ANOVAs

Setting up

To practice with ANOVA, we will use a selection of my data on word recognition. Let’s open it first. In this dataset, each participant saw a number of words from one frequency range only. Participants were asked to press a response button when they saw a word they recognize.

library(tidyverse) # what would we do without it?

_________ <- ______________ # we are not expert of read_csv() aren't we?

Let’s have a look. What’s the format? It is okay to run an ANOVA?

One-way ANOVA

Let’s build an ANOVA model to see if response time (RT) is predicted by frequency:

model <- ___(__ ~ _______, data=_______) # we should name it so to call it

model # like this

______(model) # let's see what the model says and let's interpret the ANOVA table together.

What does the model tell us? What’s the the interpretation of the results?
