Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
The VARIABLE is:
A
A specific aspect or factor that is changed in an experiment
B
A useful generalization formed through the accumulation of data
C
A specific aspect or factor that remains constant in an experiment
D
Bits of information that are gathered and recorded during an experiment
Explanation: 

Detailed explanation-1: -A variable is anything that can change or be changed. In other words, it is any factor that can be manipulated, controlled for, or measured in an experiment. Experiments contain different types of variables.

Detailed explanation-2: -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-3: -In an experiment, the factor that we measure is called the independent variable. For example : If in an experiment we measure length of the object to calculate its volume, here length is the independent variable. Was this answer helpful?

Detailed explanation-4: -A dependent variable is the one which we can test in a scientific experiment, in order to get its values. The dependent variable is obviously ‘dependent’ on the independent variable. Hence as the experimenter changes the independent variable, we can now observe and record the change in the dependent variable.
