If we have time, we can discuss this in the session. If we don’t, feel free to wander off after today, and think about this before tomorrow. As an exercise, think of time series that you might be interested in. Emotion? Language? Brain waves? Any topic of interest to you is welcome here, even if it goes outside cognitive science a bit (though as mostly COGS students I imagine you’ll mostly be orbiting COGS in your thoughts).
When you think of the time series that interests you, think of the kind of data you might have. How might you get that data? What might it look like? When you have this image in your mind… try to classify the time series according to the three categories we discussed: categorical, continuous, or trial series.
Feel free to write your thoughts down in very brief form. We can come back to it tomorrow when we reconvene for more advanced methods.
Extra fun challenge: Today we analyzed the keystrokes CSV file. If you open this file in Notepad, you can see what such a data file looks like. You could create your own data file from something that is accessible on the internet. I’ll show you tons of examples tomorrow of places you can get data, but if you feel brave… go ahead and create a new file with your own data inside a CSV file in your working directory. (Important: Note that you do not need to have quotes around numbers, so you can simply copy/paste data from anywhere on the internet, load it up in RStudio, and plot it!)
