Classification of Different Types of Tables

(b) Special purpose table: A special purpose table is also called a text table or a summary
table or an analytical table. Such a table presents data relating to a specific problem.
According to H. Secrist, “These tables are those in which are recorded, not the
detailed data which have been analysed, but rather the results of analysis.” Such
tables are usually of smaller size than the size of reference tables and are generally
found to highlight relationship between various characteristics or to facilitate their
comparisons.
2. Classification on the basis of the nature of presented figures: Tables, when classified on the
basis of the nature of presented figures can be (a) Primary table and (b) Derivative table.

(a) Primary Table: Primary table is also known as original table and it contains data in
the form in which it were originally collected.
(b) Derivative Table: A table which presents figures like totals, averages, percentages,
ratios, coefficients, etc., derived from original data.
A table of time series data is an original table but a table of trend values computed from
the time series data is known as a derivative table.
3. Classification on the basis of construction: Tables when classified on the basis of
construction can be (a) Simple table, (b) Complex table or (c) Cross-classified table.

(a) Simple Table: In this table the data are presented according to one characteristic only.
This is the simplest form of a table and is also known as table of first order. The
following blank table, for showing the number of workers in each shift of a company,
is an example of a simple table.
