If you have two main effects, and one main effect is significant, this means that d. The other main effect and the interaction effect may or may not be significant
What exactly is a significant effect in research?
A statistically significant result indicates that it is unlikely to be explained solely by chance or random factors. In other words, if there is no true effect in a research study, a statistically significant result has a very low chance of occurring.
The significance level is the threshold at which one can accept whether an event is statistically significant. Researchers use the p-value to determine statistical significance: if the p-value is less than the significance level, the result is statistically significant.
If you have two main effects and one of them is significant, the other one and the interaction effect may or may not be significant.
In conclusion, based on the information illustrated, the correct option is D.
