First identify the variable type; then count how often a value occurs. Relative frequency is absolute frequency divided by the total number of observations.
In this lesson: Distinguish qualitative, quantitative discrete and continuous data and calculate absolute and relative frequencies.
How to proceed: Qualitative data describe categories; quantitative discrete data come from counting; quantitative continuous data come from measurement. For relative frequency divide the count by the total.
You can already assume: Counting; percentages recommended.

Data: Variable: height in metres. Data: 1.62, 1.70, 1.68, 1.70, 1.75, 1.62. Value to track: 1.70.
ConceptStep separates what is required from what is recommended or useful as reinforcement. Only required prerequisites block your progress.
Relationships: solid line = required · dashed line = recommended · dotted line = reinforcement.
