What is a frequency curve?
Understand the Problem
The question is asking for a definition and explanation of a frequency curve, which pertains to statistical concepts and data representation.
Answer
A frequency curve relates the magnitude of a variable to its frequency of occurrence, showing a smoothed version of a data distribution.
A frequency curve is a graphical representation of the distribution of a set of data that relates the magnitude of a variable to its frequency of occurrence.
Answer for screen readers
A frequency curve is a graphical representation of the distribution of a set of data that relates the magnitude of a variable to its frequency of occurrence.
More Information
Frequency curves are used in many fields, including hydrology, to depict how often different magnitudes of a variable occur. They are helpful for visualizing and analyzing the distribution patterns of large datasets.
Tips
A common mistake is confusing frequency curves with histograms. Frequency curves are smoother and continuous, while histograms use bars.
