One way is to use the Histogram tool of Excel's Analysis ToolPak. Arrange
the data in column, and also enter "bin" values (7,8,9,10,11) in a column;
then use the tool.

Other ways include a pivot table or worksheet functions like FREQUENCY or
COUNTIF.

You might also want to examine the relationship between height and age using
an XY(Scatter) chart.
