PYQ Practice Set 1
Seventeen statistics questions exactly as SSC set them, almost all from the Tier 2 maths papers: 4 from CGL 2022, 1 from CGL 2023, 2 from CGL 2024 and 3 from CGL 2025, 4 from CHSL Tier 2, 1 from Selection Post 2025, and 2 from CGL Tier 1 papers that asked for a mean or mode from a table or a graph. The paper is named after each question. Medians lead this set, from a plain list to a grouped table that needs the formula, so arrange every list before you look for the middle value, and remember that for grouped data the median sits at the -th value. Give it about 17 minutes, the Tier 2 pace of a minute a question; 14 or more right is a good sign that these questions are under control at exam speed.
