Question

mr. edwards class is growing a basil plant. for 5 weeks they record the height of the plant. they displayed their data using a bar graph and a line graph. which one was the better display and why? a neither was an appropriate display to use b line graph, it shows change over period of time. c bar graph, it compares things between different groups d bar graph, so you could see the height of the plant each week.

Explanation:

To determine the better display for the basil plant's height over 5 weeks, we analyze the purpose of each graph:

• A line graph is ideal for showing change over time (e.g., growth trends), as it connects data points to visualize progression.
• A bar graph is better for comparing discrete groups, not showing continuous change over time.
• Option A is incorrect because line graphs are appropriate for time - series data (plant height over weeks).
• Option C is incorrect because the data here is about the same plant over time, not comparing different groups.
• Option D is incorrect because while a bar graph can show weekly heights, a line graph is better for illustrating the trend of growth over time.
• Option B correctly states that a line graph is better as it shows change over a period of time.

Answer:

B. Line graph, it shows change over period of time.
