The mode of the following distribution is `{:("Class interval",f),(" "1-5,4),(" "6-10,7),(" "11-15,10),(" "16-20,8),(" "21-25,6):}`A. 14.5B. 16.5C. 10.5D. 13.5

Answer» Correct Answer - D
(i) Mode `= L + (Delta_(1) C)/(Delta_(1) + Delta_(2))`
(ii) Identify `f_(1), f_(2) "and" L`
(iii) Mode `= L + (Delta_(1))/(Delta_(1) + Delta_(2)) xx C ("where" D_(1) = f - f_(1) "and" D_(2) = f - f_(2))`
