Types Of Graphs
Bar graph - a diagram in which the numerical values of variables are represented by the height or length of lines or rectangles of equal width.
Bar graphs are used to compare things between different groups or to track changes over time. However, when trying to measure change over time, bar graphs are best when the changes are larger.

Line Graph - A graph that uses points connected by lines to show how something changes in value (as time goes by, or as something else happens).
Line graphs are used to track changes over short and long periods of time. When smaller changes exist, line graphs are better to use than bar graphs. Line graphs can also be used to compare changes over the same period of time for more than one group.

Pie Graphs - a type of graph in which a circle is divided into sectors that each represent a proportion of the whole.
Pie charts are best to use when you are trying to compare parts of a whole. They do not show changes over time.

Scatter Plot - a graph in which the values of two variables are plotted along two axes, the pattern of the resulting points revealing any correlation present.
X-Y plots are used to determine relationships between the two different things. The x-axis is used to measure one event (or variable) and the y-axis is used to measure the other. If both variables increase at the same time, they have a positive relationship. If one variable decreases while the other increases, they have a negative relationship. Sometimes the variables don't follow any pattern and have no relationship.

Stem Leaf Plot - is a method of organizing numerical data in order of place value. The 'ones digit' and the 'tens digit and greater' of each data item is separated as leaves and stems respectively.
Showing the frequency with which certain classes of values occur. You could make a frequency distribution table or a histogram for the values,
