What is a frequency curve?
Understand the Problem
The question is asking for an explanation of what a frequency curve is, which likely involves discussing its definition, purpose, and how it is used in statistics or data visualization.
Answer
A frequency curve is a smooth graphic representation of a data set's frequency distribution.
A frequency curve is a smooth graphic representation of the frequency distribution of a data set. It relates the magnitude of a variable to its frequency of occurrence and serves as a smoothed version of a histogram, often used in statistics and hydrology.
Answer for screen readers
A frequency curve is a smooth graphic representation of the frequency distribution of a data set. It relates the magnitude of a variable to its frequency of occurrence and serves as a smoothed version of a histogram, often used in statistics and hydrology.
More Information
Frequency curves help visualize the distribution of data and find the relationship between variables and their frequency. They are often used when working with continuous data and provide a clearer view compared to histograms as they smooth out the steps.
Tips
A common mistake is confusing frequency curves with histograms. Remember, frequency curves are smooth and help in understanding trends in continuous data.
