Question

what does it mean for the findings of a statistical analysis of data to be statistically significant? choose the correct answer below. a. the outcome could easily occur by chance. b. the results are very important to the health and well-being of a certain population. c. the likelihood of getting these results by chance is very small. d. the results do not make enough difference to be of use.

Explanation:

Statistical significance means that the likelihood of obtaining the results by random chance (sampling error) is very low. Option A is incorrect as significant results are not likely by chance. Option B is about practical importance (clinical significance), not statistical. Option D is about practical utility, not statistical significance. Option C correctly defines statistical significance as a small chance of results being due to chance.

Answer:

C. The likelihood of getting these results by chance is very small.
