Description of activity with detailed steps

Teacher led activity

  1. Your teacher will use the data given here to discuss how data elements can be identified for any set of data. Each data element will have a value associated with it and the data can be organized along those values.
  2. For example, the first photograph here is of spices - data elements here can include things like colour, smell, size, texture, shape, taste, grown in Telangana, etc. Each one of these elements will also have a value associated - for example, smell can have values like "mild", "strong", "no smell".
  3. For the second picture, the map represents the population by language spoken. The data elements for each language can be, number of people, region of the county, comparable language in terms of number of people. This map is an example of an infographic.
  4. Once data elements have been identified and tabulated, it is possible to make further analysis by plotting in charts or graphs.

Student activities

Data collection and organizing Now you will create your own data sets based on things around you. You will work in groups with your friends. In this section we will focus on creating data sets in the class. The following activities can be taken up by different sets of students. For all these data sets, make pictographs when possible and also represent in a table form (You can also create table in your text document, and insert the data into the rows and columns).

  1. Data is about us: Data is about us, around us. To see how, collect the following information about your class:
    1. Make a list of the kinds of foods eaten in the class over a week - these should be in some categories like sambar, rice, brinjal etc. And tabulate this as pictograph and with numbers. Also list the food groups covered in the diet in each day.
