Final answer:
The AVERAGE plant height in a data table for an experiment studying radish seedling growth under various light colors would be placed in the last column, after individual weekly measurements, to clearly show the progression and facilitate data analysis.
Step-by-step explanation:
In an experiment measuring the growth of radish seedlings under different colors of light, the AVERAGE plant height would typically be placed in the last or right-most column of a data table. This position is common because it allows for the individual data points (such as weekly measurements) to be listed first, making it easier for readers to see the progression over time before arriving at the average. Gathering these measurements in a logical order facilitates data analysis and interpretation.
In the context of the experiment described, the initial columns would include the independent variable (color of light), followed by the dependent variable (height of plants) recorded at each weekly interval. Once all individual measurements are listed, the final column would present the average height of the plants, calculated from the weekly measurements. This organization provides a clear and systematic overview of the data collected and helps highlight the results of the experiment.
Such table formatting is important for data analysis and to draw conclusions regarding the effect of different light spectra on plant growth, potentially indicating the effect of specific wavelengths of color on photosynthesis and growth rates within the context of this biological study.
