Answer: Option (C). Validity

Explanation: Validity is the degree to which a variable, test, questionnaire or instrument measures the theoretical concept that the researcher hopes to measure. validity is an indication of how sound your research is. More specifically, validity applies to both the design and the methods of your research. Validity in data collection means that your findings truly represent the phenomenon you are claiming to measure.

Furthermore, Validity referred to the extent to which the scores from a measure represent the variable they are intended to. When a measure has good test-retest reliability and internal consistency, researchers should be more confident that the scores represent what they are supposed to. In other to assess whether a study has construct validity, a research consumer should ask whether the study has adequately measured the key concepts in the study.

Fantasia believes that people with blue eyes are somehow more creative than other people. Whenever Fantasia encounters a person
Ksju [112]

The correct answer would be option A, Confirmation Bias.

At the same time, Fantasia ignores any evidence that people without blue eyes might display exceptionally creativity. This is called a Confirmation Bias.

Explanation:

When a person gives more importance to new evidence that supports his already existing belief, it is called as the Confirmation Bias.

In psychology, it is a tendency of a person to search and support for evidences in order to confirm his preconceptions.

When a person has a direct influence of his own desires on beliefs and concepts, confirmation bias is most likely to occur. It means that when people desire to have a certain idea or concept to be true, they end up believing it to be true.

Just given in the question, Fantasia believes that people with blue eyes are more creative than other people having any other eye color, and when she meets a person with blue eyes who is really creative, her belief gets stronger and she puts more importance to her evidence supporting her already existing belief. At the same time, she ignores any evidence that people without blue eyes might display exceptional creativity. This is the Confirmation Bias.

I'd say that 

C. a stone carving, is the correct answer because a reed basket, pieces of clothing and clay plots would be most likely made by women.

I don't think women have the strength to do stone carvings, it also seems like the mans job.

Hope this helps.
