Yatay eksene (x-ekseni) sınıf orta noktalarını, dikey eksene (y-ekseni) ise frekansları yerleştirin.
: ( x_i = \frac\textLower limit + \textUpper limit2 ) frekans poligonu
Verinizi anlamlı aralıklara (bin) bölün. Örneğin; 0-10, 10-20, 20-30 gibi.

: Uses relative frequencies (proportions or percentages) instead of raw frequencies, enabling comparisons between datasets of different sizes.
Frequency Polygon (Frekans Poligonu). What is a Frequency Polygon? A frequency polygon is a line graph used to represent the distribution of data. Unlike a bar-based histogram, it uses straight line segments to connect points plotted above the midpoints of class intervals. Key Advantage: It is particularly useful for comparing two or more sets of data on the same axes without the visual clutter of overlapping bars. Visual Shape: It often resembles a "mountain range" or a "shark fin," showing where data peaks and how it trails off. How to Construct a Frequency Polygon You can create a frequency polygon either by using an existing histogram or starting from a frequency distribution table. Step 1: Find the Midpoints (Class Marks) For each class interval, calculate the exact middle value. Formula: Lower Limit Örneğin; 0-10, 10-20, 20-30 gibi
The frequency polygon is a simple yet powerful graphical tool used in descriptive statistics to visualize the distribution of a continuous or discrete dataset. By connecting midpoints of class intervals with straight lines, it provides a smooth, polygonal shape that reveals patterns such as central tendency, dispersion, skewness, and modality. This paper explains how to construct a frequency polygon, contrasts it with histograms, discusses relative frequency polygons, and demonstrates its use in comparing multiple distributions.
