1. What is a spreadsheet?
A spreadsheet is a computer program used
to store and manage data in the cells which
are represented in the form of rows and
columns.
The data is stored as a record in the
spreadsheet and can be manipulated.
2. What is Microsoft Excel?
It is a spreadsheet program developed by
Microsoft. Excel organizes data in columns and
rows and allows you to do mathematical
functions.
MS Excel is one of the software programs that
helps you make a spreadsheet.
3. A function is a preset formula that helps
perform mathematical, statistical and logical
operations.
Once you are familiar with the function you
want to use, all you have to do is enter an
equal sign (=) in the cell, followed by the
name of the function and the cell range it
applies to.
What is a Function?
5. a FORMULA is an expression that operates on
values in a range of cells. These formulas return
a result, even when it is an error. Excel formulas
enable you to perform calculations such as
addition, subtraction, multiplication, and division.
Example:
=Sum(A1:A7)
=CountIf(C3:C10,”Male”)
What is a Formula?
6. Range - defines one or several cells to count. You put
the range in a formula like you usually do in Excel, e.g.
A1:A20.
Criteria - defines the condition that tells the function
which cells to count. It can be a number, text string, cell
reference or expression. For instance, you can use the
criteria like these: "10", A2, ">=10", "some text".
Range and Criteria
7. Sum Function
The SUM function adds values. You can add individual
values, cell references or ranges or a mix of all three.
MS Excel Functions:
8. SumIf Function
It will sum up cells that meet the given criteria. The
criteria are based on dates, numbers, and text. It
supports logical operators such as (>, <, <>, =)
Formula:
=SUMIF(range, criteria, [sum_range])
MS Excel Functions:
9. Count/CountA Function
The COUNTA function counts cells containing any type
of information, including error values and empty text
("").
If you do not need to count logical values, text, or error
values (in other words, if you want to count only cells
that contain numbers), use the COUNT function.
Formula:
=Count(range)
=CountA(range)
MS Excel Functions:
10. CountIf/CountIfs Function
used for counting cells within a specified range that meet
a certain criterion, or condition.
Formula:
COUNTIF(range, criteria)
If you have two criteria and conditions use the CountIfs
function.
Formula:
=CountIfs(criteria_range1,criteria1,criteria_range2,criteria2)
MS Excel Functions:
12. AverageIf Function
Calculates the average value in a range of cells that
meet the specified criteria.
Formula:
=AVERAGEIF(range,criteria, [average_range])
