That would be C. The control group is the group where no variable has been changed for it and it’s how something normally would be.
For example if we’re experimenting the effect of excess water on plant growth the plant getting normal amount of water is the control group and the plant getting excess water is the test group(or groups in most cases there is more than one).
You can use the growth of the control plant as a reference of how the growth of the other plant has been affected(wether it has been increased or decreased or stayed the same)
Answer:
A: Draw conclusions about their data.
Explanation:
A important step in the scientific methodology, once the results are analyzed is to draw reasonable conclusions about the whole experiment. For example: if a scientist has studied the effect of salt stress on the growth of plants and he got the results in form of graphs which show that growth of salt treated plants in very less than normal plants. Then he needs to draw conclusion after consulting relevant previous experiments and say that salt stress hinders growth and why? with reasonable logic. This is an important step in the scientific methods which concludes our work and makes it more impact for the upcoming scientists interested to work on problems of similar nature.
Hope it helps!
Answer:
