Midterm Review
- Random variable: a function that maps each outcome of a random experiment to
. Note that the experiment is random, but is deterministic. - Support: another way of saying "sample space" or "range of random variable
" - PMF: since we're dealing with discrete distributions, the PMF is literally just the function that determines the probability of
occurring, based on the distribution. - Expected value: literally just the mean of the outcomes of an experiment
- Variance: how far
is from the mean. .
