The primary objective of experimental methodology is:

The primary objective of experimental methodology is to determine causality. This means that it aims to understand the cause-and-effect relationship between variables. Here are the steps:

1. Formulate a Hypothesis: This is a prediction about the relationship between variables. For example, "Eating breakfast leads to better academic performance."

2. Design the Experiment: This involves deciding how to manipulate and measure the variables. For example, you might have one group of students eat breakfast and another group skip breakfast, then compare their academic performance.

3. Conduct the Experiment: This involves carrying out the experiment and collecting data. In our example, this would involve having the students eat or skip breakfast and then measuring their academic performance.

4. Analyze the Data: This involves using statistical techniques to determine whether the results support the hypothesis. For example, you might use a t-test to compare the academic performance of the breakfast and no-breakfast groups.

5. Draw Conclusions: Based on the data analysis, you decide whether the results support the hypothesis. If the breakfast group performed significantly better, you might conclude that eating breakfast does lead to better academic performance.

6. Report the Results: Finally, you write up the results in a report or academic paper, explaining your methodology, data analysis, and conclusions.
