DISCREET AND CONTINUOUS DATA

CONTINUOUS AND CATEGORICAL DATA

Data in psychology can be categorised as continuous or categorical (also called discrete). Continuous data refers to numerical values that can take any value within a range, such as height, weight, or reaction time. It is measured on a scale and often analysed using means or standard deviations.

Categorical data, on the other hand, involves distinct categories or groups. Examples include gender, ethnicity, or types of therapy. This data is non-numerical and is often summarised using frequencies or percentages.

Understanding the distinction is key to choosing the right statistical tests and interpreting psychological research effectively.
