Question
Which statement is the best as a general rule for interpreting the level of significance of a statistical test?*a. If p < .10, it is statistically significantb. If p > .10, it is marginally significantc. If p < .01, it is non-significantd. If p < .05, it is significant
Solution
The best general rule for interpreting the level of significance of a statistical test is "d. If p < .05, it is significant". This is because the p-value is a measure of the probability that an observed difference could have occurred just by random chance. The lower the p-value, the greater the statistical significance because it tells the investigator that the hypothesis under consideration may be true. The widely accepted standard for a statistically significant p-value is less than 0.05.
