Fisher's ideal index for price is given by: MCQ with Answer and Explanation

Fisher's ideal index for price is given by:
A. (Σp₁q₀/Σp₀q₀ + Σp₁q₁/Σp₀q₁)/2
B. Σp₁q₀ / Σp₀q₀
C. Σp₁q₁ / Σp₀q₁
D. √[(Σp₁q₀/Σp₀q₀) × (Σp₁q₁/Σp₀q₁)]
Answer: Option D
Solution (By JKSSB Mock Tests)
Fisher's ideal price index is the geometric mean of the Laspeyres price index (Σp₁q₀/Σp₀q₀) and the Paasche price index (Σp₁q₁/Σp₀q₁), ensuring it satisfies key consistency tests.

Question #2
In a frequency distribution, if the mean is 50, median is 48, and mode is 45, the distribution is likely:
A. Symmetrical
B. Negatively skewed
C. Bimodal
D. Positively skewed

Correct Answer: Option D


Explanation:
In a positively skewed distribution, mean > median > mode due to the pull of extreme high values; here, 50 > 48 > 45 aligns with this pattern, indicating right-skewness.

Question #3
In a dataset with an even number of observations, the median is calculated as:
A. The most frequent observation
B. The average of the two middle observations
C. The weighted average of all observations
D. The middle observation

Correct Answer: Option B


Explanation:
For an even number of ordered observations, the median is the arithmetic mean of the two central values, ensuring it represents the center of the distribution.
