Q. Which of the following true regarding the following two curves (Blue and red) overall? 
Select and explain. 
A. Mean = Median = Mode, B. Mean = Median, not equal to Mode, C. Mean = Mode, not equal to Median, D. Mean, Median and Mode are not equal
B: Mean = Median, not equal to Mode
Answer: B: Mean = Median, not equal to Mode 
Explanation: (b) Mean = Median, not equal to ModeIn the given question,* Red curve is Bilaterally symmetrical, bell shaped curve, hence it's a Normal distribution- In Normal distribution, Mean = Median = Mode (Green vertical line)* Blue curve has two modes (both symmetrical too), hence it's a Bimodal distribution- Since Bimodal curve is symmetrical, its Mean and Mode would lie at intersection 'X', so Mean = Median (Black arrow)
