Signal-to-noise ratio (SNR) is a measure that compares the level of a desired signal to the level of background noise in a given system. A higher SNR indicates that the signal is clearer and more distinguishable from the noise, which is crucial in data analysis as it directly affects the quality of results. In the context of data preprocessing and normalization, achieving a favorable SNR is essential for accurately interpreting complex biological data, as it ensures that meaningful variations are detected while minimizing the impact of random fluctuations or errors.
