    -Specify whether each variable
    is quantitative or qualitative? If they are quantitative, categorical or
    continuous?

    -Graph the data using
    appropriate figure.  Don’t forget the
    label for each axis and the caption.

    (Animal 1 was 10cm tall and
    weighed 5grams, Animal 2 was 25cm tall and weighed 13grams, Animal 3 was 50sm
