Vanessa Lauermann,Débora N. F. Barbosarvations in two different groups. We define similarity using some appropriate distance measures. Then, we discuss two main classes of clustering methods, namely, .-means clustering and hierarchical clustering.

Exploring Relationships,We start by discussing situations where we are interested in the relationship between two numerical variables. Next, we talk about techniques for investigating the relationship between two categorical variables. Finally, we discuss situations where one variable is numerical and the other one is categorical.

Online Examination – A Case Study only one categorical factor defining the groups. We refer to the ANOVA method for such problems as one-way ANOVA. Next, we briefly discuss two-way ANOVA methods, where the groups are defined based on two factors (i.e., categorical variables).

Michal Ďuračík,Emil Kršák,Patrik Hrkúton by focusing on situations where there is only one explanatory variable. We refer to these models as simple linear regression models. We then extend simple linear regression models to multiple linear regression models, where there are two or more explanatory variables.

Lorna Uden,Dario Liberona,Jozef Ristvejing the possible values of unknown parameters (e.g., population proportion) before observing data. Posterior probability distributions reflect our updated knowledge about unknown parameters after observing data. We show how posterior probability distributions are used to estimate parameters and perform hypothesis testing.

Sabine Siemsen,William Yu Chung Wangecifically, we divide variables into categorical and numerical. Distinguishing these two types of variables is important because the summary statistics and data visualization techniques appropriate for a variable usually depend on the type of that variable. This chapter also provides some discussion on data preprocessing.

Learning Technology for Education Challengesa random variable depends on its type. We divide random variables into discrete and continuous based on the type values they take and whether these values are countable. We then talk about some commonly used discrete and continuous probability distributions.
