2 de abr. de 2023 · Frequency polygons are analogous to line graphs, and just as line graphs make continuous data visually easy to interpret, so too do frequency polygons. To construct a frequency polygon, first examine the data and decide on the number of intervals, or class intervals, to use on the x-axis and y-axis.

The vertical axis is labeled either frequency or relative frequency (or percent frequency or probability). The graph will have the same shape with either label. The histogram (like the stemplot) can give you the shape of the data, the center, and the spread of the data.

Histograms, Frequency Polygons, and Time Series Graphs | Introduction to Statistics. Learning Outcomes. Display data graphically and interpret graphs: stemplots, histograms, and box plots. Recognize, describe, and calculate the measures of location of data: quartiles and percentiles.
A histogram is a visual display of a frequency chart. It consists of contiguous, vertical boxes with both a horizontal axis and a vertical axis. The horizontal axis is labeled with the classes or categories from the frequency chart. The vertical axis is labeled either frequency or relative frequency (or
While a histogram is a graph with rectangular bars without spaces, a frequency polygon graph is a line graph that represents cumulative frequency distribution data. Frequency polygons look like the image below: Steps to Construct Frequency Polygons. The curve in a frequency polygon is drawn on an x-axis and y-axis.
