French paradox refers to the fact that most people in France have a diet that is high in fat but still have lower rates of heart disease.
Frequency may be defined as the number of sound waves per second. In the case of a sound wave that repeats itself, such as the sine wave of a pure tone, Frequency is the number of times per second that the wave repeats itself.
Frequency distribution is defined as a plot of the number of scores occurring for each score value or for two (2) or more limited ranges of score values . It is an organized display of a set of scores that shows how many scores are located in each category on the scale of measurement ; the systematic arrangement of scores on a measure to reflect how frequently each value on the measure occurred. Moreover, Frequency distribution is defined as a description of the number of times the various attributes of a variable are observed in a sample. The report that 60 percent of a sample were married and 40 percent were single, is a simple example of a Frequency distribution.
Frequency spectrum is defined as a plot that indicates the amplitudes of the various harmonics that make up a complex tone. Each harmonic is indicated by a line that is positioned along the frequency axis , with the height of the line indicating the amplitude of the harmonic.
Frequency theory refers to a concept that pitch perception depends on differences in frequency of action potentials by auditory neurons; holds that tones up to 4,000 hertz are converted to nerve impulses that match the frequency of each tone.
