Q. Which of the following true regarding the following two curves (Blue and red) overall?: (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
Answer is B. (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)
