Question 1

Accepted Answer

A) True 
 B)False  False

Question 2

Explain why if a scale is found to be reliable,we CANNOT assume that it is also valid.

Accepted Answer

Reliability and validity are two different concepts in the field of measurement. Reliability refers to the consistency and stability of a measurement tool, while validity refers to the accuracy and truthfulness of the tool in measuring what it is intended to measure.

If a scale is found to be reliable, it means that it consistently produces the same results when used repeatedly under the same conditions. However, this does not necessarily mean that the scale is also valid. Validity is a more complex concept and requires evidence that the scale measures what it is supposed to measure accurately and truthfully.

There are several reasons why a reliable scale may not be valid. For example, a reliable scale could consistently measure the wrong thing, or it could be influenced by factors that are not relevant to the construct being measured. Additionally, a scale may be reliable within a specific population or context, but not valid for measuring the same construct in a different population or context.

In summary, while reliability is an important characteristic of a measurement tool, it is not sufficient on its own to ensure validity. Therefore, it is crucial to assess both reliability and validity when evaluating the quality of a measurement scale.

Question 18

Mr.Isle has noticed that several women he considers to be very feminine wear dresses or skirts often.Therefore,he decides he will determine a woman's degree of femininity by finding out how many times she wears a skirt or a dress over a period of a month.The women who wear dresses or skirts most frequently will be considered the most feminine; those who rarely wear either will be considered the least feminine.Is Mr.Isle's method of measuring femininity reliable? Why or why not? Is his method of measuring femininity valid? Why or why not? What is the tension that often exists between the criteria of reliability and validity?
