QuestionSomeone has plotted this scatter graph and you are marking their work.
Write down all of the things on the list that would improve their graph.
List of possible improvements
Draw lines between the points
Add units to the axis labels
Make the horizontal axis go up to 40
Make the vertical axis go up to 400
Make all the points different colours
Studdy Solution
STEP 1
1. The scatter graph is intended to show the relationship between the amount of petrol used and the distance traveled.
2. The graph currently has a horizontal axis labeled "Amount of petrol used" going up to 80 and a vertical axis labeled "Distance travelled" going up to 200.
3. The points on the graph are all the same color (green).
STEP 2
1. Evaluate the need for drawing lines between the points.
2. Assess the axis labels for units.
3. Consider the suggested axis range adjustments.
4. Evaluate the color differentiation of points.
STEP 3
Evaluate the need for drawing lines between the points:
- In a scatter plot, lines between points are typically not necessary unless showing a trend or connection is required. Since this is a scatter graph, drawing lines between the points may not be an improvement.
STEP 4
Assess the axis labels for units:
- The axis labels "Amount of petrol used" and "Distance travelled" do not include units. Adding units would improve clarity. For example, "Amount of petrol used (liters)" and "Distance travelled (kilometers)".
STEP 5
Consider the suggested axis range adjustments:
- The horizontal axis currently goes up to 80, and the vertical axis goes up to 200. The suggestion to make the horizontal axis go up to 40 and the vertical axis up to 400 should be evaluated based on the data range and context. If the data points are within the current range, these changes may not be necessary.
STEP 6
Evaluate the color differentiation of points:
- Making all the points different colors would not necessarily improve the graph unless there is a categorical variable to differentiate. If the points represent different categories, using different colors could be beneficial.
Based on the evaluation, the following improvements would enhance the graph:
1. Add units to the axis labels.
