5. Spreadsheet Basics
• Excel spreadsheets organize information (text and numbers) by rows and columns
5
This is a row
Rows are represented by
numbers along the side of
the sheet.
This is a column
Columns are represented by
letters across the top of the
sheet.
A cell is the intersection between
a column and a row
Each cell is named for the
column letter and row number
that intersect to make it.

6. Multiple Sheets
• You start with one Sheet by default when you create a new workbook.
• You can have many sheets in a workbook. New sheets can be added and removed.
Sheets can be named to making it easier to work with data sets.

7. Formulas & Cell References
• A formula in Excel is used to do mathematical calculations. Formulas always start with the
equal sign = typed in the cell, followed by your calculation.
7
• To create a formula
o Select a cell
o Type the equal sign (=)
o Select a cell or type value
o Enter an arithmetic operator
o Select another cell or type value
o Press enter

8. Formulas & Cell References
8
• Cells in Excel have unique references,
which is its location
• References are used in formulas to do
calculations, and the fill function can be
used to continue formulas sidewards,
downwards and upwards

9. Functions
9
• Excel has many premade formulas, called functions
• Functions are typed by = and the functions name
• For example =SUM(A1:A5) is the sum up of cells from A1 to A5
• The range is always inside of parentheses

10. Functions: SUM
• The SUM function is a premade function in Excel, which adds numbers in a range
10

11. Functions: MIN, MAX, AVERAGE
• The MIN function is a premade function in Excel, which finds the lowest number in a range
• The MAX function finds the highest number in a range
• The AVERAGE function is a premade function in Excel, which calculates the average
(arithmetic mean)
11

12. Functions: COUNTIF

15. Data Analysis: Sort
• Ranges can be sorted using the Sort Ascending and Sort Descending commands
15

16. Data Analysis: Filter
• Filters can be applied to sort and hide data. It makes data analysis easier.
16

17. Charts: Column Chart
• Charts are visual representations of data used to make it more understandable
• Column charts show the data as vertical bars
• Column charts are suited for representing values of qualitative (categorical) data
17

18. Charts: Line Chart
• Charts are visual representations of data used to make it more understandable
• Line charts show the data as a continuous line, which are typically used for showing trends
18

19. Charts: Pie Chart
• Charts are visual representations of data used to make it more understandable
• Pie charts arrange the data as slices in a circle
• Pie charts show the contribution of each category to the total
