... There are two types of t-tests. A dependent, or correlated, t-test is used when the difference between the means of the same group assessed on two occasions is being evaluated (e.g., pre-post). An independent, or uncorrelated, t-test is used when the difference between the means of two separate gro ...

... E.g. with a discrete random variable like tossing a die, it is meaningful to talk about P(X=5), say. In a continuous setting (e.g. with time as a random variable), the probability the random variable of interest, say task length, takes exactly 5 minutes is infinitesimally small, hence P(X=5) = 0. It ...
