Verified step by step guidance1
Step 1: Understand the concept of causal inference in psychology, which involves determining whether one variable directly influences or causes a change in another variable.
Step 2: Recognize that causal inference goes beyond simply observing a correlation or relationship between two variables; it requires evidence that changes in one variable produce changes in another.
Step 3: Differentiate causal inference from other concepts such as correlation (which only indicates a relationship without causation), assumptions about variable independence, and predictions based on past data.
Step 4: Recall that in the scientific method, establishing causality typically involves controlled experiments where variables are manipulated to observe effects, helping to support causal conclusions.
Step 5: Conclude that the best description of causal inference is a conclusion that one variable directly affects another variable, reflecting a cause-and-effect relationship.
