Year 2 – Period 5 – Statistics IIStatistics IIOrganisational – Topics covered in Statistics 21. Analysis of Variance – One way ANOVAo only 1 independent variableo applied when we have compared a quantitative dependent variable in k different groups aspart of an experimental design.2. Two-way ANOVAo two factors (or experimental factors), giving two possibilities: we have either a balanceddesign, or an unbalanced design.o The special case of unbalanced designs can give rise to the problem of confounding betweenvariables, which can potentially be resolved statistically using an ANCOVA model3. ANCOVAo Knowledge of elementary regression analysis,4. Multiple Regression Analysiso data collected by observational studies are often analysed using a regression model.o Analysis models involve one dependent variable that we wish to predict using multipleindependent variables (also called ‘predictors’)  ‘multiple regression analyses’5. Within Subjects ANOVAo the simplest variant of this model (1 independent WS variable)6. Within Subjects ANOVA (2 independent variables)o examine two variants: one in which both independent variables are WS (which is called a fullWS design), and one that involves one WS independent variable and one BS independentvariable split-plot designs.1Year 2 – Period 5 – Statistics IIStatistics I – RepetitionProbability distribution of X: describes probability of occurrence for each value of X, if randomexperiment were repea … Purchase document to see full attachment
