University of California Irvine Presenting Data Discussion

 

  • Your data file must have at least 300 observations .   
  • Data must have at least two numeric variables that you think might have an association with each other.  One of these will be your response variable (y) and the other your explanatory variable (x). 
  • You may choose data from any source that interests you.  Here are a couple of sites where you might find suitable data (not all data is suitable – see me if you’re not sure).  You might also google something like “free small dataset csv download”

Once you have identified your data, post the following:

  • Where did you find this data (exactly – include the URL) and what does it represent?
  • What two numerical values will you be looking at? 
  • Do you expect there will be a relationship between these variables?
  • Create a scatterplot and compute the correlation value for these two numerical values
  • Write a 2-3 paragraph describing the association (or lack thereof) between your two numeric variable
