Okay. What we want to go ahead and do is, um we have the following graph, and I'll show you the graph in a minute. Um, that shows, um, the percent of eight, 10th and 12th grade, um, graters who have used marijuana in their lifetimes. Um, and what we want to do is for each of them we want to find the average annual rate of change in percent of, and we want to do it for, um, eighth grade over some time periods. And they wait 10th graders and 12th graders, and we want to kind talk about the similarities and differences. And so here the trends, the bottom line is tthe e eighth graders. Um, then we have the 10th graders. Then we have the 12th graders, and this graph is from 2007 to 2013. And so this actually shows percents from 2007 to a 2013. And this is 10% 20% 30% and 40%. Um, And so, um, let's go ahead. And, um, let me go ahead and hit some values here for you, so we can actually see some values. Um, better. So l'm doing is Dismas is pretty good. It lets me click on the points, and you can see what they're actually are. Um, and so what this is telling me, is a pier 42% of 12th graders in the year 2007 had used marijuana. Um, And then, um, whereas in 2007 only 14.2% of eighth graders had used marijuana. Um, and so what we want to do is we want to find the average annual rate of change in percent of eighth graders from the first time from 2000 and 72 um, 2010. Okay, in so in 2010 it was 17.3% of eighth graders minus the 14.2, um, percent. And then divide by three. Cause there's her three years difference. And so there This tells me there's a one point 03 percent increase per year in eighth graders who said they have used marijuana, and then what we're gonna do, um, is now we want to do it for 2000 and 10 to 2013. Um, and so 2013 was 16.5 minus, um, the 2010 which was 17.3, and there's a three year difference. And so this is a negative point for 3% per year. So that means in the years between 2010 and 12 13 there was actually a 130.43% decrease in eighth graders who said per year who said they used marijuana and then we want to do from 20 um, 7 2002 2013. And so we have the 17.3 minus the 4.14 point two over six years, and there is a 0.52% per year increase. Okay, so that is, um, for eighth graders. And now we want to do it for 10th graders and we want to do the same years. We want to go from 2007 to 2010 and so we have for them. We have 33.4 minus a 31 um, over three, and this was a 0.8% increase per year. We want to go from 2010 clips. 2010 to 2013. Um, and this was 35.8 minus the 31 divided by the three years. Um, and this once again, is an 8% of 80.8% per year increase. Um, And now we're gonna go from the entire 2007 to 2013 to the entire six years, and we get the 35 0.8, um, minus the 31 over six, and once again, a 60.8% per year increase. So it looks like for 10th grade, um is pretty consistent increase. And so now we want to do it for the 12th graders, and we want to do the exact same. So we want to go from 2027 the year 2007 to 20 10 and we have 43.8, minus the 41.8 divide by the three years and 0.67% per year increase. And then we, um, go from 2010 to 2013 and we have 45.5, minus the 43.8. Divide by three in a 0.57% per year increase. And then we go through the entire six years. So we go from 2007 to 2013 and so we have 45.5, minus the 41.8 and divide by six, and that's 60.62% per year. Okay, um and so what? I'm gonna go ahead and do is go ahead and go to the next slide and kind of put this all in kind of perspective. So this is eight. Um, this is Ted, and this is 12. And we have from 20 2007 to 2010 2010 to 2013 and then 2007 to 2013. Um and so we had one point. 03% per year. We had a negative 0.43 percent in a 0.52 in 10th grade. It was consensus, it of 0.8 percent per year. And in 12th grade, 0.67 um, 0.57 and 0.62%. Okay. And so let's talk about the similarities. Um, and so we can also, um, So the similarities, um, or that, um, except for this eighth grade. Um, So the tent and 12th graders, um, have a pretty much consistent, um, percent increase, cause all of these air about 0.6 and these air 0.8 increase, um um, per year for the years. Um 22,007 to 20 13. Um, there are pretty consistent percent increase per year for those years from 2007 to 2013 wth e eighth graders. Um, but the eighth graders, um, have a huge increase. Um, in usage from 2000 and seven to 2010 of 1.3% per year, um, and then drops off to a negative 0.43%. Um, per year, um, from 2010 to 2013. Um And so, um, we do know in the years from 2010 to 2013 we pretty much had legalization of marijuana. Um, And so, um, why the drop off could be because, um, for eighth graders, um, it might b'more for the thrill of doing something illegal, and so that legalization of marijuana might have kind of, um, deterred them. Um, it's not kind of fun anymore. Also in this time also came vaping. Um and so that could have been a distraction as well for eighth graders. So, um, those were just kind of some things I saw. You could probably add more to it. Um, and this is kind of really, um right here is kind of a little bit more of a subjective explanation. Um, so you can kind of feel in with your own thoughts
