Recording the results of an experiment

Tallying the outcomes of repeated trials into a frequency table.

Relative frequency

The fraction of trials on which an event occurred, estimating its probability.

Estimating a probability from data

Relative frequency when outcomes are not equally likely, such as a drawing pin.

Predicting future results from relative frequency

Scaling an estimated probability up to future trials, rounded to a whole count.
