What are the explanatory and response variables in this experiment?

The response variable is the focus of a question in a study or experiment. An explanatory variable is one that explains changes in that variable. It can be anything that might affect the response variable. The response variable is always plotted on the y-axis (the vertical axis).

What is a explanatory variable in an experiment?

In an experimental study, the explanatory variable is the variable that is manipulated by the researcher. Explanatory Variable. Also known as the independent or predictor variable, it explains variations in the response variable; in an experimental study, it is manipulated by the researcher.

What is an example of an explanatory variable?

Explanatory variable is manipulated by the researcher for the given experimental study. For example, consider the two explanatory variables in an experiment are fast food and soda. Many fast food restaurants encourage having soda after intake of food.

What are the explanatory and response variables?

Explanatory vs response variables An explanatory variable is the expected cause, and it explains the results. A response variable is the expected effect, and it responds to explanatory variables.

Where is the explanatory variable?

x-axis
The explanatory variable (or the independent variable) always belongs on the x-axis. The response variable (or the dependent variable) always belongs on the y-axis.

Which is the explanatory variable?

❖ The variable that is used to explain or predict the response variable is called the explanatory variable. It is also sometimes called the independent variable because it is independent of the other variable. In regression, the order of the variables is very important.

What is another name for explanatory variable?

Independent variables are also called “regressors,“ “controlled variable,” “manipulated variable,” “explanatory variable,” “exposure variable,” and/or “input variable.” Similarly, dependent variables are also called “response variable,” “regressand,” “measured variable,” “observed variable,” “responding variable,” “ …

What are the two response variables?

One response variable is the amount of time visiting the site. This response variable is quantitative. One response variable is the amount spent by the visitor. This response variable is quantitative.

What are examples of explanatory variables?

Examples of explanatory and response variables

Is time an explanatory variable?

Time is a common independent variable, as it will not be affeced by any dependent environemental inputs. Time can be treated as a controllable constant against which changes in a system can be measured.

Is gender an explanatory variable?

Examples include explanatory variables, such as gender, ethnicity, type of instruction, etc., and response variables such as individual test item scores, total test scores, and achievement levels.

How do you identify a response variable?

The easiest way to visualize the relationship between an explanatory variable and a response variable is with a graph. On graphs, the explanatory variable is conventionally placed on the x-axis, while the response variable is placed on the y-axis. If you have quantitative variables, use a scatterplot or a line graph.

What is the difference between explanatory and response variable?

Thus a response variable corresponds to a dependent variable while an explanatory variable corresponds to an independent variable. This terminology is typically not used in statistics because the explanatory variable is not truly independent.

What does a ‘explanatory variable’ mean?

An explanatory variable is any factor that can influence the response variable. While there can be many explanatory variables, we will primarily concern ourselves with a single explanatory variable. A response variable may not be present in a study.

What is an example of explanatory variable?

For example, consider the two explanatory variables in an experiment are fast food and soda. Many fast food restaurants encourage having soda after intake of food. Hence, the two variables involved in the study are not independent to each other.

What is an example of a response variable?

The response variable is the variable that you are interesting in making measurements and conclusions on. For example, if you want to measure how well students are learning material one measurement would be their grade (A, B, C, D, F) or another would be percentage (80%, 90%, 95%, etc.).
