IMPORTANT ANNOUNCEMENTS !!!

• Homework #1 has been posted and due by 2/6/2015.

• Homework #2 will be also posted by Friday.

• All the MyITLab/ HW’s are due by 11:59 pm on the due date specified.

ATTENDANCE

• Register your attendance only after 09:25 AM Section 3 and 10:25 AM Section 5.

• As few students have recorded their afternoon before 09:25 AM/ 10:25 AM and it will display in my records as ‘Wrong Time’.

• Even if you arrive early, look at the TIME in the computer and login after 09:25 AM/ 10:25 AM.

MYITLAB

• PRE and POST TEST. Credit is only for the POST TEST.• POST TEST – It is good if you have completed 100%.• But even with 95% completion, that is one question being

unanswered, it should be good.• You must complete at least 190 questions during

semester out of available 215 - 220 questions.• Of course you can gain extra bonus when you answer

more than 190 questions.• Works best in ‘Google Chrome’.

• Submission should be done from the computers in the class and before ending of the class.

• Remember out of 12, you must complete ‘10’ in-class projects.

TILL NOW…

• Cell and Cell addresses• Formulas (start with = sign)• Cell references

– Relative B2– Absolute $B$2

(When we require to make a value constant)– Mixed

Row mixed reference B$2

Column mixed reference $B2

• Workbook/ Formatting/ Print Options/ Importing Data

FUNCTIONS

FUNCTION BASICS

• Function – In excel it is a predefined computation that simplifies creating a formula.

Ex: SUM instead of entering =B1 + B2 + B3 +….

• Excel contains more than 400 functions which are organized into different categories. Date and Time Financial Logical Lookup & Reference Math & Trig Statistical

9

FUNCTION BASICS

• Usually the function name describes the purpose.

Ex: SUM function – Adds up the values.

AVERAGE function – To calculate the average

• Syntax – Starts with an equal = sign

• A function requires arguments which are the values, cell addresses.

• Two ways of inserting functions in excel

INSERTING A FUNCTION

INSERTING A FUNCTION

BASIC MATH AND STAT FUNCTIONS

• SUM - Total amount spent on dining out• AVERAGE - Average amount spent on

iTunes to downloading music• MIN - Lowest time to run a mile this week• MAX - Highest electric bill in a year• COUNT - # of people attend an event• MEDIAN - Same as average

SUM FUNCTION

• Totals the values and displays the result in the cell where we entered the function.

• More efficient when we add values in three or more cells

• =SUM (A2:A14) (No need of space after equal sign)

AVERAGE AND MEDIAN FUNCTION

• Calculates the central tendency i.e., values tend to cluster around a central values.

• The AVERAGE function calculates the arithmetic mean or the average for the range of cells.

• =AVERAGE (A2:A14) (No need of space after equal sign)

• The MEDIAN function finds the mid-point value and more reflective of the data set.

• =MEDIAN (A2:A14)

MIN AND MAX FUNCTION

• Identifies the Low and High Values.

• Manually inspecting a sheet is inefficient especially if data is large.

• =MIN (A2:A14)• =MAX(A2:A14)

COUNT FUNCTION

• Identify the Total Number with COUNT.

• We have three variations:

– COUNT – excludes blank or N/A cells– COUNTBLANK – counts blank cells – COUNTA – excludes only blank cells.

BASIC MATH AND STAT FUNCTIONS

DATE FUNCTIONS

• Today• Now• Date• Day• Edate• Eomonth• Month• Year

DATE FUNCTIONS

• The TODAY function displays the current date.• Excel automatically updates it when you open it.• Doesn’t require arguments, but you need to enter as

=TODAY()

• The NOW function used the computer’s clock to display the date and time.

• =NOW()

• Omitting the parenthesis creates a #NAME? error.

LOGICAL FUNCTIONS

• A lot of work in Excel involves comparing data in different cells.

• Logical functions test the Logic of situation and return a particular result.

A ??? B

LOGICAL FUNCTIONS

• Is value A equal to value B (A=B)• Is A greater than B (A>B)• Is A less than B (A<B)• Is A greater than or equal to B (A>=B)• Is A less than or equal to B (A<=B)• Is A not equal to B (A<>B)

• These are called Logical or Boolean operators because there can only be two possible answers in any given case - TRUE or FALSE.

LOGICAL ‘IF’ FUNCTIONS

• Most common logical function is the IF function.

• The function returns one value when a condition is met (TRUE) or returns another value when condition is not met (FALSE).

• =IF(Logical_Test, Value 1, Value 2)

LOGICAL ‘IF’ FUNCTIONS

NEXT CLASS

• More functions VLOOK UP, PMT etc.

• Range names
