DATA ANALYSIS
1. Is there a difference in grip strength in your dominant and non-dominant hands? Are you
surprised by the result?
2. Examining the data in Table 3, does there appear to be a correlation between “handedness”
and grip strength? Are the results similar for right-handed and left-handed people?
3. Is there a difference between the grip strengths in the different categories of height for which
data was collected in Table 4? What conclusion can you draw about the relationship between
height and grip strength?
4. Does gender play a more significant role in grip strength than height? than “handedness?”
5. Using the pinch strength data in Table 5, describe the difference in strength between fingers.
Where is the difference the largest?

6. List at least two possible reasons for the differences you see between the pinch strength of
the first two fingers and the second two fingers. In your answer consider actions of the hand
and musculature (Use an anatomy textbook or atlas to view the muscles of the forearm and
hand).
EXTENSIONS
1. Plot a graph of the maximum and average grip strengths for each participant in each category.
Do the results correspond with what you would expect in a human population?
2. Perform daily hand-strengthening exercises to increase your grip and/or pinch strength (such
as squeezing a rubber ball). Measure your grip and/or pinch strength after two weeks and
after four weeks. Compare the results with your original data.
