What the exams ask here
- mean / median / mode of a small list; true-false statements about them (JIPMAT 2023 Q32)
- median of a frequency table; mode of grouped counts
- max + min = 15 and median - mean = 2 -> median (Indore 2025); empirical mode = 3 median - 2 mean
- distinct integers with a given median and maximum: extreme sums / means
- mean of combined or overlapping groups (JIPMAT 2023 Q8: first 13 and last 13 of 25)
- weighted (stratified) means and expected values
- Indore 2024 SA set: companies with counts and median ages, strictly ordered - overall median, highest possible age, lowest possible sum of ages
