Final answer:
When constructing a chart, it's essential to label axes with the variable name and units, such as Time (min) for the x-axis, and choose scales that include all data points. Changing the scale, such as using different percentages on the vertical axis, can influence the interpretation of data. Plot data points by identifying the intersection of the x and y values for each point.
Step-by-step explanation:
Adjusting Chart Axes and Scales
When creating or adjusting a chart, it's essential to clearly label each axis with the variable name and its units. In your case, for the x-axis, you would label it Time (min). The appropriate scale for the x-axis may be from 0 to 70 minutes with a tick mark every 10 minutes, allowing for clear and consistent data plotting.
For the y-axis, to best display the data range, you may choose a scale starting at a low enough value and extending to a high enough value to cover all data points. If your data ranges from 0 km to 160 km, you could set tick marks every 10 km. This scale choice ensures that all the data points are representatively plotted, and none are left out of the graph's bounds.
Changing the axis scale can also have a significant impact on how the data is perceived. For example, adjusting the vertical axis from 0% to 30% can make the variation in the data appear smaller, while a scale from 3% to 10% can emphasize the fluctuations, making them look larger. Therefore, it's important to select a scale that truthfully represents the data while being easy to read.
Once you have set up your axes with appropriate labels and scales, you can begin plotting the data points. For each point, move horizontally to the correct value on the x-axis, then vertically to the corresponding value on the y-axis, and place a dot where these two values intersect. Repeat this process for all the data points to complete your graph.
