An independent study with a sample size of 6 found a mean difference of 4 points between two groups and a pooled variance of 12. To calculate the t-statistic for this study, the formula is t = (M1 - M2) - (u1 - u2)]/sqrt(Vp/n1 + Vp/n2) where M1 and M2 are the sample means, u1 and u2 are the population means, Vp is the pooled variance, and n1 and n2 are the sample sizes.

1. an independent measures study with n=6, produces a sample mean difference of 4 points and a
pooled variance of 12. what is the t statistic
Solution
You're given the pooled variance Vp=12, which means you're assuming that the population
variances V1,V2 for the two statistics are equal. By making that assumption,
t = [(M1 - M2) - (u1 - u2)]/sqrt(Vp/n1 + Vp/n2)
