Question

A study based on a sample of 14 participants calculates a value of 2.58 for the t-test for a single mean. For alpha (α) = .05 (two-tailed), which of the following is the correct way to present this analysis?
A) t(13) = 2.58, p < .05
B) t(13) = 2.58, p > .01
C) t(14) = 2.58, p < .05
D) t(14) = 2.58, p < .01

The correct way to present the t-test analysis is with degrees of freedom (df), which is calculated as the sample size minus one (n-1). For a sample of 14, df = 14 - 1 = 13. The p-value indicates the probability of observing the test results under the null hypothesis. A p-value less than .05 indicates statistical significance at the alpha level of .05, hence "p < .05" is correct.
