First dataset for use with Stata

Description: pwstork.gif(click here for a Disney memory)

An examination of historical data from the turn of the century provides us with information regarding the number of stork sitings along with the number of births for 13 cities in Northern Europe (see Table). We have been asked to provide an analysis of these data. As part of this work, we need to present the mean, median, mode, variance, standard deviation, minimum, maximum and range for the two variables. (Excel dataset provided here). If you click on that link, the Excel worksheet should open in Excel for you.) The Stata dataset can be loaded here.

A prominent ethno-statistician claims that stork sitings and babies are obviously related.

What is the correlation between these two variables? What does it mean?

Second dataset for use with Stata

Here is a link to a dataset that provides detail on automobiles and MPG. Play around and look at descriptive statistics for a number of the variables.

 

What is the mean, median, min, max, range, variance and SD for MPG and weight?

 

What is the correlation between MPG and weight?

 

 

Work in groups if you would like.

Have fun. We can discuss any issues you have at 3:00 in room G4.
