Zatrzymanie pobierania danych następuje zgodnie z predefiniowaną obserwacji. W odróżnieniu od niezaplanowanego „podglądania danych”, które jest nadużyciem metodologicznym, i podwyższa ryzyko błędnego uznania fałszywej hipotezy za prawdziwą (popełnienia błędu I rodzaju), analiza sekwencyjna uwzględnia poprawki na wielokrotne testowanie danych, dzięki czemu kontroluje błąd I rodzaju na nominalnym poziomie istotności. Analiza sekwencyjna – technika statystyczna pozwalająca realizować badanie etapowo, i przerwać je gdy tylko jedna z wykaże, że zebrane do tego momentu wyniki wystarczają do potwierdzenia hipotezy badawczej.Thus a conclusion may sometimes be reached at a much earlier stage than would be possible with more classical hypothesis testing or estimation, at consequently lower financial and/or human cost. Instead data are evaluated as they are collected, and further sampling is stopped in accordance with a pre-defined stopping rule as soon as significant results are observed. In statistics, sequential analysis or sequential hypothesis testing is statistical analysis where the sample size is not fixed in advance.* Portail des probabilités et de la statistique (fr) Ainsi, une conclusion peut parfois être atteinte à un stade beaucoup plus précoce que ce qui serait possible avec des tests d'hypothèse ou des estimations plus classiques, à un coût financier ou humain par conséquent inférieur. Plutôt, les données sont évaluées au fur et à mesure qu'elles sont recueillies, et l'échantillonnage est arrêté selon une règle d'arrêt prédéfinie, dès que des résultats significatifs sont observés. En statistique, l'analyse séquentielle ou le test d'hypothèse séquentiel est une analyse statistique où la taille de l'échantillon n'est pas fixée à l'avance.Wijsman RA (1967) General proof of termination with probability one of invariant sequential probability ratio tests based on multivariate normal observations.
