Explanation:

To draw a valid conclusion in an experiment, one must analyze the collected data. Comparing the heights of the plants under different - colored lights and looking for patterns in the data helps in understanding the impact of light color on plant growth. Measuring only one plant is not representative, ignoring results is not scientific, and choosing a favorite color is subjective and not based on data.

Answer:

Compare the heights and look for patterns in the data
