1/2/2024 0 Comments Box plot calculator![]() ![]() The drug company wanted to see which of the 2 vitamins had the greatest impact on lowering people’s cholesterol. All 30 people had cholesterol levels between 8 and 10 before taking one of the vitamins. In addition, 15 different people were randomly chosen to take Vitamin Y for 2 months and then have their cholesterol levels checked. In the study, 15 people were chosen at random to take Vitamin X for 2 months and then have their cholesterol levels checked. A new drug study was conducted by a drug company in Medical Town. This would, therefore, mean that the times are more predictable and reliable.Ģ. Since the range for the driving times is smaller, it means the times to arrive by car are less spread out. For the bus times, the range is 32−12=20 minutes. The range for the car times is 17−8=9 minutes. Using the medians, 50% of the cars arrive at school in 11 minutes or less, whereas 50% of the students arrive by bus in 17 minutes or less. When plotted, the box-and-whisker plots look like the following: Use the double box-and-whisker plots to compare the times it takes for students to arrive at school either by car or by bus. Emma and Daniel collected the following data:īus times (min) 14 18 16 22 25 12 32 16 15 18Ĭar times (min) 12 10 13 14 9 17 11 10 8 11ĭraw a box-and-whisker plot for both sets of data on the same number line. There were those who drove their own cars to school, and there were those who took the school bus. There are 2 main groups of commuters who were in the survey. Emma and Daniel are surveying the times it takes students to arrive at school from home. Sense of both the median and the spread of our data.\)ġ. That, we have the range that goes well beyond that or howįar the total spread of our data is. Have a plot like this, just visually, youĬan immediately see, OK, what is the median? It's the middle of And I can do this in a differentĬolor that I haven't used yet. The box and whisker plot essentially show us And then our boxes,Įverything in between, so this is literally the The third quartile from the fourth quartile. Halfway between, well, halfway between 10 and 15 is 12.5. Separating the first quartile from the second quartile, theįirst quarter of our numbers from the second That we would attempt to represent with the box. Represent this data right over here, so the data between the We want to think aboutĮssentially represents the middle half of our data. Want to think about- there's several ways to draw it. Out all of the information we need to actually Mean of these two numbers, 11 plus 14 is 25. Numbers are going to be this 11 and this 14. Looking for a median, you have two middle numbers. Than these two, three numbers greater than it. So the two middle numbersĪre this 2 and this 3, three numbers less Median of these numbers? Well, we have 1, 2, 3, 4,ĥ, 6, 7, 8 data points. So if we look at this firstīottom half of our numbers essentially, what's the Separately at this set and look separately at this set. Take our median out and have the sets that are left over. Now, when we're trying toĬonstruct a box and whisker plot, the convention is, Numbers larger than it and 8 numbers smaller than it. Straightforward to find the middle of our Take the median of something, it's really helpfulĪttempting to order our data. ![]() And to do that, we need toĬome up with the median. So let's actually try toĭraw a box and whisker plot. So what a graph capturesīoth of that information? Well, a box and whisker plot. Of graph he should create, that might be a littleīit more straightforward than the actual creation of the Should he create? So the answer of what kind That people traveled or that people travel. The spread of distances and the median distance Spread of the distances- this is a key word. Wants to find out more about where his patronsįollowing distances traveled. ![]()
