The average growth rate of a cypress tree in height is about 4 feet per year. Use the data to create a scatterplot using your calculator. Then answer the question.
Width: 1.3, 4.1, 6.2, 8.9, 12.3
Height: 2.5, 6.1, 10.2, 15.0, 18.7
Which type of correlation does the data resemble?
A) positive correlation
B) negative correlation
C) equal correlation
D) no correlation
To create a scatterplot on a calculator, you can input the data points and plot them using the graphing function.
Using the provided width and height data points:
Width: 1.3, 4.1, 6.2, 8.9, 12.3
Height: 2.5, 6.1, 10.2, 15.0, 18.7
Plotting these points on a scatterplot will show a positive correlation. This is because as the width of the tree increases, the height of the tree also increases, indicating a positive relationship between the two variables.
Therefore, the data resembles a positive correlation (A) in this case.
