Question
Differentiate between Fixed base and Chain base methods. (Any 3 points)

Answer

Differentiation: Fixed Base vs. Chain Base Method
FeatureFixed Base MethodChain Base Method
Base PeriodRemains constant (fixed) for all years.Changes every year; the preceding year is the base.
ComparisonEasy to compare current data with a specific past periodIdeal for comparing data with the immediate past.
FlexibilityRigid; difficult to include new items or delete old ones.Flexible; new items can be added or deleted easily.
