Transcript text: How many variables are included in the scatterplot in Figure 1 (a)? Estimate the range for Variable1 and for Variable2.
There are 2 variables in the scatterplot.
The range for Variable 1 is 24
Solution
Solution Steps
Step 1: Determine the number of variables in Figure 1(a).
Figure 1(a) shows a scatterplot with Variable1 on the x-axis and Variable2 on the y-axis. These are the two variables being compared.
Step 2: Estimate the range for Variable 1.
The minimum value for Variable 1 is approximately 12, and the maximum value is approximately 30. The range is the difference between the maximum and minimum values.
Range = Maximum - Minimum
Range ≈ 30 - 12 = 18
Step 3: Estimate the range for Variable 2.
The minimum value for Variable 2 is approximately 60, and the maximum value is approximately 140. The range is the difference between the maximum and minimum values.
Range = Maximum - Minimum
Range ≈ 140 - 60 = 80
Final Answer
There are \(\boxed{2}\) variables in the scatterplot. The range for Variable 1 is \(\boxed{18}\). The range for Variable 2 is \(\boxed{80}\).
