Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
During an experiment, if you purposely change the temperature to test a hypothesis, the temperature is called the ____
A
variable
B
manipulated variable
C
responding variable
D
result
Explanation: 

Detailed explanation-1: -The manipulated variable is the air temperature because it is purposely changed by the experiment to test the hypothesis. The responding variable is the number of cricket chirps because it may change in response to the air temperature.

Detailed explanation-2: -Temperature is a much common type of controlled variable. Because if the temperature is held constant during an experiment, it is controlled.

Detailed explanation-3: -The independent variable is the one that is changed by the scientist. To insure a fair test, a good experiment has only ONE independent variable. As the scientist changes the independent variable, he or she records the data that they collect.

Detailed explanation-4: -The variable that is purposely changed to test a hypothesis is called the manipulated variable (also called the independent variable). The factor that may change in response to the manipulated variable is called the responding variable (also called the dependent variable).

Detailed explanation-5: -Manipulated: The manipulated variable is temperature. One can simply change the temperature by heating or cooling a system.
