The document describes the steps to create a frequency histogram polygon from a frequency table. It involves plotting the scores on the horizontal axis with equal intervals, plotting the frequencies on the vertical axis starting from 0 and increasing by the same interval up to the maximum frequency, placing dots in the middle of each histogram bar, and joining the dots with straight lines to form the polygon.
