A common example of this is the normality assessment of a data distribution. A vast quantity of papers can be found where the authors conclude the normality of data distributions based on very small samples. 6, even with 25-sized samples one would often be wrong when admitting that a data distribution is normal because a statistical test didn’t reject that possibility at a 95% confidence level. More: one would often be accepting the normality of data generated with asymmetrical and even bimodal distributions!

The confidence level can then be interpreted as a risk (the risk incurred by “a reasonable doubt” in the jury verdict analogy). The higher the confidence level, the lower the risk we run in basing our conclusions on atypical samples. 025. 7 that the intervals would grow wider so that now only 1 out of 100 intervals does not contain p. The main ideas of this discussion around the interval estimation of a proportion can be carried over to other statistical analysis situations as well. As a rule, one has to fix a confidence level for the conclusions of the study.
