Calculate the mode of the following data : 4, 6, 5, 7, 9, 8, 10, 4, 7, 6, 5, 8, 7, 7, 9.
Mode is the value that repeats a maximum number of times in a dataset. To find the Mode here, we need to see the digit which has been repeated a maximum number of times. Like the digits, 4,5,6,8,9 have come 2 times ( it can be found very easily by simply counting the number of occurrences ), similarly number 10 has come only once but the digit 7 has come four times.
The mode for this data is 7 because 7 occurs most frequently, i.e., 4 times in the data.
