We can collect data for different purposes. As we collect data, we can represent the data by drawing and seeing it by a different perspective. There are different ways how we can draw data for example: picture graph, bar graph, line graphs, etc. In our case, our bar graph will identify how many of us enjoy hobbies without technology.

With the survey that we will conduct today as a class, we will be able to determine how many of us enjoy doing different hobbies that does not include using technology.

We will tally all votes, we will analyze the data and we will now record it by drawing a bar graph.

For the in class activity each group will complete a problem from their book. Each group will complete the same steps as we did as a class and at the end each group will present their bar graph to the class.
