For the bean plant growth experiment, what type of graph would best display the data collected?

The best choice for displaying the data collected from the bean plant growth experiment is a line graph showing the amount of growth each week. This type of graph is particularly effective for illustrating trends over time, making it easier to visualize how the bean plants grow on a weekly basis. By plotting growth measurements at regular intervals, a line graph can clearly demonstrate the progression of growth, reveal patterns, and highlight any fluctuations that occur during the experiment.

The other options serve different purposes and are not as suitable for this specific scenario. For instance, a pie chart is typically used to show the proportion of different categories within a whole, which does not apply to tracking growth over time. A bar graph could be useful for comparing different categories, like soil types, but it would not effectively convey changes over time. A scatter plot is better suited for examining the relationship between two variables, such as temperature and growth, rather than depicting the growth of a single variable over time. Thus, focusing on the growth trend week by week is most effectively represented through a line graph.
