3 1. Describe the results of this experiment. The results from this experiment are the first and second wheat plants grew the most in 8 weeks, with the height of 20 cm. The third wheat plant grew the least in 8 weeks, with the height of 14 cm. The graph shows the growth of these wheat plants as they grew over an 8 week period. © 2016 Carolina Biological Supply Company

6 2. If you wanted to compare the data in Activity 1 to the data in Activity 2, how might you do this? If I were to compare the data in Graph 1 to the data in Graph 2, I would use a scatterplot with linear lines. I would do this to compare the lines of best fit for the graph information to compare the two data sets. © 2016 Carolina Biological Supply Company
7 Data Data Table 1 Wheat Plant Trendline Equation Wheat Plant 1 trendline equation Y=1.238x + 0.9286 Wheat Plant 1 trendline corrected Y=1.402 Wheat Plant 2 trendline equation Y=1.0595x + 1.6071 Wheat Plant 2 trendline corrected Y=1.3431x Wheat Plant 3 trendline equation Y=1.0357x – 0.2857 Wheat Plant 3 trendline corrected Y=0.9853 3. Based on the corrected trend lines, which wheat plant grew fastest? Based on the corrected trend lines, the wheat plant that grew the fastest was the wheat plant 1. This line is the largest line, which shows the greatest slope. 4. Why do you set the y-intercept to 0? I set the y-intercept to 0 because all of the plants were grown from seeds, so the height at week 0 would be 0. The y-intercept indicates the height at week 0 at 0. ******* The pictures included list a date from October of 2023 as I took microbiology and a lab similar to this was included in the class*** © 2016 Carolina Biological Supply Company
