Using the confidence interval confidently. [PDF]

open access: yesJ Thorac Dis, 2017
Biomedical research is seldom done with entire populations but rather with samples drawn from a population. Although we work with samples, our goal is to describe and draw inferences regarding the underlying population. It is possible to use a sample statistic and estimates of error in the sample to get a fair idea of the population parameter, not as a

The fallacy of placing confidence in confidence intervals [PDF]

open access: yesPsychonomic Bulletin & Review, 2015
Interval estimates - estimates of parameters that include an allowance for sampling uncertainty - have long been touted as a key component of statistical analyses. There are several kinds of interval estimates, but the most popular are confidence intervals (CIs): intervals that contain the true parameter value in some known proportion of repeated ...

Sample size estimation for correlations with pre-specified confidence interval [PDF]

open access: yesTutorials in Quantitative Methods for Psychology, 2014
A common measure of association between two variables x and y is the bivariate Pearson correlation coefficient rho(x,y) that characterizes the strength and direction of any linear relationship between x and y.
