Rounded down, R is 2, so a 2-log reduction is achieved. Conversely, an R-log reduction means that a reduction by a factor of 10 R has been achieved. Log reduction and percentage reduction. Reduction is often expressed as a percentage. The closer it is to 100%, the better. Letting c b and c a be as before, a reduction by P % is achieved, where
In probability theory and statistics, the coefficient of variation ( CV ), also known as normalized root-mean-square deviation (NRMSD), percent RMS, and relative standard deviation ( RSD ), is a standardized measure of dispersion of a probability distribution or frequency distribution. It is defined as the ratio of the standard deviation to the ...
Centimorgan. In genetics, a centimorgan (abbreviated cM) or map unit ( m.u.) is a unit for measuring genetic linkage. It is defined as the distance between chromosome positions (also termed loci or markers) for which the expected average number of intervening chromosomal crossovers in a single generation is 0.01.

In basketball, a FG% of .500 (50%) or above is considered a good percentage, although this criterion does not apply equally to all positions. Guards usually have lower FG% than forwards and centers. Field ...
A confidence interval for the parameter , with confidence level or coefficient , is an interval determined by random variables and with the property: The number , whose typical value is close to but not greater than 1, is sometimes given in the form (or as a percentage ), where is a small positive number, often 0.05.
