Which of the following is true regarding the following two curves (Blue and red) overall?
Mean = Median = Mode
Mean = Median, not equal to Mode
Mean = Mode, not equal to Median
Mean, Median and Mode are not equal
The Red curve signifies the Normal distribution curve because it is bilaterally symmetrical, bell shaped. Hence, the Median=Mean=Mode. The blue curve can only be the curve of Mode as Mean and Median cannot have two peaks. Therefore, it is a BIMODAL distribution. Thus, Mean=Median, not equal to Mode Diseases showing bimodal distribution are Breast cancer & Hodgekin lymphoma.
