A student factors 3x2 - 12 to the following. 3(x2 - 4)Which statement about 3(x2 - 4) is true? In statistics the t-distribution was first derived as a posterior distribution in 1876 by Helmert and Lüroth. The t-distribution also appeared in a more general form as Pearson Type IV distribution in Karl Pearson's 1895 paper.. In the English-language literature the distribution takes its name from William Sealy Gosset's 1908 paper in Biometrika under the pseudonym " Student ".

A simple measure applicable only to the case of 2 × 2 contingency tables is the phi coefficient (φ) defined by = ± where χ 2 is computed as in Pearson's chi-squared test and N is the grand total of observations. φ varies from 0 (corresponding to no association between the variables) to 1 or −1 (complete association or complete inverse association) provided it is based on frequency ...
