Inferential Statistics are used to make judgements of the probability by performing tests, using probability distributions, correlations and functions. Probability of an event is the likelihood of the event that occurs at-least once. Distributions are generalized functions of classical notion in mathematical statistics. Correlation show how well the variables are related. A relation between a set of inputs and a set of permissible outputs (each input is related to exactly one output) is referred to as a function.
Listed here are various inferential statistics calculators (probability and statistics) for calculating the probability, distribution, correlations, function etc.
