 Let's consider a situation where you are testing the effect of alcohol consumption on simple reaction time (e.g., press a button as fast as you can after a light appears). To keep it simple, let's assume that you have collected data from 14 participants randomly assigned to perform a set of 10 simple RT trials after one of two interventions: drinking a pint of alcohol (treatment condition) or a placebo drink (placebo condition).  You have 7 participants in each of the two groups. Note that you would need more than this for a real study.

 If we were going to run a t-test on these data, we would first need to calculate subject means, because otherwise the observations are not independent. You could do this as follows. (If you want to run the code below, you can download sample data from the web app above and save it as `independent_samples.csv`).

 ## Simulating data with crossed random factors
 
-For these exercises, we will generate simulated data corresponding to an experiment with a single, two-level factor (independent variable) that is within-subjects and between-items.  Let's imagine that the experiment involves lexical decisions to a set of words (e.g., is "PINT" a word or nonword?), and the dependent variable is response time (in milliseconds), and the independent variable is word type (noun vs verb).  We want to treat both subjects and words as random factors (so that we can generalize to the population of events where subjects encounter words).  You can play around with the web app (or [click here to open it in a new window](https://shiny.psy.gla.ac.uk/Dale/crossed){target="_blank"}), which allows you to manipulate the data-generating parameters and see their effect on the data.

 You can look up any bivariate correlation at the intersection of any given row or column. So the correlation between `height` and `mass` is .134, which you can find in row 1, column 2 or row 2, column 1; the values are the same. Note that there are only `choose(3, 2)` = 3 unique bivariate relationships, but each appears twice in the table. We might want to show only the unique pairs. We can do this by appending `corrr::shave()` to our pipeline.

 Now we've only got the lower triangle of the correlation matrix, but the `NA` values are ugly and so are the leading zeroes. The **`corrr`** package also provides the `fashion()` function that cleans things up (see `?corrr::fashion` for more options).
