The first step in the research process is

identifying a topic area and searching the literature to find a research question.

The results from an experiment allow researchers to conclude that there is a cause-and-effect relationship between two variables. On the other hand, a nonexperimental study simply allows researchers to conclude that a relationship exists. What conclusion was made in the Gillen-O'Neel et al. (2013) study?

increased study time is related to an increase in academic problems.. By the 10th and 12th grades, study time increasingly became associated with academic problems. Specifically, days with greater than average study time tended to be followed by days with more academic problems.

research participants.

Which of the following is typical of quantitative research? A. It involves measuring variables for each individual. B. It usually involves numerical scores. C. It uses statistical analysis to summarize and interpret results. D. All of the above.

D. All of the above.

A drawback of the method of tenacity is that it:

Does not allow for the correction of erroneous ideas. The method of tenacity does not allow for the correction of erroneous ideas.

One of the steps in the research process is to decide which research design to use. One possible research design is the between-subjects design, which involves comparing different groups of individuals. Another type of design is the within-subjects design, where the participants are repeatedly measured, often at different times. Which type of research design did Gillen-O'Neel et al. (2013) use?

Within-subjects design. The study begins with a large group of 9th-grade students. These students are measured in terms of the amount of sleeping time, studying time, and academic problems. Then, these same students are measured again in 10th grade. Another two years later, they are measured again in 12th grade.
