Construct a time series plot for students in grade 12, and comment on any trend over time. Construct a time series plot that shows trends over time for each of the three grade levels. Graph each of the three-time series on the same set of axes, using different colors to distinguish the different grade levels. Either label the time series in the plot or include a legend to indicate which time series corresponds to which grade level. Write a paragraph based on the plot from Part (b).

Looking at year-to-year trends, they found that the average age at first use had increased for 12 out of 18 drugs, including alcohol, cocaine, ecstasy, hallucinogens, heroin, inhalants, LSD, marijuana, stimulants, and tobacco products such as cigars, cigarettes and smokeless tobacco. For the other six drugs— crack cocaine, methamphetamines, opioids, PCP, sedatives, and tranquilizers—they found no statistically significant changes in the age at first use.” Write one or two sentences interpreting the bold finding at the end of the paragraphAre the data displayed in the graph above discrete or continuous? What is the level of measurement of the data? Are the data above time series or cross-sectional data? Examine the data for each race/ethnicity group.
