We can have selective reactions and specific reactions. Selective means “mostly”, or “almost all”. Specific means “all”. “Selective” implies that there are factors which favor one product over the other, while “specific” is usually a sign that there's something inherent to the mechanism that leads to only one product.

Methods and methodology. ... Understanding the difference between methods and methodology is of paramount importance. Method is simply a research tool, a component of research – say for example, a qualitative method such as interviews. Methodology is the justification for using a particular research method.

The main difference between the two sampling techniques is the proportion given to each stratum with respect to other strata. In proportional sampling, each stratum has the same sampling fraction while in disproportional sampling technique; the sampling fraction of each stratum varies.

Functions do specific things, classes are specific things. Classes often have methods, which are functions that are associated with a particular class, and do things associated with the thing that the class is - but if all you want is to do something, a function is all you need.

Specific. We need to yell that specific means something precise or of special application, while Pacific is an ocean.

A distinction of sampling bias (albeit not a universally accepted one) is that it undermines the external validity of a test (the ability of its results to be generalized to the rest of the population), while selection bias mainly addresses internal validity for differences or similarities found in the sample at hand.

The direct IF method uses a single-fluorophore-conjugated antibody directed against the target of interest. The indirect IF method uses two antibodies. The primary antibody is unconjugated. The secondary antibody is directed against the primary and has fluorescent marker.

The difference between the Gauss–Seidel and Jacobi methods is that the Jacobi method uses the values obtained from the previous step while the Gauss–Seidel method always applies the latest updated values during the iterative procedures, as demonstrated in Table 7.2.

The static method does not take any specific parameter. Class method can access and modify the class state. Static Method cannot access or modify the class state. The class method takes the class as parameter to know about the state of that class.

Differentiating between selection bias and generalizability – Selection bias refers to internal validity; generalizability is a matter of external validity. ... There is no valid interpretation available unless the selection bias is taken into account in the analysis or at least in the interpretation.

Selectivity refers to a drug's ability to preferentially produce a particular effect and is related to the structural specificity of drug binding to receptors. ... Specificity of drug action relates to the number of different mechanisms involved.
