* NLS Work
*----------------------

* Setup:  read the data into Stata with these commands.
*    (You will need to "clear" any previously loaded data, first.)
use http://www.stata-press.com/data/r12/nlswork.dta
keep if year==68

* Problem 0
*----------
* Save your results in a log file.

* Problem 1
*----------
* Among the women interviewed in 1968, what proportion had less
*   than an 8th grade education?  What proportion had more than
*   4 years of college?  What was the birth year of the person with
*   only a 2nd grade education?
*
*   (Hint: For the last question, sort the data.)

* Problem 2
*----------
* Draw a bar chart of education (grade).  Make sure the bin (bar)
*    widths are 1 grade wide.  Label the y-axis with percents.
*    Save the graph for later.

* Problem 3
*----------
* This data set has no "wage" variable, but it does have ln(wage).
*   Create a wage variable.  What is the average wage among these
*   women?  The minimum?  How much education does the woman with
*   the largest income have?

*   (Hint:  Use "generate."  The opposite of ln() is exp(). )

* Problem 4
*----------
* Draw a scatterplot of education and wage.  Save it.

* Problem 5
*----------
* Close Stata, saving your data set for later (save it in U:\).
*    Combine your logged results and your two graphs in Word.
*    Save them as a .pdf file.
