  • use formulas and functions such as SUM, AVERAGE, MIN, MAX, and MEDIAN
  • edit and format worksheets
  • create charts
Create a worksheet named Student Scores with the following data:


Tasks

1. Enter the data into the worksheet.
2. Add a new column called Average.
3. Use a formula to calculate the average score for each student.
4. At the bottom, calculate:
  • minimum average
  • maximum average
  • median average
  • overall class average
5. Format the table neatly 
  • Using your own creativity - Interesting and yet professional
6. Create a chart that is relevant and explain why you use this type of chart

Creating a Chart

What is a Chart?
A chart is a visual representation of data.

Common Types of Charts
  1. Column chart: compares values
  2. Bar chart: compares categories
  3. Pie chart: shows proportions
  4. Line chart: shows trends over time
Steps to Create a Chart
  1. Select the data.
  2. Click Insert.
  3. Choose a chart type.
  4. Add a chart title.
  5. Edit labels if needed.
Example


Questions
  1. What is the best Chart for This Data
  2. Which item has the highest sales

Editing and formatting a worksheet

Editing a Worksheet
Editing means changing the worksheet content or layout.

Common Editing Actions
  1. insert rows or columns
  2. delete rows or columns
  3. copy and paste data
  4. cut and move data
  5. rename sheet tabs
Formatting a Worksheet
Formatting makes the worksheet easier to read and more attractive.

Common Formatting Actions
  1. bold text
  2. change font size
  3. change text color
  4. fill cell color
  5. add borders
  6. center align text
  7. format numbers as currency, percentage, or date
Example of Good Formatting

For a sales table:
  1. make headings bold
  2. add borders to the table
  3. highlight headings with color
  4. format prices as currency
  5. adjust column width
Exercise 5: Editing and Formatting
Use the table from previous Exercise

Task
  1. Make the headings bold.
  2. Change the heading row color.
  3. Add borders to all cells.
  4. Format the Price and Total columns as currency.
  5. Center-align the headings.
  6. Rename the sheet tab as Sales Data.

Using formulas and functions (min, max, median, average, sum)

What is a Formula?
A formula is an equation used to calculate values in a spreadsheet. Every formula starts with =.

Example:
=B2*C2

What is a Function?
A function is a built-in formula.

Common Functions
SUM = adds values
AVERAGE = finds the mean
MIN = finds the smallest value
MAX = finds the largest value
MEDIAN = finds the middle value

Example Data

Enter this in cells A1:B6:


How to Use Functions

Assume marks are in cells B2:B6.
  1. Total marks: =SUM(B2:B6)
  2. Average marks: =AVERAGE(B2:B6)
  3. Minimum marks: =MIN(B2:B6)
  4. Maximum marks: =MAX(B2:B6)
  5. Median marks: =MEDIAN(B2:B6)
Exercise 3: Functions Practice

Using the marks table above, calculate:
  1. Total marks
  2. Average marks
  3. Highest marks
  4. Lowest marks
  5. Median marks
Exercise 4: Formula Practice

Enter this table in cells A1:C5:


Task
  1. In column D, create a heading called Total.
  2. In cell D2, enter a formula to calculate Quantity × Price.
  3. Copy the formula down to D5.
  4. In D6, calculate the grand total using SUM.

Entering and Correcting Data

How to Enter Data
  1. Click on a cell.
  2. Type the data.
  3. Press Enter.
Types of Data
  1. Text: names, subjects, items
  2. Numbers: marks, prices, quantities
  3. Dates: 12/4/2026
  4. Formulas: =A1+B1
How to Correct Data

Method 1: Double-click the cell
Double-click the cell and edit the content.

Method 2: Use the formula bar
Click the cell, then edit the content in the formula bar.

Method 3: Replace the data
Click the cell, type new data, and press Enter.

Exercise 2: Enter and Correct Data

Enter the following table into a worksheet starting from cell A1:


Task

  1. Change the quantity of Book from 5 to 7.
  2. Change the price of Ruler from 2.00 to 2.50.
  3. Correct Eraser to Pencil.


Spreadsheet Interface What is a Spreadsheet?

 What is a Spreadsheet?
A spreadsheet is a computer program used to organize data in rows and columns. It helps users calculate values, present information neatly, and create charts.

Examples of spreadsheet software:
  • Microsoft Excel
  • Google Sheets
  • LibreOffice Calc
Spreadsheets are useful for students, teachers, businesses, and anyone who works with numbers or lists.

Main Parts of the Interface

a) Workbook
A workbook is the whole spreadsheet file.

b) Worksheet
A worksheet is one page inside the workbook.

c) Rows
Rows run horizontally and are numbered: 1, 2, 3, and so on.

d) Columns
Columns run vertically and are labeled: A, B, C, and so on.

e) Cell
A cell is the box where a row and column meet, such as A1 or B3.

Example:
  • A1 = Column A, Row 1
  • C5 = Column C, Row 5
f) Formula Bar
This shows the content or formula in the selected cell.

g) Sheet Tabs
These are found at the bottom and allow you to move between worksheets.

h) Ribbon / Toolbar
This contains commands such as save, format, insert chart, and functions.

Exercise 1: Identify the Interface (Explain to the person next to you)

Open a spreadsheet application and identify:
  1. Workbook
  2. Worksheet
  3. Row
  4. Column
  5. Cell A1
  6. Formula bar
  7. Sheet tabs
  8. Toolbar or ribbon
  9. Task
Write down the cell reference for:
  1. the cell in column C and row 5
  2. the cell in column A and row 10
  3. the cell in column E and row 2
Conclusion
Spreadsheets are very useful for organizing information, doing calculations, and presenting data clearly. By learning the interface, entering data, using formulas and functions, formatting worksheets, and creating charts, students can perform many basic tasks more easily and accurately.
