Statistics is that branch of mathematics that converts data into some useful information. This transformation requires complex calculations which can easily be done using computers. Attempting these computations manually is sometimes a herculean task for such data. Accordingly, SPSS was created to help researchers in handling large volume of data that they collects.

Creating Graphs
SPSS have strong capabilities of depicting data in a magnificent way. It depicts high quality graphs and charts with highly enhanced and editing tools.Further, choosing the right type of charts and graph according to the data is the key point to consider by the researcher. Moreover, selecting the scale of a diagram should be appropriate for a given situation.

Creating Bar Graphs
A bar graph or charts depicts the magnitude, sizes or the differences at equal intervals of time. It depicts the changes in the value of the dependent variable plotted on Y-axis at discrete intervals of the independent variable on x axis. This means that on x axis of the bar diagram is a discrete variable while the other axis represents a scale for one of continuous variable. Bars can also be created as two dimensional or as percentage components bars in SPSS. Bars are vertical lines where the lengths of the bars are proportional to their numeric values.
