Final answer:
After forming a testable question, a scientist would generally design an experiment, analyze the data, and draw conclusions.
Step-by-step explanation:
After forming a testable question, a scientist would generally design an experiment. This involves identifying the factors that will not vary (fixed factors), the independent variable (the variable that is set), and the dependent variable (the variable that will be measured). The experiment should be designed in a way that allows the scientist to collect accurate data and test the hypothesis. Once the experiment is performed and data is collected, the scientist will then analyze the data using statistical, mathematical, and/or graphical methods. From the data analysis, the scientist will draw conclusions about whether the experiment supports or rejects the hypothesis. Finally, the scientist may need to repeat the experiment or have someone else repeat it to verify the results.
