Question

A study based on a sample of 22 participants calculates a value of 1.86 for the t-statistic. For alpha (α) = .05 (two-tailed), which of the following is the correct way to present this analysis? A) t(20) = 1.86, p > .01 B) t(21) = 1.86, p > .05 C) t(21) = 1.86, p < .01 D) t(22) = 1.86, p < .05

The correct way to present the analysis is with the degrees of freedom (df), which is calculated as the sample size minus one (n-1). For a sample of 22, df = 22 - 1 = 21. The p-value is not specified, but "p > .05" indicates that the result is not statistically significant at the .05 level, which is consistent with a t-value of 1.86 without knowing the exact critical value for this df.
