What is the number of lone electron pairs on the central atom of a molecule having a linear molecular geometry, such as ClF2-?
Construct Validity
The degree to which a test measures what it claims, or purports, to be measuring. It is the degree to which the dependent measure assesses what it intends to assess or the manipulation of the independent variable manipulates what it intends to manipulate.
Independent Variable
In experimental research, the variable that is manipulated by the researcher to observe its effect on the dependent variable.
Dependent Variable
In experimental and statistical research, the variable being tested and measured, expected to change as a result of manipulations of the independent variable.
Limitation of Science
Constraints encountered in scientific research, such as biases, methodological errors, and the inability to provide absolute answers to all questions.
