A conditional statement is usually a sentence written in the form "if 'this,' then 'that'." The "if" part is the hypothesis, and the "then" part is the conclusion.

Conditional statements are also written as "if p, then q," where p represents the hypothesis and q represents the conclusion.

Conditional statements are either true or false.

Examples of Conditional Statements: The hypothesis is bolded and the conclusion is underlined.

The converse statement switches the "if – then", so that as "if p, then q," becomes "if q, then p."
