relative frequency approach

Axiomatic approach to probability closely relates the theory of probability to set theory. Let S be the sample space of an experiment. Probability is a function, which associates a non-negative real number to every event A of the sample space denoted by P(A) satisfying the foll..

Wave velocity is defined as the distance traveled by the wave in one second. Or Wave velocity = Wavelength frequency..

In frequency modulation, the deviation of the carrier frequency from its average value is proportional to the instantaneous amplitude of the modulating signals. When the signal voltage is zero, the carrier frequency is unchanged. When the signal approaches it..

Which of the following statement(s) is/are false? I. Data such as blood types (A, B, AB, O) can be organised into a categorical frequency distribution. II. Except for rounding errors, relative frequencies should add up to 100. III. A statistical device used in explorat..

Doppler Effect - Let a stationary observer on a platform listen to the sound emitted by the whistle of an incoming train. As the train approaches the platform, an increase in the pitch of the sound will be observed. As the engine moves away from him, there will be a decrease in the pitch ..

Whenever there is a relative motion between a source of light and the observer, the apparent frequency of light received by the observer is different from the true frequency of light emitted actually from the source of light. If a source of light emits waves of fr..

As the threshold of audibility varies with frequency, sounds of the same intensity but different frequencies are found to differ in loudness. Therefore, another unit of loudness is defined. This unit measures the intensity of a sound relative to a reference tone ..

. Two stars which revolve around one another are called double stars or spectroscopic binaries. When one is approaching the Earth, the other will be receding and this causes a split in the spectral lines, due to change in the frequency of the light emitted. The phenomenon of red..

Phon - Another Unit of Loudness - As the threshold of audibility varies with frequency, sounds of the same intensity but different frequencies are found to differ in loudness. Therefore, another unit of loudness is defined. This unit measures the intensity of a sound relati..
