ANSWER:
The Variables and Hypothesis play an extremely important part in research. Variables and Hypothesis are connected inversely. A hypothesis is used in an experiment to define the relationship between two variables. The purpose of a hypothesis is to find the answer to a question ( which is basically why this experiment is being conducted). An example of variables (dependent, independent and control) is when you want to test which kind of soil will help plants grow the fastest, you have three kinds of soil, A,B, and C. So, the independent variable is the kind of soil, the dependent variable is the length of the plant and the control variable is the sunlight, because that has to stay the same for everything.
EXPLANATION:
The Variables and Hypothesis play an extremely important part in research.
Variables and Hypothesis are connected inversely. A hypothesis is used in an experiment to define the relationship between two variables. The purpose of a hypothesis is to find the answer to a question ( which is basically why this experiment is being conducted)
For instance, if the experiment is to see what kind of fertilizer will help plants grow the fastest, and there's three different brands, brand A, B, and C, your hypothesis could be something like this: Brand C will help plants grow the fastest.
Now, let's talk about variables, there's a few different kinds: (these are the main kinds)
Independent Variables: you can think of this like the x variable, it doesn't depend on anything, but instead, the dependent variable depends on the independent variable.
Dependent Variables: you can say that the dependent variable is the y value, it depends on the x, just like the d.v. depends on the i.v.
Control Variables: control variables are the factors that stay the same throughout the experiment.
