What is the key concept in statistics that involves drawing a conclusion from available evidence?

• A. Inference
• B. Estimation
• C. Hypothesis
• D. Prediction

Answer: (A)

Interpreting sample data to reach conclusions about a larger population is inference. It’s the process of using available evidence to say what’s likely true about the population behind the data. Inference is the broad activity, and estimation, hypothesis testing, and prediction are specific ways we apply it: estimation quantifies an unknown population parameter, hypothesis testing evaluates a claim about the population, and prediction forecasts future observations. Because the prompt describes drawing conclusions from evidence, inference is the best fit.
