test jednostronny/dwustronny Explanation: Piotr Bienkowski asymmetrical test ; one-sided test ; one-tailed test ; single tail test test niesymetryczny ; test jednostronny ; test jednowymiarowy https://www.proz.com/personal-glossaries/entry/14444074-asym... two-sided test ; double-tailed test ; two-tailed test test dwustronny ; test podwójnie odwrócony https://www.proz.com/personal-glossaries/entry/14452213-two-... cccccc One- and two-tailed tests In statistical significance testing, a one-tailed test and a two-tailed test are alternative ways of computing the statistical significance of a parameter inferred from a data set, in terms of a test statistic. A two-tailed test is appropriate if the estimated value may be more than or less than the reference value, for example, whether a test taker may score above or below the historical average. A one-tailed test is appropriate if the estimated value may depart from the reference value in only one direction, for example, whether a machine produces more than one-percent defective products. Alternative names are one-sided and two-sided tests; the terminology "tail" is used because the extreme portions of distributions, where observations lead to rejection of the null hypothesis, are small and often "tail off" toward zero as in the normal distribution or "bell curve", pictured on the right. https://en.wikipedia.org/wiki/One-_and_two-tailed_tests |
