testing against a variety of variables. We can call these conditions 1, 2, 3, 4. My conditions are nominal. So when I visualize my graphs I will plot conditions (x-axis) against, let's say, a time variable. What I would like to do is instead of comparing my 4 conditions, I want to combine/group some and compare against each other. For example, group conditions 1 and 2 data and compare 1+2 against 3+4. So basically instead of having 4 bars on my x-axis (representing all 4 conditions) I will have 2 (representing two combined conditions). I hope this makes sense. I do not have a lot of experience in jmp or statistics in general and I am stuck!

Hi sgulas25

One way to do this is by recoding the levels of your nominal factor. First select the column with your conditions, then go to the Cols menu and select "Recode."  Recode will show you the original levels of your variable on the left, and has a space to enter their new values on the right, Enter in whatever labels you want for your levels, and since you want to combine levels you will be entering in the same value for 1/2 and 3/4. Before clicking OK I would suggest changing "In Place" to "New Column" so you get a new column with your recoded values rather than overwriting the original values.  With your new column that combines your original levels you can analyze and visualize 1/2 and 3/4 as groups.

I hope this helps!
