How many books did 6th graders at Taylor Middle School read this summer?
Reading a Histogram• A histogram looks like a bar graph, except that answers are
grouped together. On the x-axis at the bottom you will see the intervals. In this graph about the number of coins being brought for a coin drive, there were 3 students who brought between 0 and 4 coins. They might have brought 0 coins, or maybe they all brought 4, but we can’t tell. 8 students brought between 5 coins and 9 coins, Again, we can’t tell exactly how many each person brought, just how many brought between 5 and 9 coins.
