Question

Which of the following results from a hypothesis test involving the computation of a t-statistic is structured correctly based on standards for presenting hypothesis tests in scientific reports?

a.
t(19) = 2.30, r2 = 0.42, p < .05
b.
t(19) = 2.30, p < .05, r2 = 0.42
c.
r2 = 0.42, t(19) = 2.30 , p < .05
d.
t = 2.30, df = 19, p < .05, r2 = 0.42

Answer 1

Answer:

The correct answer is: b. t(19) = 2.30, p < .05, r2 = 0.42.

This presentation follows the standard format for reporting the results of a hypothesis test involving the computation of a t-statistic. The t-value and degrees of freedom are reported in parentheses, followed by the level of statistical significance (p-value). The effect size measure r^2 is then reported after the significance level.

Option a is incorrect because the effect size measure r^2 is typically presented after the significance level. Option c is also incorrect because it presents the effect size measure before the t-value and the significance level. Option d is incorrect because it does not include the degrees of freedom in parentheses next to the t-value.
