What is convenience sampling?5 answersConvenience sampling is a method of selecting participants for a study based on their accessibility to the researcher. It involves choosing individuals who are readily available and convenient to include in the sample. This type of sampling is commonly used in research, particularly in studies conducted on convenience or purposive samples. Convenience samples are drawn from a source that is easily accessible to the researcher, while purposive samples are selected based on specific characteristics relevant to the study. However, it is important to note that findings from studies using convenience samples can only be generalized to the population from which the sample is drawn and not to the entire population. Despite its limitations, convenience sampling is still widely used due to its convenience, lower costs, and ability to facilitate faster and more precise research.
What are sampling techniques used for?5 answersSampling techniques are used to select a subset or sample from a population for the purpose of making observations and drawing inferences about the entire population. The use of sampling reduces cost, time, and workload while still providing high-quality information that can be extrapolated to the population. It is important for the sample to be a true representation of the population to ensure that the inferences drawn from the analysis can be applied to the population. Sampling techniques eliminate bias in selecting the subset. Sampling is used in various fields such as social sciences, literary and historical research, design of experiments, image processing, and graphics. Different sampling techniques are used to meet the specific constraints of each field, such as uniform coverage or random samples that are a certain distance apart. In the context of power system analysis, sampling techniques are essential for probabilistic stability analysis and can be used to account for system uncertainties and fluctuating demands.
Amplifier feedback audio quality5 answersAn audio amplifier can improve audio quality through the use of feedback circuits. The negative feedback circuit of an audio frequency amplifier, as described by Liu Zhiqiang, includes components such as a light dependent resistor and a light-emitting diode to achieve automatic negative feedback quantity control and reduce adverse effects on the amplifier, loudspeaker, and sound quality. Zhenwu Wang's solid stage audio power amplifier utilizes a frequency dependent feedback selection network to create a unique global feedback loop, resulting in clear and tight bass at low frequencies and natural mid-band and treble at higher frequencies. Gerald R. Stanley's audio amplifier optimizes source impedance and utilizes a feedback control loop to minimize distortion in the loudspeaker, with a variable output impedance that changes from negative to positive at a determined threshold frequency. Vincent Mui, Lance Wong, and Aditya Raina's feedback amplifier includes operational amplifiers and resistors, with the ability to provide attenuation based on the configuration of switches. Juha Nurminen's method for improving the quality of the output signal of an audio output stage involves comparing a signal generated in the output stage to the digital input signal using feedback, and controlling the operation of the modulator circuit based on the digital control signal.
What is convenience sampling?3 answersConvenience sampling is a nonrandom sampling technique where the researcher selects participants based on their accessibility and convenience. It involves choosing individuals who are readily available and easily accessible to the researcher. The sample is drawn from a source that is conveniently accessible to the researcher, such as a specific location or a group of people. Convenience sampling is often used when time, resources, and workforce are limited, or when randomization is not possible. However, the findings from convenience sampling can only be generalized to the specific population or group from which the sample is drawn and cannot be applied to the entire population ^[Chittaranjan Andrade] ^[Ilker Etikan, Sulaiman Abubakar Musa, Rukayya Alkassim].
