RESEARCH STUDY 5.1: Dr. Rodriguez is considering conducting a study examining whether narcissistic people have poorer romantic r
elationships than those who are not narcissistic. One of her first tasks is to determine which of her participants are narcissistic and which are not. She decides to use the scale created by a colleague, the Donal scale. Question 1 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. Rodriguez is concerned whether her measure will really measure narcissism or if it will measure some other related concept. She is concerned about the scale’s ______________.
To understand this, let's define validity for better understanding
Validity can be define is the level to which a measurement, conclusion measurement or concept is well-collected and likely match accurately to the real world.
Dr Rodriguez main attention is focused on measuring the scale. Other measuring scale is not put into considering by her, as the validity of the measurement will measure the scale of narcissism.
In this example, Dr. Rodriguez is concerned about the scale's validity. Validity refers to the extent to which a measurement accurately corresponds with the real world. It particularly refers to whether this measurement does indeed measure what it intends to. In this example, this is what Dr. Rodriguez is concerned about, as she wanted her scale to measure narcissism and not another related concept.
Most things before the 1800s (when wide industry became a thing) were produced by hand tools and basic machines. Almost anything that was bought before the 1800s was hand made.
