Effect size values are a statistical concept that provide a measure of the magnitude of the difference, association, or relationship in the population. They can help a researcher or reader determine:

1. Statistical significance: Effect size values can help determine if the observed effect in the sample is likely to be found in the population. This is because statistical significance is influenced by the effect size. A larger effect size can lead to a higher statistical significance.

2. If an effect is meaningful: Effect size values can help interpret the practical significance or importance of the results. A statistically significant result does not necessarily mean it is practically significant. For example, a drug may statistically significantly increase the survival time of patients, but if the increase is only a few minutes, it may not be practically significant.

3. The sample size: Effect size values can be used in power analysis to determine the required sample size for a study. A larger effect size requires a smaller sample size to detect the effect.

4. If you should reject or fail to reject the null hypothesis: Effect size values can help in the decision to reject or fail to reject the null hypothesis. A larger effect size provides stronger evidence against the null hypothesis. However, the decision also depends on the significance level and the power of the test.
