Interpreting Double-Bar Graphs
Analyze and display data using Interpreting Double-Bar Graphs in Grade 9 math. Interpret statistical graphs, identify trends, and draw conclusions from data sets.
Key Concepts
Property A double bar graph shows groups of two bars side by side. This allows easier comparison of two related sets of data.
Examples In 2004, Sal and Harry had the same number of shops: 14. The greatest difference was in 2006: Harry had 18 shops and Sal had 11, a difference of $18 11 = 7$. In March, Andre's deposits and withdrawals were equal at 350 dollars.
