Mean, median and mode differ as follows:

Point	Mean	Median	Mode
Basis	arithmetic average	middle value	most frequent value
Uses	further calculations	skewed/outlier data	typical/most common
Affected by extremes	yes	no	usually no

(Any three points can be written.)

Types of correlation include:

Positive, negative and zero correlation (by direction).
Simple, multiple and partial correlation (by number of variables).
Linear and non-linear correlation (by form).

(Any three types can be written.)

Index numbers are statistical measures that show relative change in a variable (or group of variables) over time, usually with the base period taken as 100. They are widely used to measure inflation, cost of living and trend changes in business and economics.

Important formulas for price index numbers:

Index	Formula
Simple aggregative	(Σp1 / Σp0) × 100
Simple average of relatives	[Σ(p1/p0 × 100)] / n
Laspeyres	[Σ(p1q0) / Σ(p0q0)] × 100
Paasche	[Σ(p1q1) / Σ(p0q1)] × 100
Fisher	√(PL × PP)

Thus, formula selection depends on whether weights are used and whether base or current quantities are considered.
