Question
Correlation coefficients equal to or larger than ± 0.775 are considered that accounted for at least 60 percent of the variation(0.775 z x 100) between comparisons. Negative coefficients exceeding - 0.775 were obtained for correlations between light reLEAF MESOPHYLLS OF TWENTY CROPS 3flectance and percent leaf-water content for sugarcane at 1,450-,1,650-, and 2,200-nm. ; for corn at 550- and 1,450-nm. ; for pigweedat 1,450-nm.; and for tomato at 1,450- and 2,200-nm.
Solution
The text provided discusses the correlation between light reflectance and percent leaf-water content in various crops. A correlation coefficient of ± 0.775 or higher indicates that at least 60% of the variation between comparisons is accounted for. In this case, negative coefficients exceeding -0.775 were found for correlations between light reflectance and percent leaf-water content for sugarcane at 1,450-,1,650-, and 2,200-nm wavelengths; for corn at 550- and 1,450-nm wavelengths; for pigweed at 1,450-nm; and for tomato at 1,450- and 2,200-nm. This suggests a strong negative correlation between light reflectance and leaf-water content at these specific wavelengths for these crops.

Which of the following would be a good prediction for an experiment exploring how rainy days are related to photosynthesis?If photosynthesis is measured in plants over the course of many days that vary in the amount of rain, there will be a negative correlation between the amount of rain and the rate of photosynthesis.When it is rainy, plants have lower rates of photosynthesis because they have less light energy available.If photosynthesis is measured in 100 plants over the course of 100 days that vary in the amount of rain, there will be a negative correlation between the amount of rain (mm) and the rate of photosynthesis (change in plant mass in grams).If photosynthesis is measured in 100 plants over the course of 100 days that vary in the amount of rain, there will be a difference in the rate of photosynthesis over those 100 days.
Consider your investigation into the drought resistance of GM corn. You have several options for arranging the three groups of plants in the greenhouse. One of the options would expose Group 1 to more sunlight than the other two groups.Explain why this would reduce the validity of your investigation.
