Which has more interpretive value, a confidence interval, a p value, or a statement about statistical significance?
Explain. A confidence interval gives information about the point estimate (which can be inferred from the interval) and its precision. A P- value, which is a measure of consistency between the data and the null hypothesis, does not give information about the ‘best guess’ (point estimate). Statistical significance testing is a dichotomous description of the P-value and is therefore even less informative than the P-value.
