WebApr 2, 2024 · The test statistic is: (11.7.1) χ 2 = ( n − 1) s 2 σ 2. where: n is the the total number of data. s 2 is the sample variance. σ 2 is the population variance. You may think … WebThe Method column denotes which test is being used for that row, and the Variances column indicates what assumption about variances is being made. The pooled test assumes that the two populations have equal …

WebMar 29, 2024 · In practice, pooled variance is used most often in a two sample t-test, which is used to determine whether or not two population means are equal. The pooled variance between two samples is typically denoted as s p 2 and is calculated as: s p 2 = ( (n 1-1)s 1 2 + (n 2-1)s 2 2 ) / (n 1 +n 2-2) pester plumbing inc
