A method of converting a frequency distribution of scores into increasing percentages as a function of the percentage of scores counted. A bar graph is often generated by placing the class interval scores along the x-axis and the cumulative percentages along the y-axis.

Frequency Polygon

A method of converting a frequency distribution of scores into a line graph. After combining scores by class interval, the class intervals are placed along the x-axis and the frequency of scores along the y-axis.

Positively Skewed Curve
