Excel Note
 In excel, one square is called “cell”
 A1 is called as “name box”
 The long horizonal bar is “function bar”
 When you select some areas, the areas are called “range”
 Cell referencing – use the function/formula of the latest row. It
doesn’t copy exact like the before one, it just uses the format of the
cell.
 if you want to add or subtract the value, write =(equal) in the answer
box then select value 1 and add – or + then select , value 2 lastly click
enter.
 “count” only count number, it doesn’t count text, code or character.

Cell Referencing
-It is a method of referring to a cell or a group of cells in a spreadsheet
by using their cell address.
Excel Note
Relative Cell Referencing
-It is a feature of spreadsheet cell reference changes automatically
when a formula is copied to another cell commonly used when the
same calculation is needed for different rows and column.
Absolute Cell Referencing
-Absolute cell referencing is a type of cell reference that does not
change when a formula is copied to another cell. It uses the dollar sign
($) before the column letter and row number. It is used when a formula
must always refer to the same fixed cell.
Average if
-start with equal (=) then average if
e.g.
=averageif(C2:C8,B2:B8,”A”,C2:C8,”>=50”
)
-cells contain numbers, not text
-use (:) for a range
Lookup () – lookup search for a value in one row or one column and
returns a corresponding value from another row or column. It works
only sorted data (ascending order). Less flexible.
-V lookup () -> Vertical lookup -search vertically and returns data from
another column to the right. easy to understand. Very commonly used.
-X lookup () -> it can search left, right, up, or down. Doesn’t require
sorted data. More accurate and easy.
-H lookup () -> Horizontal lookup -search horizontally and returns data
from a row below useful for searching horizontal data
Excel Note
V lookup function
-to find the data in sheet
-has two types (vertical lookup and horizontal lookup)
Steps – write “=vlookup” then select data you want to find, and select
the whole table (doesn’t include the field names), then the row number
you want to find (e.g. 2), then choose true or false
