Question

Match List - I with List - II. 

Choose the correct answer from the options given below : 
 

• A. A-I, B-II, C-IV, D-III
• B. A-IV, B-I, C-II, D-III
• C. A-IV, B-II, C-I, D-III
• D. A-I, B-II, C-III, D-IV

Hint:

A classic analogy: Think of a dartboard.
Accuracy is hitting the bullseye.
Precision is throwing 5 darts and hitting the exact same spot 5 times (even if it's far away from the bullseye).

Answer 1

The Correct Option is C

Step 1: Concept:
The question asks to match fundamental data collection and statistical terminology with their formal definitions.

Step 2: Step-by-step Explanation:

• A. Precision: Precision defines the degree of reproducibility or repeatability. It is defined as the closeness of repeated measurements of the same quantity to each other, regardless of whether those measurements are close to the actual true value.
Thus, A matches with IV.

• B. Accuracy: Accuracy defines correctness. It is universally defined as the closeness of a measured or computed value to its actual true (or accepted) value.
Thus, B matches with II.

• C. Reliability: In research methodology, reliability refers to the overall consistency of a measure. It heavily depends on the preciseness of the procedure used for data collection; a highly precise and standardized procedure yields highly reliable (repeatable) data.
Thus, C matches with I.

• D. Sampling: Sampling is the fundamental statistical practice of selecting a few representative units from all the observational units (the entire population) to estimate population parameters without taking a complete census.
Thus, D matches with III.

• The consolidated matching sequence is: A-IV, B-II, C-I, D-III.

Step 3: Final Answer:
The correct matching sequence is given in Option (C).
