Contingency analysis

Example | Business

Is firm performance related to a firm’s customer centricity?

Example | Medicine

Is there an association between smoking and dying of lung cancer?

Example | Psychology

Are self-regulation in childhood and subsequent levels of achievement related?

Example | Biology

Are weather conditions (rainy vs. sunny) associated with the occurrence of ticks?

Contingency analysis examines relations among two or more nominally scaled variables. For example, we can investigate the relation between smoking (smoker versus nonsmoker) and lung cancer (yes, no). We do so with the help of a cross-table (contingency table) that maps the occurrence of combinations of levels of the nominal variables.
