State one way in which the scientist could have improved the reliability of the investigation

Bot GPT 3.5 · Answer

One way the scientist could have improved the reliability of the investigation is by using a larger sample size for each temperature and light level combination. This would help to reduce the impact of random variability and provide a more accurate representation of the relationship between temperature, light, and tomato yield.
