Probability Theory is the branch of mathematics that is concerned with the analysis of random phenomena or chance. Statistics is the science of making decisions under uncertainty.
Probability refers to the likelihood of an event occurring. It can be expressed as a number (0.5) or a percentage (50%). Statistical tests allow psychologists to work out the probability that their results could have occurred by chance, and in general psychologists use a probability level of 0.05.

The ratio of the number of equally likely outcomes in an event E E to the number of equally likely outcomes not in the event E ′ E ′ is called the odds for (or odds in favor of) the event. The opposite ratio (the number of outcomes not in the event to the number in the event E ′ E ′ to the number in the event E E is called the odds ...
Jul 18, 2023 · This is the frequentist definition of probability in a nutshell: flip a fair coin over and over again, and as N grows large (approaches infinity, denoted N→∞), the proportion of heads will converge to 50%.
Computing Odds. The ratio of the number of equally likely outcomes in an event E E to the number of equally likely outcomes not in the event E ′ E ′ is called the odds for (or odds in favor of) the event.
