It is easy to know what to write in your lab notebook when making quantitative measurements. For instance, you simply record the reading from a balance when measuring plant mass. Still, science also involves collecting qualitative data. What is the best way to describe data that is harder to put into numbers, such as leaf shape or flower color? Many plant scientists have learned to precisely sketch the parts of a plant, but not everyone feels comfortable making conclusions based on their own limited artistic skills. Other people may have color blindness and must depend on their teammates to accurately judge colors. In cases like these, imaging technology can be helpful in collecting objective data.
