            The table above is the list of Olympic medals won over the full career of the players. This list includes athletes
            who have won seven or more Olympic medals over their sporting career. Now if you are interested in finding only
            woman athletes which have won, then you have to make a subset databased by sorting the gender column.


            1.3. ONE-WAY FREQUENCY TABLE

            Frequency means the number of times an event or a value occurs. A frequency table is a table that lists items and
            shows the number of times the items occur.
            Frequency tables are usually produced on individual variables. For categorical data, the table records the number
            of observations (the frequency) for each unique value of the variable. The frequency table records the number of
            observations falling in each interval. We represent the frequency by the English alphabet ‘f’.

            For example, Viraj has to put the footballs in two boxes. He starts dropping one football after the other into two
            boxes named A and B. Viraj drops the balls randomly, and after dropping 10 balls, he takes some rest and then
            again repeats the task with the remaining 10 balls.
            The tables given below show the pattern of how Viraj drops the footballs in two boxes.

            Such a table is known as the frequency table. We create the table by arranging collected data values and their
            corresponding frequencies. The aim of constructing this table is to show the number of times a value occurs.
