Answer:
independant variable.
Step-by-step explanation:
The IV in science stands for "independent variable". The independent variable is a type of variable in an experiment that is manipulated or controlled by the experimenter. It is the variable that is changed in order to observe how it affects the dependent variable.
In an experiment, the independent variable is the variable that you intentionally change or manipulate to test its effect on the dependent variable. For example, if you want to investigate how different amounts of fertilizer affect the growth of plants, the independent variable would be the amount of fertilizer that you give to each plant. By varying the amount of fertilizer, you can observe and measure how it influences the growth of the plants.
Understanding the concept of the independent variable is important for designing and conducting scientific experiments. By controlling and manipulating the independent variable, scientists can investigate cause-and-effect relationships and make conclusions about the effects of certain factors on the outcome of the experiment.
It is essential to note that the answer provided initially, "independant variable," contains a typographical error. The correct spelling is "independent variable
