A researcher computed the F ratio for a four-group experiment. The computed F is 4.86. The
degrees of freedom are 3 for the numerator and 16 for the denominator.
1. Is the computed value of F significant at p < .05? Explain.
2. Is it significant at p < .01? Explain
ANSWER:
1. The computed F = 4.86, df = 3 in the numerator, and df = 16 in the denominator.
Hence, the p-value is computed to be 0.0137.
Since the computed p-value = 0.0137 < level of significant α = 0.05. We therefore reject the null
hypothesis H
0
and thus conclude that the computed value of F is significant at p < 0.05.
2. The computed F = 4.86, df = 3 in the numerator, and df = 16 in the denominator.
Hence, the p-value is computed to be 0.0137.
Since the computed p-value = 0.0137 > level of significant α = 0.01. We therefore do not reject
the null hypothesis H
0
and thus conclude that the computed value of F is not significant at p <
0.01.
