IV: Amount of water
DV: Height of the strawberry plant
CG: The fourth strawberry plant
Con: Type of strawberry plant, type of water given, type of soil used, amont of sunlight.
Explanation:
When you say <u>independent variable</u> this is the variable in a study that you change or manipulate. In this case, the amount of water is the one that is changing per plant. This is done to test whether this variable will have an effect on another.
The <u>dependent variable</u> is the variable that is not changed by the researcher or scientist. The changes in this variable is what you'd like to take note of. The changes that the dependent variable "depends" on the indepedent variable. This means that the dependent variable is the one affected. In this case, it would be the height.
<u>Control Group </u>is the group that you are not going to test with the Independent variable. We do this to determine or rule out any other intervening variables that may cause a change. If the result of the study would be that there is not difference between the other group and the control group, then that would mean that the independent variable may not have had any effect on the dependent variable. Another purpose to a control group is to provide also a baseline to track changes.
<u>Controlled variables </u>are variables that are kept constant. This is also to eliminate or prevent other variables from interfering with the results. It ensures that only the independent variable is what is causing the change. If there were no controls to this particular experiment, you will not be able to properly conclude that it is indeed the amount of water that is causing the change.
