Bar Graphs and Climate
Bar graphs are useful tools when comparing data values. For example, the bar graph below compares the average yearly rainfall in various climate zones. To create a bar graph, first create an empty box. Then begin on the x-axis by labeling the bar positions with the names of the items you want to compare, in this case the climate zones. Label the y-axis with numbers in the increments of measurement, in this case 0 to 250 cm. Finally, draw the bars on your chart to represent data.
PRACTICE
Answer the following questions based on the information in the graph above.
1. On average, which climate zone receives the most rainfall every year? About how much rain does it get?
2. On average, which climate zone receives the least rainfall every year? About how much rain does it get?

3. On average, which two climate zones receive the same amount of rain annually? Are these two zones the ones you would expect to have equal amounts of precipitation? Explain your answer.
4. The table below shows the average annual rainfall for India—the country as
a whole and particular cities and regions. Create a bar graph using the data shown.
India’s Average Annual Rainfall
Region / Rainfall (in.)India / 49
Western Ghats / 125
Khasi Hills / 430
