Biology
A student in a Living Environment class designed an experiment to investigate if the
number of times a student squeezes a clothespin varies with the hand used. Her hypothesis
was that students could squeeze a clothespin more times in a minute when they used their
dominant hand than when they used their nondominant hand.
During her investigation, she fi rst squeezed and released a clothespin as often as possible
for 20 seconds with her dominant hand. She recorded the number of squeezes in a chart.
She performed three trials before resting. After that, she repeated the entire procedure
with her nondominant hand. Some of the data are shown in the table below.
Calculate the clothespin-squeezing rates per minute and average for the dominant hand. Record the data
in the data table below for all three trials, as well as the average squeezing rate per minute. You should have
four numbers recorded.
