Comparing Data on a Double Column Graph: Electronics

Overview:

A data interpretation activity where students analyse a double column graph showing sales data from two electronics stores, Pete’s Electrics and Sam’s Superstore, to answer comparison and calculation questions. Designed for students in the middle and upper years.

Learning Objectives:

• Interpret data from a double column graph accurately.
• Compare data sets to identify differences and trends.
• Perform calculations using data to answer real-world questions.

How the Activity Works:

Students are presented with a double column graph displaying sales figures for various electronics products at two stores. They answer questions such as identifying which store sold the most game consoles and TVs, determining how many laptops Sam’s Superstore sold, and calculating the difference in sales for specific products. Students also analyse which store sold the most products overall and calculate the total revenue from tablet sales based on the given profit margins for each store. This activity provides a practical and engaging way for students to practise interpreting data, performing calculations, and applying their understanding to real-world scenarios.
