Mathematics - Term 2 - Week 6

Data handling is the process of collecting, organizing, and interpreting information. In our daily lives, we encounter data everywhere, from the number of students in our class to the types of fruits we like. Today, we will learn how to represent this information visually using charts and graphs, making it easier to understand and analyze.

Let's say we asked our classmates about their favorite fruits. The results were: 5 students chose apples, 3 chose bananas, and 2 chose oranges. We can represent this data in a bar chart. First, we draw a vertical line for the fruits and a horizontal line for the number of votes. We then draw bars for each fruit according to the number of votes. This visual representation helps us see which fruit is the most popular at a glance.

Now, let's conduct a survey in class. Ask each student their favorite color. As they respond, write down the results on the board. After collecting the data, we will create a bar chart together. Each student will help draw the bars for their favorite color. This will reinforce how we can visualize data and see trends in our class preferences.

Complete the worksheet provided. You will collect data from your family members about their favorite pets. Record the number of votes for each pet type and then create a bar chart to represent your findings. Make sure to label your chart clearly and write a few sentences interpreting the data you collected.
