Frequency Curve
Understand the Problem
The question appears to be asking about the concept of a frequency curve, which relates to statistics and data representation. A frequency curve shows the distribution of data points across different ranges and is used to visualize the frequency of observations in a dataset.
Answer
A frequency curve is a smooth graphical representation of a data distribution related to variable magnitude and frequency.
A frequency curve is a smooth graphical representation of a data distribution, often derived from a histogram or a cumulative frequency curve, showing the relationship between a variable's magnitude and its frequency.
Answer for screen readers
A frequency curve is a smooth graphical representation of a data distribution, often derived from a histogram or a cumulative frequency curve, showing the relationship between a variable's magnitude and its frequency.
More Information
Frequency curves are important in statistics as they help estimate the cumulative distribution of a population, showing how often values occur in a data set.
Tips
Avoid confusing frequency curves with histograms; a frequency curve is a smoothed version and not a bar representation.
