Solution 1
Solution 2
When planning your data collection, it is important to select controls that:
Are meaningful to the test data.
Explanation:
Controls are an essential part of experimental design. They provide a baseline or standard against which the experimental results can be compared. Therefore, it's important to select controls that are meaningful to the test data. This means that the controls should be relevant and comparable to the experimental conditions, so that any differences observed can be attributed to the variable being tested, rather than other factors. Controls that provide the best contrasts or require no analysis may not necessarily be meaningful or relevant to the test data, and collecting controls at a later time could introduce additional variables that could affect the results.
