  2. Understanding of data organization
  3. Keyboard input (text editing)

What resources do you need

  1. Computer lab with projection equipment
  2. Student generated data sets
  3. Secondary data sets
  4. Handout for LibreOffice Calc
  5. Handout for LibreOffice Writer

What digital skills will you learn

  1. Working with spreadsheets
  2. Drawing plots and graphs

Description of activity with detailed steps

There are two parts of this activity. The first part is to get familiar with entering data in a spreadsheet. The second part is to learn how to analyse data from a spreadsheet, using secondary data sets.

Teacher led activity

Getting familiar with spreadsheet

  1. Your teacher will demonstrate input of data with spreadsheet
  2. Discuss with your teacher what meaningful measures of data can be calculated
  3. Your teacher will show you the following in a spreadsheet:
    1. Opening LibreOffice Calc and demonstrating how to create a new spreadsheet
    2. Entering data in a spreadsheet - typing in Telugu and English
    3. Sorting (alphabetically or numerically) the data
    4. Simple formatting in a spreadsheet - coloring of cells, making bold, cell borders
    5. Entering simple formulae in a spreadsheet to calculate data; some of the formula to be calculated include total, percentage, minimum, maximum
    6. Drawing charts - bar graphs and pie charts - in a spreadsheet
    7. Copying the table of data entered and inserting into a text document
    8. Inserting the graphs and charts entered into a text document
  4. Your teacher will plot different graphs and discuss how different kinds of graphs can be meaningful. Look at the graphs shown here and determine the advantage of each.
  5. Your teacher will also discuss with you what is the difference between the data set in the first and second example.

Student activities

Tabulating data from a pictograph:

Look at the following data sets captured and tabulate in a spreadsheet. Plot the graph that will make meaning to the data.

Entering given numeric data in a spreadsheet:

Look at the following data sets captured and tabulate in a spreadsheet. Plot the graph that will make meaning to the data. It could be a bar chart or a pie chart. You can see that spreadsheet offers many other types of charts. You should explore these charts for your given table of data and try to understand what they say.

Tabulating collected data from previous activity on organizing data

In the previous activity on organizing data you had collected the data on various kinds of projects. You had also created a concept map and a text document describing your data collection and processing. As a part of this unit, you should enter the data you collected in a spreadsheet, sort, format and also calculate some simple measures of data. You should also add a pictorial or graphical representation of the data.

In the previous activity on organizing data you had created a text document with concept map and a written description. You can add the spreadsheet data into your document along with the charts.

Portfolio

  1. You will add to your folder in this activity a new data format called spreadsheets. The spreadsheets you will create will be your digital portfolio.
  2. Cumulative text document with spreadsheet and chart(s) inserted.
