Important Concepts
Bimodal – If in the given data set, we have the two modes, then we can call it the Bimodal Mode.
Eg = { 2 , 2 , 2 , 3 , 4, 4 , 4 , 5 , 5 }
Here, in the above set, we have 2 and 4 coming three times with the largest frequency in the given order. Hence this is the answer.
Trimodal – If in the given data set, we have the three modes, then we can call it the Trimodal Mode.
Eg = { 2 , 2 , 2 , 3, 3 , 3 , 4 , 4 , 5 , 5 , 5 , 6, 6}
Here, in the above set, we have 2, 3, and 5 coming three times with the largest frequency in the given order. Hence this is the answer.
