When a football game is being played, a researcher counts how many times the coaches of the winning and losing teams yell at the referee. The technique used to quantify observations was called the frequency method.
<h3>
What is frequency method?</h3>
When the spectral content of a signal fluctuates with time, or when the signal is nonstationary, time-frequency approaches provide a handy method for describing that content. A bilinear (quadratic) representation results naturally from basing a representation on the decomposition of a signal's energy.
<h3>
Why do we use frequency analysis?</h3>
A component of descriptive statistics is frequency analysis. Frequency in statistics refers to the number of times an event takes place. Frequency Analysis is a crucial branch of statistics that examines measures of central tendency, dispersion, percentiles, etc. in relation to the quantity of occurrences (frequency).
