Marital status; Continuous Data Value. Independent and Dependent variable In conducting research, students may be interested in studying the relationships between variables or even predicting one variable from another variable. Chapter 1 Variables and Their Measurement. A Discrete variable can take either a finite or a countable number of values. Categorical data can be further classified as: nominal when the categories do not have an order, such as for a 'marital status' variable (furthermore, if there are only two categories then the terms binary and/or dichotomous are sometimes used); or Discrete variable - a variable whose values are countable, or can only assume certain values with no intermediate values . Continuous data. If a data set is continuous, then the associated random variable could take on any value within the range. Water temperatures of six swimming pools in Jeddah on a given day.
