A researcher assessed the effects of a new drug on migraine headaches. One sample of migraine sufferers received a placebo pill (0 milligrams of the drug) every day for a month.  A second sample received a 10-mg dose of the drug daily for a month, and a third sample received daily doses of 20-mg. The number of headaches each person had during the month was recorded.  The results are summarized in the following table:  The Mean Number of Migraines During Drug Treatment Dose of Drug (in mg) Mean Number of Migraines SE 0 28 5 10 12 4 20 5 2 What is the independent variable (IV)? How many levels do we have for the IV? What is the level of measurement for the IV? What is the DV (remember, the DV is the data)? What is the level of measurement of the DV? What is the best graph to display this data? Explain. Construct a graph (by hand) that incorporates all the information in this table. Looking at your graph, do you think that the new drug treatment really worked. Explain your answer.
