Choosing the correct analysis


New Member
Hi everyone,

Really needing help with choosing the right analysis for my variables.

Background: I'm looking at the difference in amplitude for reaction times of negative, positive, and neutral words.

The IV: reaction times (negative, positive, neutral words)
The DV: amplitude

BOTH variables are continuous. I want to see where the difference in amplitude lies (between positive, negative, and neutral words). I want to do a 2-way ANOVA but the reaction time variable has to be categorical and I'm not sure how to convert it!!

Any help would be appreciated!

Thank you!


Less is more. Stay pure. Stay poor.
If you are just examining amplitude vs word type, why can't you just do: amplitude = word type dummy coded. You could even control for reaction time if that was applicable.

amplitude = positive + Neutral + reaction time, where negative is your base case.
