Who is associated with using known probabilities of the past to predict the future?

• A. Karl Pearson
• B. Thomas Bayes
• C. Ronald Fisher
• D. Edwards Deming

Answer: (B)

Bayesian reasoning uses prior information from the past and updates it with new data to form updated beliefs about future outcomes. This is formalized by Bayes' theorem, which combines a prior probability (your initial view based on past information) with the likelihood of observed evidence to produce a posterior probability (your updated view about what will happen next). That’s why this name is associated with using known probabilities of the past to predict the future. The other figures are important in statistics for different reasons: Pearson and Fisher helped develop frequentist methods focused on long-run frequencies, while Deming emphasized quality management and process improvement rather than Bayesian updating.
