All Free Statistics MCQs with Answers

• A. ∑pn/∑po x100
• B. pn/po x100
• C. pn/pn-1 x100
• D. Both (a) and (b) but not (c)

Explanation: A chain index compares each period with the immediately preceding period, so its link relative is Pn/Pn−1 × 100. Comparing every period directly with one fixed base gives a fixed-base index instead.

• A. Fixed
• B. Constant
• C. Change
• D. None of these

Explanation: In the chain-base method, the reference period changes from one link to the next, so each period is compared with the preceding period. This differs from the fixed-base method, where the base remains constant.

• A. Science
• B. Education
• C. Intelligence
• D. Business

Explanation: Index numbers summarize changes in prices, quantities, or values and are widely used in economics and business for comparison and decision-making. Science and education may use statistics, but business is the standard paired field here.

• A. variable
• B. Region of goods
• C. Device
• D. CostPolitical Science Mcqs

Explanation: An index number is a statistical device for measuring changes in a variable or a group of related variables over time. The wording is slightly corrupted, but “Device” gives the intended definition.

• A. Simple 1. No.
• B. Aggregative 1. No.
• C. Appropriate
• D. Quantity Index Number

Explanation: A quantity index number measures changes in the physical quantities of goods, such as units produced or sold. A price index instead measures changes in prices, so the quantity-based option is appropriate.

• A. Fixed Method
• B. Chain Method
• C. Aggregation Method
• D. Volume

Explanation: In the chain-base method, each period is compared with the immediately preceding period, so the preceding year’s price is used. A fixed-base method compares every period with one constant base year.

• A. Four
• B. Three
• C. Five
• D. Two

Explanation: Weighted index numbers are commonly divided into two main categories: weighted aggregative indices and weighted average-of-price-relatives indices. Therefore, the number of categories is two.

• A. Price relative
• B. Link relative
• C. Retail prices
• D. None of these

Explanation: The price relative is the current-year price divided by the base-year price, multiplied by 100. A link relative instead compares the current period with the immediately preceding period.

• A. Sensitive Price Index number
• B. Consumer Index Number
• C. Simple Aggregation 1. Number
• D. Chain Indices

Explanation: An index covering several items is an aggregate or composite index; the listed option refers to a simple aggregative index number. A consumer price index is a particular type of composite index, not the general definition asked here.

• A. Commodities
• B. Time Series
• C. Whole sale
• D. Realtives

Explanation: Seasonal and cyclical movements are components of a time series, and index-number techniques can help measure such variations. Commodities and wholesale prices are subjects that may be studied, not the statistical series itself.
