Yule's coefficient of association Q is calculated using frequencies from a:
A. Time series data
B. Scatter plot
C. 2×2 contingency table for two binary attributes
D. Frequency distribution table
Answer: Option C
Solution (By JKSSB Mock Tests)
Yule's Q = [(AB)(αβ) - (Aβ)(αB)] / [(AB)(αβ) + (Aβ)(αB)], requiring the four cell frequencies of a 2×2 table cross-classifying two dichotomous attributes.
