The former methods include tabulation and graphical display, of great importance both in detailed analysis and also in presentation of conclusions. Probability enters statistical analysis in various ways. The most obvious is that one recognizes explicitly that conclusions drawn from limited data are ...

Despite the enormous amount of attention given to this topic, psychology’s understanding of ToSS remains deficient. The major problem stems from a widespread and uncritical acceptance of null hypothesis significance testing (NHST), which is an indefensible...
