For any episode of sleep, an individual is unable to directly estimate number of EEG arousals, quantity or proportion of N3 sleep, or other features of sleep macro or microstructure unavailable to consciousness. Equally, it is not clear how to compare a sleep quality rating judgement (e.g.,...
In mathematics, the mean value of a set of data or a population is also represented by the mean value. Usually, it is calculated by taking the ratio of the sum of each score given in the population and the number of scores in the population. For exam...
When the researcher has surety regarding the range (or the interval) in which the actual value of the model estimate lies, the range is known as the confidence interval. Greater certainty regarding the knowledge of the actual value of estimates warrants a shorter confide...
