You are going to run a correlated groups design test on data. All assumption for a parametric test are met. There are two groups of data you are testing. For example: Group 1 Group 2 64.2 67.8 45.3 91.5 56.3 63.5 65.5 85.2 What type of statistical test would be run in this case? (ie independent T test, etc)

Summary statistics are given for independent simple random samples from two populations. Use the nonpooled t-test to conduct a two-tailed hypothesis test using a significance level of α = 0.01. x̄1 = 75, s1 = 4.5, n1 = 11, x̄2 = 65.5, s2 = 5.1, n2 = 9 Test statistic: t = 4.368 Critical values: ±2.916 Reject H0 Test statistic: t = 2.368 Critical values: ±2.878 Reject H0 Test statistic: t = 2.646 Critical values: ±2.916 Do not reject H0 Test statistic: t = 2.646 Critical values: ±2.878 Do not reject H0

The Mann-Whitney test is to independent samples t-test as Wilcoxon's matched-pairs signed-ranks test is to related sample means t-test.
