Final answer:
After experimenting, you should analyze the results and conclude to see if the data supports or rejects the hypothesis. You might then proceed to further testing or develop a new hypothesis based on your findings. (Option D is the correct answer)
Step-by-step explanation:
Once you have carried out your experiment and have some results, you should analyze your results and conclude. This involves considering the data collected during the experiment and determining whether the results support or reject your hypothesis. If the hypothesis is supported, you may proceed to further testing; if it is rejected, you might form a new hypothesis and design new experiments to test it. Sharing your findings with the scientific community through publications and presentations is also an important part of the process.
It is not correct to keep results only if they support your hypothesis or to design a new experiment to test the same results. Nor should you make a new hypothesis to fit your results before analyzing them. Analyzing data critically and drawing conclusions, whether they confirm or negate your initial hypothesis, are essential steps in the scientific method.
