Which is the best way to display this data for analysis?

| Avg. Plant Height (cm) | Avg. Growth (cm) |
|-------------------------|------------------|
| 0 | 2 |
| 1 | 3 |
| 2 | 6 |
| 3 | 9 |
| 4 | 14 |

A. Place the data in a chart that includes individual measurements before averages were calculated so the information is more complete.
B. Transfer the data into a pie chart with five sections, one for each week, that are sized based on plant growth for that week.
C. Use the first column of data for the x-axis and the second column for the y-axis and plot the data in a line graph to show the growth trend.
D. Use the first column of data for the y-axis and the second column for the x-axis and plot the data in a line graph to show the growth trend.



Answer :

To determine the best way to display the given dataset for analysis, let's examine each option step by step:

1. Place the data in a chart that includes individual measurements before averages were calculated so the information is more complete:
- Although detailed data can provide more information, this doesn't directly show the trend or pattern in the data. For visualization purposes, a more straightforward representation like a graph might be more effective.

2. Transfer the data into a pie chart with five sections, one for each week, that are sized based on plant growth for that week:
- A pie chart is used to show parts of a whole. Since the data represents a trend over time (plant height growth), a pie chart isn't the best choice here. It doesn’t effectively show change over time or trends.

3. Use the first column of data for the [tex]\( x \)[/tex] axis and the second column for the [tex]\( y \)[/tex] axis and plot the data in a line graph to show the growth trend:
- By using the average plant height (cm) on the [tex]\( x \)[/tex] axis and average growth (cm) on the [tex]\( y \)[/tex] axis, you can effectively visualize the trend of growth. A line graph would clearly demonstrate how the average growth changes with plant height over time.

4. Use the first column of data for the [tex]\( y \)[/tex] axis and the second column for the [tex]\( x \)[/tex] axis and plot the data in a line graph to show the growth trend:
- Inverting the axes would make the interpretation less intuitive. Typically, time or progression-related variables (like height as it grows) are placed on the [tex]\( x \)[/tex] axis to make it easier to understand how one variable influences another over time.

After evaluating each option, the best way to display the data for analysis is to:
- Use the first column of data for the [tex]\( x \)[/tex] axis and the second column for the [tex]\( y \)[/tex] axis and plot the data in a line graph to show the growth trend.

Therefore, the correct approach is:
Use the first column of data for the [tex]\( x \)[/tex] axis and the second column for the [tex]\( y \)[/tex] axis and plot the data in a line graph to show the growth trend.

Thus, the correct answer is: 3.
