A study based on a sample of 20 participants calculates a value of 1.92 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(18) = 1.92, p > .01
B) t(19) = 1.92, p < .05
C) t(19) = 1.92, p > .05
D) t(19) = 1.92, p < .01
T-test
A statistical test used to compare the means of two groups.
Null Hypothesis
A statement in statistics that proposes there is no significance difference or effect, generally serving as the default or starting assumption in hypothesis testing.
Alpha
The threshold for significance in statistical testing, typically set at 0.05, below which the null hypothesis is rejected.
- Decide on the rejection or acceptance of the null hypothesis through analysis of p-values and threshold significance levels (alpha).
- Understand the suitable technique for conveying the outcomes of a statistical evaluation.
