A complex table represents ____________.
(A) Only one factor or variable
(B) Always two factors or variables
(C) Two or more factors or variables
(D) All the above

Hint: In this question, we have to choose the correct option for the particular required.
We need to consider the definition of the complex table and then find out the option which is absolutely true.

Complete step-by-step solution:
We need to find out the correct option for a complex table.
A complex table is one which shows more than one characteristics of the theta.
A table is an arrangement of data in rows and columns, or possibly in a more complex structure. Tables are widely used in communication, research, and data analysis.
A complex table summarizes the complicated information and presents them into two or more interrelated categories. For example, if there are two coordinate factors, the table is called a two-way table or bi-variety table; if the number of coordinate groups is three, it is a case of three-way tabulation, and if it is based on more than three coordinate groups, the table is known as higher order tabulation or a manifold tabulation.

$\therefore $ The option (C) is the correct answer.

Note: In a complex table (also known as a manifold table) data are presented according to two or more characteristics simultaneously. The complex tables are two –way or three-way tables according to whether two or three characteristics are presented simultaneously.
Complex tables are three types
Double or Two-way table
Three-way table
Manifold (or higher order) table.
