Data are often presented in tables, with information organized in rows and columns. This exercise will give you the basic concepts of reading a table to find a piece of information.
You need to get familiar with the bar graphs and understand some concepts in order to interpret it the right way
You can better understand the bar graphs through a real-life example.
A pictograph is like a bar graph, but the bars are made from pictures or symbols. A key tells the meaning (or value) of each symbol.
In a circle graph, regions called sectors are used to show what part of the whole each quantity represents.
A line graph, is used to show how quantities change with time. From such a graph, we can determine when a quantity is increasing and when it is decreasing
