The program is mainly used in:
Statistics education
Statistical Inference Laboratory
Sila teaches students the concepts of statistical inference which manyof them find hard to understand. Students often don"t see the stochasticcharacter of a statistic and they are e.g. mixing up param meters andtheir estimates.Sila has certain advantages over textbooks and statistical packages:* Sila works on the basis of a concept map which shows the relationships between a population, a sample a nd a statistic,* this concept map is dynamic: it is continuously updated,* Sila gives all screen elements (windows, texts, graphs, edit fields) their natural position and contents (e.g. greek symbols , subscripts and superscripts),* Sila is interactive: the user can modify characteristics of an inferential problem and study its consequences on the basis of the supplied feedback,* the user can e nter samples or let the computer generate samples,* the variability of a sample, a statistic and confidence limits is (graphically) shown,* concepts in testing theory are graphically shown: null hyp othesis, alternative hypothesis, p-value, critical value, a statistic"s distribution under H0 and under alternative parameter values, power and the power function,* a teacher can compose assignment problems,* a student can study a self-chosen problem or an assigned problem in which case additional feedback is given.
