A Frequency Curve represents a smooth curve derived from a histogram for a continuous distribution with a large number of data points. It showcases the frequency distribution in a more visual and simplified way. On the other hand, a Frequency Polygon is a line graph showing class frequencies plotted against class midpoint, created by linking the midpoints of the histogram's rectangles. Histograms, meanwhile, offer a graphical representation of data distribution through adjacent rectangles, each representing a data category. These tools are instrumental in analyzing and interpreting data in statistical geography.

Frequency curve • A Frequency Curve is a smooth curve which corresponds to the limiting case of a histogram computed for a frequency distribution of a continuous distribution as the number of data points becomes very large.
Frequency Polygon • A frequency polygon is a line graph of class frequency plotted against class midpoint. It can be obtained by joining the midpoints of the tops of the rectangles in the histogram
Histogram • In statistics, a histogram is a graphical representation of the distribution of data. The histogram is represented by a set of rectangles, adjacent to each other, where each bar represent a kind of data.
