Research direction

No repository file or test is named. Start by locating chapter 19 and reviewing how existing examples and labs are organized, then determine whether the proposed one-sample and paired-sample tests fit the chapter. Done would mean an agreed example is integrated with its accessible data and supporting lab materials.

Description

chp19

I always lament having to find real one-sample tests where the data are accessible.

Today, I found Natural behaviour is learned through dopamine-mediated reinforcement, which, brace yourselves, does left-tailed and right-tailed one-sample t-tests and a two-tailed paired-sample t-test all in one paper! (See Figure 2g)

I was able to write a fun lab that walks students through conducting a power analysis, collecting the data from the journal website (which seems deliberately annoying so I attached a .csv), visually summarizing the data, conducting resampling to assess whether a t-test is appropriate (n=25 < 30 < infinity), and actually performing the t-tests (effect sizes and confidence intervals, too). Doing all three tests gives them ample practice and enables them to compare and contrast across different test types.

We'll wrap up the semester learning to conduct bootstrap HT/CI and permutation HT/CI for a population mean, so these data will be able to follow the students through that.

Anyway, I thought I'd share because I often spend way too much time searching for these types of examples and I hope I can help someone save an hour or so. 8]
