Data Mining question bank on BASMAGLY

A free multiple-choice question bank for the Data Mining course (CSC213), covering lectures 1 to 7. It has three sources you can study or test separately or together:

• Midterm - 27 questions from the Fall 2025-2026 midterm (Model A), with the answer sheet.
• Bank - 199 questions: a Data Mining question-bank PDF plus the 150 true/false questions from the lecture slides - KDD, data types, preprocessing, statistics and classification.
• Quizzes - 43 questions from DULMS and Moodle quiz reviews: preprocessing, cleaning, statistics, z-score, decision trees, Gini, splitting, clustering, scaling, induction and deduction, descriptive and predictive tasks.
• 438 questions in total. Every question has a short explanation in simple Egyptian Arabic and a tip to remember it.

Where a printed key looks questionable, the key is kept as printed and the explanation says so, so you can check it with your doctor.
