I discuss points of agreement and disagreement with Francis (2013), and argue that the main lesson from his numerous one-off publication bias critiques is that developers of new statistical tools ought to anticipate their potential misuses and develop safeguards to prevent them. © 2013 Elsevier Inc.

Two misuses of one-time pad in improving the efficiency of quantum communication are pointed out. One happens when using some message bits to encrypt others, the other exists because the key bits are not truly random. Both of them result in the decrease of security. Therefore, one-time pad should be used carefully in designing quantum communication protocols.

The present review introduces methods of analyzing the relationship between two quantitative variables. The calculation and interpretation of the sample product moment correlation coefficient and the linear regression equation are discussed and illustrated. Common misuses of the techniques are considered. Tests and confidence intervals for the population parameters are described, and failures o...
