Batman vs. The Penguin Debate
Due Thursday! Watch “Batman vs. The Penguin Debate.” (Link follows, or check MyD.)
Answer these five questions in a new entry on your WordPress blog (call it “Batman vs. The Penguin Debate”):
1. What is The Penguin’s main idea? What are his reasons?
2. What evidence does he use to support his reasons?
3. How does Batman start his rebuttal? (When two people debate, one of them makes an argument, followed by a rebuttal from the other person. The rebuttal basically states, “No, you’re wrong, and this is why.”)
4. What kind of tactics to you think are fair or unfair in debating, based on this example?
5. Who seems to have the best manner? Why?

Checkpoint 9AProblem 939
Displays of Data: Histograms and Box Plots 
Answers to problem 939:  
HistogramsA histogram is a method of showing data. It uses a bar to show the frequency (the number of times something occurs). The frequency measures something that changes numerically. (In a bar graph the frequency measures something that changes by category.) The intervals (called bins) for the data are shown on the horizontal axis and the frequency is represented by the height of a rectangle above the interval. The labels on the horizontal axis represent the lower end of each interval or bin.
Example: Sam and her friends weighed themselves and here is their weight in pounds: 110, 120, 131, 112, 125, 135, 118, 127, 135, and 125. Make a histogram to display the information. Use intervals of 10 pounds. 

Solution: See histogram at right. Note that the person weighing 120 pounds is counted in the next higher bin.  
Box PlotsA box plot displays a summary of data using the median, quartiles, and extremes of the data. The box contains the “middle half” of the data. The right segment represents the top 25% of the data and the left segment represent the bottom 25% of the data.  
Example: Create a box plot for the set of data given in the previous example.  
Solution:Place the data in order to find the median (middle number) and the quartiles (middle numbers of the upper half and the lower half.)
Based on the extremes, first quartile, third quartile, and median, the box plot is drawn. The interquartile range IQR = 131–118 = 13. 

Now we can go back to the original problem.  


Here are some more to try. For problems 1 through 6, create a histogram. For problems 7 through 12, create a box plot. State the quartiles and the interquartile range.

Land vs. Sea Breezes
1. Click here or here to see an animation about when each occur.
2. Read the following, Land and Sea Breezes, up to the two diagrams. Use the diagrams to help you understand this process.
3. Using the animation, the reading, your knowledge of convection currents and your knowledge of how winds are formed write the following:
 One paragraph explaining how and when sea breezes are formed near land.
 One paragraph explaining how land breezes are formed by the sea.
4. Diagram the two scenarios – one during the day and one at night.
