How is 'functional relationship' defined? | some causal relationship between inputs and outcomes |
What are the two major types of functional relationships? | 1. a LINEAR relationships exists when IV changes by a constant amount; 2. a NON-LINEAR relationship exists when constant changes in the IV produce non-equal changes in the DV |
Why are graphs used? | to understand functional relationships among variables |
When is a line graph used? | when the IV represents a continuum of some kind |
When is a bar graph used? | when the values of the IV are not in any hierarchical order |
