Question

Measures of variations or dispersion of data are: A. Interquartile Range B. Mode C. Standard Deviation D. Weighted Mean

• A. A and D only
• B. A and C only
• C. B and C only
• D. A and B only

Hint:

Dispersion measures like the interquartile range and standard deviation help understand the spread of data, whereas measures like the mode focus on central values.

Answer 1

The Correct Option is B

Step 1: Understanding Variation Measures

- The interquartile range (A) and standard deviation (C) quantify data dispersion or variation.
- The mode (B) represents central tendency, not dispersion.
- The weighted mean (D) also measures central tendency.
