Signing the AIPA Forms
 AIPA – Academic Integrity Policy
   Acknowledgement form

 Basically says you are aware of the academic
   integrity policy and its penalties.

 You must sign this form to receive credit for this

Attendance System
 The attendance system uses MasterID, if you haven’t
   activated your MasterID account yet please do so
   immediately. http://masterid.wvu.edu

 Starting next week we will use the web based attendance
   system. If you visit http://cs101.wvu.edu and look to
   the left under Student Tools you will find the link for
   Record Attendance.

 Record your attendance at most 5 minutes before class
   starts, or after class starts.
Submitting an assignment
 All homework assignments and tests will be submitted using the
     web tool. To submit an assignment visit http://cs101.wvu.edu
     and look to the left under Student Tools you will see a link for
     Submit Assignments.
 When you submit an assignment make sure you enter your First
     Name and Last Name and specified the correct section and
     project. If for some reason you select the wrong section or
     project, just resubmit it but let me know by email. Also, if you
     made changes to your assignment and want to submit a new
     version you can do that as well but again let me know via email.
 If the assignment doesn’t submit properly, make sure the file you
     are trying to submit is not open. We will do a demo of the
     submission system next week.
MIX and its issues
 If I don’t respond to your email in a day it means I
    didn’t get it, Groupwise sometimes flags MIX
    accounts as spam. Resend the email from an
    alternate account or talk to me before/after

 If you need a refresher on how to use MIX to send
    files, stop by Open Lab on Friday between 4-
    6PM. Remember MIX is picky with file sizes.

Critical Thinking
   – All Homework Assignments and Tests will
     have a section called Critical Thinking or
     Analysis Questions.

   – Typically 5 questions (you pick your favorite 4)
     pertaining to the assignment or common
     knowledge questions.

   – Yes and No are not good answers, a few
     moments searching on the web can get you a
     more accurate answer.
Sample Critical Thinking questions
    – Automobile accident rates went up in 1995.
      What could cause the accident rates to
      increase suddenly?

 What do each of those pictures have in common?


Using Search Engines
 You might find it useful to search on the web for
   answers to some of the critical thinking
      • Plan your searches
      • Be specific
      • Narrow searches using multiple keywords
      • Use initial results to tweak your search

Common Search Engines


 There are more, but Google and Yahoo are the
   preferred choice.

Search tips
 • cars is a bad search term if you are trying to find
   a Honda Civic, instead searching “Honda Civic”
   will give better results. If you place a search
   item in quotes, the search engine will search for
   the exact phrase.
 • If you searched with just Honda Civic without
   quotes, what would it return?
 • If you are having trouble finding results try using
   synonyms, for example use vehicle instead of
   car to search for a car.

Tweaking Searches
 • Negative terms
   – Virus –computer will find pages that mention
     the word virus but not the word computer.
 • AND and OR queries
   – Most search engines automatically insert the
     word AND between phrases (which is why
     quotation marks are useful) so there is no
     need to type it in the search engine. OR is
     useful for searching for more than one term,
     such as West Virginia University OR WVU.

Better searching tips
 • Google ignores common terms such as where and
   how, as well as single digits and letters.
 • It is not case sensitive. Typing aNoThEr pHrAse will
   return the same results as another phrase.
 • To search for Roman numerals or a common word,
   either use quotations or the + sign. “World War I” and
   World War +I will return about the same results.
 • Use the site command
    – classes site:wvu.edu will return pages that
       reference classes, but only the sites that are on the
       WVU server.

CS101 and search resources
 • Microsoft Office has a fairly good Help system if
   you get stuck when working on something
 • Search for specific items on Google, for
   example: “Microsoft Excel” and “insert chart”
   will give you pages that talk about how to insert
   charts in Excel
 • For some questions searching Wikipedia might
   give a better answer, but be cautious to ensure
   the sources are valid and not opinionated

 • www.wikipedia.com is a free user edited online
 • Information is current and up to date
 • But… what makes Wikipedia bad?
 • If I made a page stating the sun rises in the west
   and stored it on Wikipedia, would that make it a

Evaluating Sources
 • Ask yourself some questions
   – What can the URL tell you?
   – Who wrote the page? Is he, she, or the authoring institution
     a qualified authority?
   – Is it dated? Current, timely?
   – Is the information cited authentic?
   – Does the page have overall integrity and reliability as a
   – What's the bias?
   – Could the page or site be ironic, like a satire or a spoof?
   – If you have questions or reservations, how can you satisfy
When you need quality information
 • Search engines like Google are totally unfiltered.
 • Wikipedia is user edited, information is biased
   or opinionated
 • They work by scouring the web and presenting
   you with whatever the find - without regard to
   the veracity of the information. Google has no
   editorial filter.
 • In cases like this you might need to hunt
   through library databases and so forth.

Math 101
 Understanding number types:
 Integer: An integer is a natural number that can hold a value between -32,768
    and 32,767. Examples of such ranges are the number of pages of a book.
 Long Integer: A long integer is a natural number whose value is between
    –2,147,483,648 and 2,147,483,642. Examples are the population of a city, the
    distance between places of different countries, the number of words of a
 Single: A single is a decimal number whose value can range from –3.402823e38
    and –1.401298e-45 if the number is negative, or from 1.401298e-45 and
    3.402823e38 if the number is positive.
 Double: While the Single data type can allow large numbers, it offers less
    precision. This is used for numbers that range from 1.79769313486231e308
    to –4.94065645841247e–324 if the number is negative or from
    1.79769313486231E308 to 4.94065645841247E–324 if the number is positive.

Data Collection
 • One big issue with data analysis is trying to figure out
   whether we need more data or less data

 • How often should one collect data?
    – Gas prices – do we collect daily, weekly, monthly
    – Stock prices – do we collect daily, weekly, monthly
    – Population – do we collect daily, weekly, monthly

 • Gathering data too frequently can lead to excessive
   data (slows down resources) but not collecting data
   frequently enough can lead to poor results
 Each Lesson consists of multiple chapters

 Each Chapter has multiple questions

 Each question has multiple steps

   Excel shortcuts, you might find some of them

First Spreadsheet
 • Open up Excel
 • Create a file called
   – Adding the date after the spreadsheet can
     sometimes be useful if you have multiple variants of
     the same spreadsheet. You don’t need to add the
     .xlsx as Excel adds it in for you automatically
 • Where you save your spreadsheet doesn’t
   matter, but you should remember where it’s
   saved so you can locate it later
Renaming sheets, tab color
 • By default you get three sheets – Sheet1, Sheet2,
 • Name them to what is relevant to the task, don’t ever
   leave them at the default names.
 • To delete a sheet – right click and select delete
 • To insert a sheet – right click and select insert or click
   the insert sheet icon to the right of the last sheet
 • To change Tab color – right click and select Tab Color.
   This can be very helpful when trying to locate a sheet
   in a workbook with multiple sheets.
