Dr. Rodriquez is considering conducting a study examining whether narcissistic people have poorer romantic relationships than those who are not narcissistic. To measure narcissism, she uses a narcissism scale created by a colleague. Question 1 of the scale reads, I tend not to think about other people as much as I think about myself. Question 2 reads, I do not have a high opinion of myself. Question 3 reads, I think other people think I am really special. Dr. Rodriquez is concerned whether the scale will really measure narcissism or if it will measure some other related concept. In short, she is concerned about the scale s .

In short, she is concerned about the scale' s validity.

Explanation:

If Dr. Rodriquez is concerned about whether the scale will actually be able to measure narcissism, which is the main object of the research, he is concerned about whether the results presented by the scale will be truthful, that is, he is concerned about the veracity of scale, which is the capacity of that scale to present real and true results and thus promote efficient research.

levels of production can be increased by technology while holding labor and capital constant, because increased technology makes the production process more efficient. subsequently, the lras curve is almost a vertical line, that can shift to the right, with an increase in technology.

the relationship between the lras curve and the ppc is that both can make the economy could grow. the ppc achieves that when it shifts outward because of more resources or technological advances while the lras curve shifts if more resources are developed or if there are technological advances.

the lras curve is a vertical line at an output level that represents the number of goods and services a nation can produce over a sustained period using all of its productive resources as efficiently as possible with all of the current technology available to it.

the production possibilities frontier (ppf) is a graphical device that is used for economic analysis of production decisions because the ppf measures the maximum possible combinations of two goods that an economy is capable of producing with its currently available resources and technology.
