Correlations were performed to investigate the relationship
between different types of grips and time taken to open the packs
and are outlined in Table 3. Results for the water bottle indicated a
large correlation between dominant grip and shorter opening times
as well as a medium correlation for non-dominant grip. Medium
correlations were also found for both dominant and non-dominant
grips and shorter opening times for biscuit portions, indicating that
stronger grips are important for successful and efficient opening of
these products.
