Identify the independent and dependent variable.

A researcher is studying relationship between speed of cycling and the presence of people. Formulate a relevant hypothesis and identify the independent and dependent variable.

Expert Solution

• Variable: It is any stimulus or event which varies or can take on different values can be measure e.g weight, height

• Hypothesis : It is a tentative and testable statement which expresses relation between two of or more than variables, e.g those who are rewarded shall require lesser number of trials to learn than those who are not rewarded

• Independent variable: It is the variable which is systematically manipulated or altered in an experiment. It is the cause.

• Dependent variable: It is the variable that is measured in an experiment. It is the effect.

• As per the question : Hypothesis: Presence of others will enhance the speed of cycling.

Independent variable:Presence of others

Dependent variable: speed of cycling

Independent variable : It is the variable which is systematically manipulate or altered in an experiment.
