Answer to Question 1

ANS: A
Bias means a slant or deviation from the true or expected. Bias in a study distorts the findings from what the results would have been without the bias. Because studies are conducted to determine the real and the true, researchers place great value on identifying and removing sources of bias in their study or controlling their effects on the study findings.
Manipulation is when the researcher does something with one of the variables.
Multicausality is the interrelatedness of many concepts within a phenomenon under study.
Probability is the likelihood of an event to occur within a given situation.

Answer to Question 2

ANS: D
Probability addresses relative rather than absolute causality.
Absolute would imply certainty, and probability would not be involved. Probability addresses relative rather than absolute causality.
Conclusive means that there is no doubt. Probability addresses relative rather than absolute causality.
Definite means certainty and does not involved probability. Probability addresses relative rather than absolute causality.
