Homework 1

Post date: May 16, 2013 9:31:48 PM

Dear All,

Here is the first set of homework, which is related with our Unit 1 (Descriptive Statistics).

Assignment date: 5/16/2013 (Thursday)

Due time: 5/29/2013 (Wednesday) class time.

Bring your homework to the class and turn it in before the class is over. No late homework!

Instruction:

1) Since the small data sets given in the problems are not so small, you still need to use Rstudio to do the calculation. You could just store the data in a txt file first, and then do it as we did in the first in-class activity. You could also use the following code to get the data into Rstudio:

For example, the data set={1,2,3,5,7}, then type in Rstudio like:

data=c(1,2,3,5,7)

2) Print out the homework and write the answers in the blank. If it asks for the plots, just print them and attach them at the end of the homework.

If you have any questions, please come to my office hours.
