Q:

# What does frequency mean in mathematics?

A:

In math, the frequency is the number of times a specific value appears in a data set or list. To find the frequency of these values, one constructs a frequency table and inputs all the different values from the set.

For example, for the data set 2, 5, 4, 7, 2, 8, 2, 6, 7, 2, one makes a table with columns, where the first column contains these given values in ascending order as 2, 4, 5, 6, 7 and 8. The table also has a tally column and frequency column. One records the tally in the second column and the frequency in the third column.

After constructing a table for the given values of the data set, one sees that for the value 2, the frequency is 4, for 7 the frequency is 2, and the other values 4, 5, 6, 8 have a frequency of 1 each.
