  I assume everyone knows a bit about basic Chemistry.  The variables in the dataset are

  • Location
  • MO = month
  • PH = pH, pH scale -- ((chemistry) p(otential of) H(ydrogen); the logarithm of the reciprocal of hydrogen-ion concentration in gram atoms per liter; provides a measure on a scale from 0 to 14 of the acidity or alkalinity of a solution (where 7 is neutral and greater than 7 is acidic and less than 7 is basic))  See WordNet for the following.
  • K = potassium, K, atomic number 19 -- (a light soft silver-white metallic element of the alkali metal group; oxidizes rapidly in air and reacts violently with water; is abundant in nature in combined forms occurring in sea water and in carnallite and kainite and sylvite)
  • NA = sodium, Na, atomic number 11 -- (a silvery soft waxy metallic element of the alkali metal group; occurs abundantly in natural compounds (especially in salt water); burns with a yellow flame and reacts violently in water; occurs in sea water and in the mineral halite (rock salt))
  • CA = calcium, Ca, atomic number 20 -- (a white metallic element that burns with a brilliant light; the fifth most abundant element in the earth's crust; an important component of most plants and animals)
  • MG = magnesium, Mg, atomic number 12 -- (a light silver-white ductile bivalent metallic element; in pure form it burns with brilliant white flame; occurs naturally only in combination (as in magnesite and dolomite and carnallite and spinel and olivine))
  • CL = chlorine, Cl, atomic number 17 -- (a common nonmetallic element belonging to the halogens; best known as a heavy yellow irritating toxic gas; used to purify water and as a bleaching agent and disinfectant; occurs naturally only as a salt (as in sea water))
  • SI = silicon, Si, atomic number 14 -- (a tetravalent nonmetallic element; next to oxygen it is the most abundant element in the earth's crust; occurs in clay and feldspar and granite and quartz and sand; used as a semiconductor in transistors)
  • SO4 =
  • ALK = A pressure- and temperature-independent property of seawater that determines in part the carbon content of seawater. Carbonate alkalinity is the sum of the concen- tration of bicarbonate plus two times the concentration of the carbonate ions. Total alkalinity is the amount of acid required to bring seawater to a pH at which all dis- solved inorganic carbon becomes freely exchangeable. The alkalinity of the oceans is determined with potentiometric or normal titration techniques that detect and measure the presence of bicarbonate, carbonate, and borate ions.  See this Glossary online.

Week 5:

• It seems that the data files for the problems from Ch. 10 were not on the book disk.  I have posted the file for the blood data set and created a hosp data set.  Both are now posted on the Homework page.  Please finish these problems and submit hw 4 when you are finished.
• Also, note that there as a SAS program on the book disk to create the datasets in the book.
• Dates for Quiz and MT are corrected.  Quiz this week Th May 1 and Midterm 1, Th May 8
• Homework 5 has been posted.
• Handouts for Chapters 11, 12, 13 have been posted.
• Check out SAS Online Doc

Week 4:

• Homework 3 is due this week.
• Homework 4 has been posted.
• Handouts for Chapters 8, 9, 10 have been posted.

Week 3:

• Today we will work on getting Homework 1 and Homework 2 posted to Blackboard.  Below are the instructions from the Blackboard user manual, submitted by Paul Le.
• Handouts for Chapters 5, 6, and 7 have been posted.
• Homework 3 has been posted.

HOWTO Post your homework to Blackboard.  Thank you Paul Le

The following is the overview of "Add File" and "Send File" from the User Manual (for me, the student, it the manual is under Tools). It seems I need to choose "Send File" to send the files to your (instructor's) dropbox. I wasn't sure if you are able to see users' (students'?) drop boxes.

"Add File from the Digital Dropbox"
 

Files are added to the Digital Drop Box from the Add File page. A file is not automatically sent to the Instructor or Leader if it is placed in the Drop Box through the Add File option. Files must be sent through the Send File option.

Files that are added to the Drop Box but not sent will show the date and time posted. Once the file is sent to the Instructor or Leader it will show the date and time submitted.
 

"Send File from the Digital Dropbox"
 

Users can select a file already in the Digital Drop Box to send to the Instructor or Leader. Users may also select a file not in the Digital Drop Box on the Send File page. A file sent to the Instructor or Leader that is not in the User's Drop Box is added to the User's Drop Box when it is sent.

Files that are added to the Drop Box but not sent will show the date and time posted. Once the file is sent to the Instructor or Leader it will show the date and time submitted.

Week 2:

• This week we will talk about reading in different types of data files and how to save different type of datafiles.
• We will also talk about libraries, permanent SAS files, and the us of variable labels.
• Handouts have been posted for this week.  See the Handout link above.
• Homework 2 has been posted.  Due Tuesday April 15.
• To turn in the Homework 1 assignments use the Digital DropBox in Blackboard.  You should turn in one file with your following filename:  Lastname_Firstname_hw1.doc

Week 1:

• This week we will Introduce SAS.
• Handout1 and Handout2 have been posted under the Handout link above.
• Homework 1 has been posted.  Due Tuesday April 15.
• To turn in the Homework 1 assignments use the Digital DropBox in Blackboard.  You should turn in one file with your following filename:  Lastname_Firstname_hw1.doc

Week 0:

• The book for the class is:  Learning SAS by Example, A Programmer's Guide, Ron Cody, SAS Press Series, 2007.  ISBN 978-1-59994-165-3
