Question 15 • CA-Life Science B (High School)
With more plants, one inaccurate height measurement has less influence on the overall results, so B is correct. A larger group also makes the average height less sensitive to a few unusually short or tall plants, which supports D. If one plant dies, it represents a smaller share of the group, so its loss is less likely to disrupt the experiment, making E correct. More plants do not increase sampling error or automatically make calculations easier.
