Activity 4: Data Analysis 1. Determine the average growth rate of the wheat plants by averaging the heights for each week and plotting them. Determine a corrected trend line as was done in Activity 3 step 7. 2. On the same plot you made above, determine the average growth rate of the rye plants. Include a corrected trend line. (Remember data for rye plants are in Table 1.) 3. On each of the plots you have made, be sure to include the correlation coefficient (R2) for the trendline. How this is done varies by program, but you can generally do this by right- clicking on the trendline label, then select "format trendline". In the new menu that opens up, check the box that says, "Display R-squared value on chart". a. The R2 value tells you how good a fit your trendline is for your data. The closer the R2 value is to 1, the better the fit. 4. Evaluate: which plant type (wheat or rye) appears to have grown the fastest? Explain how you can tell. 5. Consider: what further data analysis (not experimentation) could be done to have more confidence in determining which plant type grows fastest
