Further Statistics 2: regression, densities and tests flashcards

15 cards drawn from 11 lessons: 10 standard results, 2 definitions, 1 recall prompt, 1 check-yourself question and 1 spot-the-error card. Least squares, continuous distributions, and confidence intervals and tests for means and variances. Rate each answer to set a shorter or longer interval before the card is due again.

How the five kinds differ

Standard results ask for a formula or value that may need to be recalled. Definitions ask for a mathematical term to be stated precisely. Recall prompts ask for a rule, condition or method. Check yourself cards contain a short question and answer. Spot the error cards ask you to correct an inaccurate claim.
