might not have used random assignment 1.44 Ability and wages: Arcidiacono, Bayer, and Hizmo (2008) analyzed data from a national longitudinal sur- vey called NLSY79, which includes data from more than 12,000 men and women in the United States who were in the 14- to 22-year age range in 1979. The researchers reported that ability is related to wages in early career jobs for university graduates but not for high school graduates. In line with this, research has found that racial discrimination with respect to wages is more prevalent against high school graduates than college graduates, because when ability is not the primary reason for determining wages, other factors irrelevant to ability, such as race, play in. The research- ers suggest that their findings might explain why, on average, a black person is more likely to earn a college degree than is a white person of the same ability level. a. List any independent variables b. List any dependent variables. c. What is the sample in this study? d. What is the population about which researchers want to draw conclusions? e. What do the authors mean by "longitudinal" in this study? f. The researchers used the Armed Forces Qualifica- tion Test (AFQT) as their measure of ability. The AFQT combines scores on word knowledge, para- graph comprehension, arithmetic reasoning, and mathematics knowledge subscales graduates to high school graduates? searchers might have operationalized ability at least one confounding variable in the relation between ability and wages when comparing college g. Suggest at least two other ways in which the re- PreviewExplanation / Answer
In an experiment the researcher is looking for the possible effect on the dependent variable that might be caused by changing the independent variable. Independent variable ,the experimenter manipulates assumed to have a direct effect on the dependent variables.
Studying of data between the age groups is defined as independent variable from the given senior's.
Almost we have to study 12000 men & women for getting best output for the survey.
A dependent variable whose values depend on other variables.
The dependent variable is wage from the given hypothesis. Since wage is depending on so many factors.
From the given population , we are concentrating between 18 to 22 age group people. We are applying methods of samples for 18 to 22 age group people for getting better results .
From the given hypothesis ,Longitudinal means measuring parameters on social behavioral sciences.
Researcher define constructs both conceptually and operationally.
In conceptual we have to make our abstract concepts concrete so we can study them.
Operational definition constructs by specifying the procedures used to measuring parameter.
