What does it mean to say that the results of an experiment are "statistically significant"
A) The results had practical significance.
B) Differences in measurements of the dependent variable resulted from chance variations.
C) Different results for the experimental and control groups were not due to chance.
D) The results were important enough to publish.
Statistically Significant
A determination that results in observed data are not likely to be due to chance alone, according to predetermined thresholds in statistical analysis.
Experimental
Relating to a scientific procedure undertaken to make a discovery, test a hypothesis, or demonstrate a known fact.
Control Group
In experimental research, a group of subjects that does not receive the treatment being tested and is used as a benchmark to measure how the other tested groups do.

Final Answer :
C
Explanation :
Statistically significant results mean that the differences observed between groups (experimental and control) or in measurements of the dependent variable were not due to chance. This is typically determined through statistical analysis and a pre-determined level of significance, such as p < 0.05. Practical significance (A) refers to the real-world importance of the results, which may or may not align with statistical significance. Choice B is the opposite of statistically significant, and choice D refers to the importance of publishing results, which is not directly related to statistical significance.
