Laboratory Techniques
The application of proper laboratory techniques
improves the precision of data.
Scientific data that are used to analyze the characteristics of a chemical
or physical change must be collected with care and patience.
The data must be precise; that is, they must be reproducible to within
an “acceptable” margin of error.
A scientist who has good laboratory skills and techniques generally
collects good, reproducible data (called quantitative data). For that
reason, careful attention as to the method (or methods) and procedures
by which the data are collected is extremely important.
