What is computing relative frequency from a results table?Show answer
Most exam data arrives as a frequency table. The method is always the same three steps:
What is relative frequency as experimental probability?Show answer
When the outcomes are not equally likely, or you simply have no theory to work from - a drawing pin landing point-up, a basketballer sinking a free throw, a household owning a pet - you cannot compute a theoretical probability. So you estimate it from data. The relative frequency you measure is taken as the probability:
