Njira Zowerengera mu Biology Kugwiritsa ntchito njira zowerengera mu biology kwasintha momwe asayansi amamvetsetsera zochitika zosiyanasiyana zachilengedwe. Ziwerengero zimathandiza kuwerengera deta kovuta, kuzindikira njira, ndikupeza ubale pakati pa zinthu zomwe sizikugwirizana. Nkhaniyi ifotokoza njira zosiyanasiyana zowerengera zomwe zimagwiritsidwa ntchito mu biology ndikufotokozera momwe zimagwiritsidwira ntchito kuthetsa mavuto a biology. … Werengani zambiri
Kusanthula kwa Zoyambira za Covariance Kusanthula kwa Covariance (ANCOVA) ndi njira yowerengera yomwe imaphatikiza njira zowongolera ndi kusanthula kusiyana (ANOVA) kuti ziwongolere zosintha zomwe zingakhudze kusintha kodalira. Cholinga chachikulu ndikuwunika momwe zosintha zodziyimira pawokha zimakhudzira kusintha kodalira pambuyo powongolera zotsatira za zosintha zomwe zimadziwika kuti covariates.

Ziwerengero mu Kusanthula Zachuma Chiyambi Ziwerengero ndi sayansi yosonkhanitsa, kusanthula, kutanthauzira, kupereka, ndi kukonza deta. Mu dziko la bizinesi ndi zachuma, ziwerengero zimagwira ntchito yofunika kwambiri, zomwe zimathandiza akatswiri, osunga ndalama, ndi oyang'anira kupanga zisankho zozikidwa pa deta. Popanda kusanthula kwakuya kwa ziwerengero, zisankho zachuma zimakhala zongoganizira chabe komanso zoopsa kwambiri. … Werengani zambiri
Mayeso a Mann-Whitney mu Statistics Statistics ndi nthambi ya masamu yokhudzana ndi kusonkhanitsa, kusanthula, kutanthauzira, ndi kupereka deta. Ziwerengero zimagwiritsidwa ntchito m'magawo osiyanasiyana popanga zisankho zozikidwa pa deta. Njira imodzi yomwe imagwiritsidwa ntchito kwambiri mu ziwerengero ndi Mayeso a Mann-Whitney (omwe amadziwikanso kuti Mayeso a Mann-Whitney U kapena Mayeso a Wilcoxon Rank-Sum).
