    Choosing the correct analysis

    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!

    Re: Choosing the correct analysis

    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.
