. In the former, nearly everybody is going to give the exact same answer, while the latter will give a lot of variation in responses. Simply put, when your variables do not have a lot of variance, larger sample sizes make sense. Statistical significance The likelihood that the results of...

Infrared JHK photometry and spectral types have been obtained for a sample of long-period variables in, and to the north of, the bar of the LMC. It is found that the carbon stars and the oxygen-rich stars obey different period-luminosity relations. The period-luminosity distribution of the ...
Sample-size determination for achieving asymptotic stability of a double EWMA control scheme Illustrative examples demonstrate the effectiveness of the covariance structure of I-O variables in determining the sample size. Implications for research on ... ST Tseng,NJ Hsu - 《IEEE Transactions on Semicon...
In subject area: Computer Science Sample correlation refers to the measure of the strength and direction of a linear relationship between two variables, calculated using a sample data set. It is represented by the correlation coefficient (rxy) and is used to determine the degree of association bet...
The input parameters consists of furan, acidity, moisture, IRT, dielectric strength, tan delta and DGA; each is characterized by two variables, i.e., its magnitude and change rate. If the database has a large volume, the FL model yields more reasonable results. Nevertheless, only three ...
In conclusion, the study supports use of the FSFI for assessing sexual function not only in clinical samples but also in population based samples. The associations found between sexual function and other important variables showed the complexity of sexual function. 展开 ...
Social determinants of alcohol consumption: the effects of social interaction and model status on the self-administration of alcohol. Two studies were conducted to assess variables related to the social determinants of alcohol consumption. In Study 1, moderate- and heavy-drinking male und... RL ...
