These statistics have been found from a reliable source dealing with alcoholism as a disease. There really is no way of knowing if you will become an alcoholic just because one or both of your parents drink alcohol. guess the bottom line is that if you choose to drink alcohol, then you will get drunk and itâs possible that you will have a battle with it like your mother or father did. Just donât do it at all.
Confidence intervals are also very useful for comparing means or proportions and can be used to assess whether there is a statistically meaningful difference. This is based on whether the confidence interval includes the null value (e.g., 0 for the difference in means, mean difference and risk difference or 1 for the relative risk and odds ratio).
If you want to characterize the precision of the study, or if you want to characterize the certainty / uncertainty of the estimation of the mean in your study, you should use SEM or confidence interval (CI). I prefer 95%-CI because it is directly linked to p-values at 5% level.
