Key Concepts

Proportions and Extrapolation

Proportions involve comparing a part to a whole, often expressed as a fraction or ratio. Extrapolation uses the ratio derived from a sample to predict values in a larger population. By maintaining the same ratio observed in a smaller set, we can estimate outcomes for a larger group, assuming the sample is representative.

Experimental Probability

Experimental probability refers to the estimation of the likelihood of an event based on the data obtained from an experiment or survey. It is calculated by dividing the number of times an event occurs by the total number of trials or observations. This method is particularly useful when theoretical probabilities are difficult to determine, as it relies on actual observed outcomes.
