Calculate Expected Frequency: Easy Guide & Formula

In various fields, anticipating how often specific events or outcomes should occur under particular circumstances involves comparing observed data with theoretical probabilities. For instance, in genetics, researchers might compare the observed distribution of genotypes within a population to the distribution predicted by Mendelian inheritance. This comparison helps identify deviations and potential influencing factors. A chi-squared test is a common statistical method employed in such analyses.

Such predictive analyses are fundamental to numerous disciplines, including genetics, statistics, epidemiology, and market research. These projections provide a baseline for evaluating observed data, enabling researchers to identify unexpected variations and potentially uncover underlying causes or influencing factors. Historically, the ability to make these kinds of predictions has revolutionized fields like epidemiology, allowing for more targeted public health interventions.
