Question

The main difference between a frequency polygon and a histogram is that a frequency polygon uses lines to connect the midpoint of each interval, while a histogram uses bars to represent the frequency. A frequency polygon can be drawn for the same range of data values as a histogram and can be used for both ordinal and interval data. Frequencies still appear on the y-axis in both types of graphs.
