,Introduction
When conducting a statistical study, the researcher must gather data for the partic-
ular variable under study. For example, if a researcher wishes to study the number
of people who were bitten by poisonous snakes in a specific geographic area over the
past several years, he or she has to gather the data from various doctors, hospitals,
or health departments.

To describe situations, draw conclusions, or make inferences about events, the
researcher must organize the data in some meaningful way. The most convenient
method of organizing data is to construct a frequency distribution.

After organizing the data, the researcher must present them so they can be under-
stood by those who will benefit from reading the study. The most useful method
of presenting the data is by constructing statistical charts and graphs. There are
many different types of charts and graphs, and each one has a specific purpose.
