__**Monday **__ NOTE: The **independent variable** is the **cause** and the **dependent variable** is the **effect.** When a hypothesis is presented as an **if/then** statement, the “**if”** is the **cause** and the “**then”** is the **effect.** **//Directions: //**Identify all statements in which the **independent variable** is underlined.
 * 1) A. If the milk is left out of the refrigerator**,** then **__it will start to stink__**.
