This is an introductory text for the first course in Inferential Statistics for undergraduate students in Science & Engineering. The methods we present are fundamental to statistical analysis to other disciplines as well. STATISTICS FOR SCIENCE & ENGINEERING 3 discusses statistical inference on three or more means, namely analysis of variance (ANOVA). Both the one-way ANOVA and two-way ANOVA (with and without interaction) are included. This text also covers another area of inferential statistics which are Correlation and Regression Analysis.
