Learning Objectives
Indicator: B7.4.1.1.3 - Organise and present data from a survey into a table and/or chart, and analyse it to solve and/or pose problems.
By the end of the lesson, learners can:
- Organise raw data from a survey into a frequency table using tallies, with correct tally marks and frequencies.
- Present organised data in an appropriate chart, specifically a bar graph or pie chart, with accurate labelling.
- Analyse a frequency table or chart by writing at least two valid conclusions about the data.
- Pose at least one relevant question that can be answered using the organised data.
- Select and justify the appropriate chart type (bar graph or pie chart) for a given set of data.

Draw a pie chart to illustrate the data in the frequency table (i.e. in E.g. 1 above). iii. Write your conclusion about the number of people living in the households and/or pose questions on the pie chart. E.g. 3. Draw a graph or chart for data organised in a frequency table and use it to answer and/or pose questions. For instance, i. The table below shows how Fakor spends his day. Complete the blanks in the table with information on how you spend your day. Draw a double bar graph to compare how you spend your day with Fakor.
