Independent and dependent variables: Practice worksheet.

Variables are given a special name that only applies to experimental investigations.One is called the dependent variable and the other the independent variable. The independent variable is the variable the experimenter changes or controls and is assumed to have a direct effect on the dependent variable.

In an experiment, there are independent variables (IV) and dependent variables (DV). The IV is something the researcher has control over and is the variable being manipulated or changed.

An experiment consists of two groups; an experimental group and a control group. The control group serves as a comparison and no variables are changed in it. In the experimental group the.

In any experiment, the variables are classified as either control, independent or dependent. Control variables are those that are to changed and hence controlled. Independent variables are those that are changed and we study the effect of changes in these variables.

Independent and dependent variables are the variables that change during the course of an experiment. An example might be an experiment on how temperature affects plant growth.

Variables Vary: Any scientific experiment is based on the comparison between the effect of chosen treatments on at least two samples. These samples undergo at least one treatment which is called a variable because it varies according to the needs of the experiment.

Identifying Variables Worksheet Instructions: For the following experiments, identify and describe the (IV) independent variable, (DV) dependent variable, (CG) control group, and (Con) the constant. 1) Different rose bushes are grown in a greenhouse for two months.

The independent variable is the variable that is controlled and manipulated by the experimenter. For example, in an experiment on the impact of sleep deprivation on test performance, sleep deprivation would be the independent variable. The dependent variable is the variable that is measured by the experimenter. In our previous example, the.

This is very important because the whole point of your experiment is to determine if there is a relationship between the independent and dependent variables. If you can say with certainty that the changes in the dependent variable were caused solely by the independent then you cannot draw conclusions from your experiment and thus make predictions.
