1. Data Analysis Formula and Functions

2. Formula and functions A function is a calculation in a spreadsheet that has or can be memorized. There are many different functions. A function must start with an equal sign = Sum =SUM(E3:P3) Total of all cells…. Average =AVERAGE(A3:A10) Average in a range…. Maximum =MAX(D3:J3) Display largest number…. Minimum =MIN(D3:J3) Display the smallest number…. Mode =MODE(A3:A15) Display mode (Most frequent…)…. Median =MEDIAN(B2:W2) Displays the Median number (Middle)….

3. INTEGER An integer is a positive or negative whole number or zero. Excel uses the INT function to only give the whole number part of a number. It is important to note that it simply chops off the decimal part of a number just to leave the integer part. =INT(12,99) will return the integer 12 =INT(0.31022) will return the integer 0

4. IF The IF function is called a logical function because it makes the decision to do one of two things based on the value it is testing. The IF function is very useful because you can use it to test a condition, and then choose between two actions based on whether the condition is true or false. IF makes use of something called relational operators

5. RELATIONAL OPERATORS SymbolMeaningExamples =Equals5+5=10 >Greater than5*3 > 2*3 <Less than-6 < -1 Not equal to“Red” “White” < =Less than or equal to“Adam” < = “Eve” > =Greater than or equal to400 > = 200

6. NESTED FUNCTIONS A nested function is a function which is inside another function.
