Astudent is writing his procedure for his science fair project. his teacher reminded him that his experiment should include repetition and should be replicable. here is the procedure he came up with to determine which brand of diaper is the most absorbent: 1) purchase 5 different brands of diapers and measure their weight. 2) have baby sister wear each diaper for 1 hour. 3) measure the weight of the diaper after 1 hour to see how much liquid it absorbed. 4) do the experiment again every day for a week. 1) q: a: does the student's proposed procedure include repetition? why or why not? a) yes, the experiment includes repetition because the student tests 5 different brands of diapers. b) yes, the experiment includes repetition because the student performs the experiment multiple times. c) no, the experiment does not include repetition because the student only tests the diapers on his sister and not any other babies. d) no, the experiment does not include repetition because the student only has the baby wear the diaper for 1 hour at a time instead of repeating the experiment with different time periods. 2) is the student's experiment replicable? why or why not? a) yes, the student's experiment is replicable since he performed the experiment a total of 7 times. b) yes, the student's experiment is replicable because any other student could easily follow his procedure. c) no, the student's procedure is not replicable because it is too complicated for someone else to repeat it. he should have limited it to one brand of diaper and only done the experiment for one or two days. d) no, the student's procedure is not replicable because it depends on too many outside factors that can't be controlled, such as how much his sister had to drink or if she even went to the bathroom during the one hour.
