These questions should be completed and put into data set form. Use the rcode given to help you make your plots. Make things neat.
here is some r code to help you along for the first two questions. See if you can parse out what each piece of the code does:
plot(curve(dnorm(x,mean=0,sd=4)),xlim=c(-10,10),ylim=c(0,0.5))
curve(dnorm(x,mean=0,sd=2),add=TRUE)
Questions from the book:
1.109, 1.110, 1.119, 1.122, 1.126 (can draw the curves with your stylus if you would like), 1.132 - 1.140
As review, yet still part of your data set:
1.156, 1.175 (answer each of the questions asked separately)
Questions from me:
1) Find an example of a graph or other visual you think represents data well. In a quick few sentences, explain why you think this is an exemplary piece of visualization.
2) Find an example of a graph you think is not well done. (don't just type 'bad graph' into google--I'll know 'cause I've seen those. Do some searching in an area or place that you are familiar with, be it hobby or study). Explain what the graph was TRYING to do, why you think it failed, and perhaps outline what you think could be changed to fix it.
