Explanation:
(a) Experimental unit
A person or an object, or some well-defined body or item on which some treatment is applied
(b) Treatment
Combination of a values of factors. These are explanatory variables.
(c) Response variable
The qualitative variable or quantitative variable in which the researcher wants to determine how the value is affected by any explanatory variable.
(d) Factor
It is the variable whose influence on a response variable can be assessed by the researcher.
(e) Placebo
An innocuous treatment, like a sugar tablet, which looks, smells and tastes like an experimental medication.
(f) Confounding

Answer:
a. the Pope refused to grant him an annulment and he wanted more power

The pope refused to annul his marriage, and so he split with the Catholic church and made a new Anglican church, recognizing his and Ann's marriage, and invalidating the claims of Princess Mary.
<u>External</u> validity is the extent to which findings may be generalized, while <u>internal </u>validity refers to the ability to infer that there is a causal relationship between variables.
Internal validity is the degree to which the observed effect can be reliably attributed to the independent variable. Internal validity is attained if only the independent variable(s) are responsible for the dependent variable's effect. This is the level of manipulation that can be applied to a result. In other words, internal validity is a measure of how well your research "works" in a research environment. Does the variable you alter inside a particular study have an impact on the variable you're examining?
The term "external validity" describes how far a study's findings can be extrapolated from the sample. Which means you may use the information you learn to make adjustments for different scenarios and people. Consider this as the extent to which a result can be generalized. How well do the research findings translate to the rest of the world? A controlled environment with fewer variables is a laboratory setting (or other research setting). The term "external validity" describes how well the findings stand up in the presence of all those other variables.
