Question

When do you identify your variables?

1. After the results
2. After the conclusion
3. Before the hypothesis
4. Before the question

Answer 1

In the scientific method, variables are identified before the hypothesis is formed.

Step-by-step explanation:

In the scientific method, variables are identified before the hypothesis is formed. The steps of the scientific method are as follows:

1. Make observations.
2. Identify a question based on the observations.
3. Research existing sources to find out what is already known.
4. Formulate a hypothesis.
5. Design an experiment to test the hypothesis.
6. Identify the fixed factors and the independent and dependent variables in the experiment.
7. Collect data accurately and interpret the data.
8. Draw conclusions based on the results of the experiment.
9. State the decision and write a conclusion in a complete sentence.
10. Verify the results by repeating the experiment or having it replicated by others.

Therefore, the correct answer is option 4: Before the question.

Answer 2

3. Before the hypothesis

Step-by-step explanation:

In an experiment, variables are the factors that are influencing a certain condition.

Generally, variables can be separated into three groups:

- Dependent variables

Dependent variables are the things that will be measured during an experiment

- Independent variables

Independent variables are the things that will be used to measure the dependent variables.

- Control variables

Control variables include all variables that will remain the same/constant throughout the experiment even when the independent variables are changed.

Before making the hypothesis that will explain researchers' calculated guess on why a certain condition is occurring, they need to identify each of variables that they will use to test their hypothesis. This will help them validate their hypothesis and aid them in forming conclusions by the end of the research/
