Question
Match the terms of List - I with that of List - II and select the correct option using the codes given below : Codes :List – I List – II (a) Standard score (i) 16.66 Z + 50 (b) Hull scale (ii) $\frac{X-m}{SD}$ (c) Sigma scale (iii) 14.28 Z + 50 (d) t scale (iv) 15.5 Z + 50 (v) 10 Z + 50
The correct answer is
(ii), (iii), (i), (iv)
Psychometric Scale Matching
Match the given psychological scales from List I to their corresponding transformation formulas in List II.
List I and List II Correlations:
- (a) Standard score corresponds to (ii) $\frac{X-m}{SD}$. This represents the Z-score, a standardized value indicating deviation from the mean ($m$) using the standard deviation ($SD$).
- (b) Hull scale corresponds to (iii) $14.28 Z + 50$. This transformation maps a Z-score to a scale with a mean of 50 and a standard deviation of approximately 14.28.
- (c) Sigma scale corresponds to (i) $16.66 Z + 50$. This transformation maps a Z-score to a scale with a mean of 50 and a standard deviation of approximately 16.66.
- (d) t scale corresponds to (iv) $15.5 Z + 50$. This represents a scaled score transformation with a mean of 50 and a standard deviation of 15.5, based on the provided options.
The correct option combines these specific pairings.
