Mode

Mode, M is the value that has the largest number of occurrence or frequency in a data set, for instance, given the following data:

 11 15 16 12 15 19 17 15

we can see that number 15 occurred the most (three times) than the rest. Thus the mode is 15.

 · When two values occur with the same largest frequency, now here each one is a mode and the data set is bimodal.

 · When more than two values occur with the same greatest frequency, now hear each is a mode and the data set is said to be multimodal.

 · When no value is repeated, we can say that there is no mode.

Example

Find the modes of the data sets given below.

a. 5.40 1.10 0.42 0.73 0.48 1.10

b. 27 27 27 55 55 55 88 88 99

c. 1 2 3 6 7 8 9 10

Solution is as follows

a.1.10

b. 27 and 55 ( two modes - bimodal)

c. no mode
