Which is the best graph for the data?

March31

So, growing mathematicians, how would you best graph the data in the previous post? We have 867 for Australia and 57 for France. Can these be fitted easily onto a y-axis (vertically)? Is a column graph (with gaps) better than a histogram (with no gaps)? Or would you use a pie or line graph? As […]

The IFS took a large group of children born in April 1970, […]
