About the lecture

In this lecture, we think about types of statistical test, focusing in particular on: (i) the t-test as a common test type for comparing differences between two groups, wherein the test converts scores to a t-value which can be compared to a critical value to assess whether the difference is significant; (ii) a Pearson’s correlation or a Spearman’s Rho as methods of testing the likelihood that two factors co-occur, the former assumes the link is linear, while the latter does not; (iii) the Chi Square test as a method of testing whether percentages or proportions of certain events are within the realm of random chance.
