Definitions:

Significance Level

In statistical hypothesis testing, it's the probability of rejecting the null hypothesis when it is actually true, often represented by the symbol alpha (α).

Multinomial Experiment

An experiment that meets the criteria where each trial results in one outcome from a set of three or more possible outcomes.

Observed Frequencies

The count of occurrences or instances actually measured in a dataset or study.

Significance Level

The threshold of probability below which the null hypothesis is rejected in hypothesis testing.
