Statistics: Concept Notes Before Practice

Statistics questions in SSC CGL reward clean setup more than long calculation. Before attempting the tests, revise the base formula, the fastest conversion, and the common option trap for this topic.

Rough-work frame: Formula -> values -> equation -> shortcut -> option check

What to Master

Build the equation or ratio first; calculate only after the structure is clear.
Memorise standard fractions, squares, cubes, and percentage conversions used in SSC arithmetic.
Use option checking when choices are close but avoid blind substitution before reading the condition.

Easy Examples

Percentage change: new value = old value x (100 +/- change)% / 100.
Average logic: total = average x number of items.
Profit-loss: always identify cost price before applying gain or discount.

Exam Traps

Do not mix marked price, selling price, and cost price.
Successive percentage changes are not added directly.
In time-work questions, compare work done per unit time, not total time first.

World-Class Study Method for This Topic

1. Learn: write the rule, formula, pattern, or fact in your own words.

2. Diagnose: solve five untimed examples and name the question type.

3. Speed: solve the next ten questions with a strict timer and skip rule.

4. Repair: revise only mistakes and write one prevention rule for each.

Mistake Log

Wrong concept: what rule was missing?

Wrong reading: which word changed the meaning?

Wrong speed: should this question be skipped first?
