Learning Objectives

Indicator: B6.4.1.2.3 - Design and administer a questionnaire for collecting data to answer given question(s), record the data, analyse and graph the results to solve problems

By the end of the lesson, learners can:

Read and interpret a frequency table made from tally marks to identify the most and least frequent responses.
Construct a bar graph or line graph from a frequency table, including the title, axes labels and appropriate intervals.
Write at least two accurate statements or conclusions based on the graph they have drawn.
Use the results from a class survey to make a practical decision, such as choosing an item to buy, and justify that decision with evidence from the data.
Work in a small group to take a simple survey, record responses using tallies, organize the data into a frequency table, and present the findings as a graph.

Exemplars (from the NaCCA curriculum)

E.g. 1. Guide learners (in each small group) to use tallies and count the results obtained in the organized data table (see P6.5.2.2.3 above) to do a frequency table for each question.
E.g. 2. Ask learners to study the results in the frequency tables to draw bar or line graphs and write their conclusion.
E.g. 3. Ask learners to identify questions for a survey, do a question form and collect real data, organize the data obtained into frequency tables and graph it using bar or line graphs and the results to solve problems. They may do surveys on the following situations or issues: (a) The type of drinks to buy for a class party. (b) The make of sport shoes to buy for all P6 students. (c) The make of school bag to buy for all P6 students.
