A Primer on Confidence Intervals.
Pizzitola, Kelly M.
The recent American Psychological Association Task Force on Statistical Inference report suggested that confidence intervals should always be reported. Other researchers also agree that confidence intervals should be used as a supplement to statistical significance testing. The confidence interval is defined as a range of values constructed around a point estimate that makes it possible to state the probability that the interval contains the population parameter between its upper and lower confidence limits. This paper examines specific flaws in statistical significance testing, as reported by these researchers, and suggests the use of confidence intervals based on the recommendations of the Task Force. The construction of confidence intervals using range null hypothesis, as opposed to null hypothesis, is also discussed. (Contains 26 references.) (SLD)
