gyakorisága

Gyakorisága is a Hungarian term that denotes the extent to which a particular event, attribute, or condition occurs within a defined population or dataset over a specified period. It is a foundational concept in statistics, epidemiology, linguistics, and social sciences, and it can refer to both absolute counts and relative measures such as proportions, percentages, or rates.

In epidemiology and public health, gyakoriság is often discussed in relation to prevalence and incidence. Prevalence describes the proportion of individuals in a population who have a condition at a certain point in time or over a designated period, while incidence refers to the number of new cases that develop during a specific interval. Beyond health, gyakoriság also appears as word frequency in language studies, event frequency in survey research, and occurrence rates in quality control and reliability analyses.

Measurement of gyakoriság can be expressed in several ways: as an absolute count, as a relative frequency (the count divided by the total number of observations), as a proportion or percentage, or as a rate per a defined population size (for example, per 1,000 or per 100,000 individuals). The choice of metric depends on the research question, the population under study, and the need for comparability across studies.

Common data sources include surveys, censuses, administrative records, clinical registries, and textual corpora. When interpreting gyakoriság, it is essential to specify the population, the time frame, and the method of data collection. Limitations such as sampling bias, underreporting, seasonality, and changing population denominators can affect the accuracy and comparability of frequency estimates.
