We have a dataset that is:
50 60 80
90 50 70
40 50 80
We have to identify the mode of this dataset.
The mode is the value in the dataset that has the highest frequency. We can have more than one mode if there is more than one value with the maximum frequency.
To find the mode it is usually helpful to count the frequency for each element.
We can do it as:
50: III
60: I
80: II
90: I
70: I
40: I
As "50" has the highest frequency, with a value of 3, it is the mode of the dataset
Answer: the mode is 50.
