l0|HdCorrelation Coefficient Lab
Collect the following data about yourself. Use inches for all measurements.
Foot Length
(L1)Height
L2Arm Span
L3Length from elbow to wrist
L4After the teacher has started the Activity enter your information into the appropriate list and send your information to the teacher.
Once all data has been collected the teacher will send the compiled class data to your calculator. Use the compiled data to answer the following questions.
Use Foot length vs. Height to complete the following.
Draw a scatter plot.
Find the regression equation and the correlation coefficient.
Do you think there is any correlation between a persons foot length and their height? Explain.
Write a word problem for which your equation can be used to make a prediction about a persons foot length or height. Do not use values from the data that was collected. Use your regression equation to solve it. Discuss the accuracy of your prediction.
Use Height vs. Armspan to complete the following.
Draw a scatter plot.
Find the regression equation and the correlation coefficient.
Do you think there is any correlation between a persons height and their armspan? Explain.
