Data Representation and Bar Graphs

The video tutorial introduces data representation, focusing on bar graphs. It explains how data can be represented using pictures, symbols, graphs, or numbers. The tutorial details the components of a bar graph, including the title, labels, and scale. Two examples are provided: one about flowers collected and another about fruits eaten by Max the mouse. The video demonstrates how to interpret bar graphs to extract meaningful information.

What is the primary purpose of data representation?

• To represent information in a clear and understandable way

• To confuse the reader

• To make data collection difficult

Which of the following is NOT a method of data representation?

• Static and dynamic

What does the title of a bar graph indicate?

• The subject of the data represented

• The type of graph

• The color of the bars

• Six

• Seven

• Four

What does the scale on a bar graph represent?

In the fruits eaten by Max example, how many apples did Max eat?

• Three

• Two

• Four

• Five

What can be determined from the bar graph about the fruits eaten by Max?
