1. In statistics the term frequency is normally thrown around, especially relating to tables and charts. Explain the term frequency in statistics as well as the concept of cumulative frequency. 2. As mentioned above, tables and charts are used to illustrate data in statistics. Some of the common tables and charts used are tally charts, cumulative frequency table, bar/ column chart, histogram and pie chart. 3.
