To check the validity of the results for the garlic extract in the second
investigation, a student searched the scientific literature for similar studies. She
found data for the antibacterial effect of onion (Allium cepa), which is closely
related to garlic (Allium sativum). The data for onion extract are shown below.
Complete the table for the garlic extract in the second investigation by writing in
the mean you calculated in c(i).
What does this information suggest about the validity of the results for the garlic
extract?
what do they mean by validity?
