Comparisons Using Estimates and Intervals
Comparisons Using Estimates and Intervals
This chapter pulls together material from earlier chapters to give an introductory user’s guide to error bars and intervals. There is no ‘best’ interval that suits all needs. Several different types of intervals are compared: standard deviations; standard errors of means; standard errors of differences; confidence intervals; least significant differences. The pros and cons of these main types of interval are reviewed. The results are presented using R graphics.
Keywords: error bars, intervals, standard deviation, confidence interval, least significant difference, R graphics
