represents a perfect positive correlation. The correlation analysis is reported in section 4.8. 3.8.3 Factor Analysis Factor analysis is a statistical method used to describe variability among observed variables in terms of fewer unobserved variables called factors (Martin et al., 1996:369). The...

This study is considered a correlational study since it describes the relationship between the dependent variable (e-payment utilization) and the independent variables (trust in the...
approach to research that involves measuring two or more variables to describe the relationship between the variables. The variables are measure and record to obtain a set of scores, usually two scores, for each individual; the measurements are then review to identify any patterns of relationship...

For example, Stem, McCants, and Pettine (1982) found that the positivity of the relation between changing life events and severity of illness was considerably stronger for uncontrollable events (e.g., death of a spouse...
