Costs
Every research is carried with the hope of getting reliable data that would enable success in the study. Value is an independent variable that is involved in almost all tasks. In the Chicago longitudinal study case, the project costs a considerable amount of money to start or maintain completion. The panel design and cohort design used in the study involved many costs as it was to cover a lot of students, that is 1539. It started in 1986; 25 years later, the task is still on course. A lot of money must have been injected into the project to ensure success.
Richness of data
The study was carried over a large number of children, 1539, plus over a long period. It meant a lot of data is obtained from the research. Such data would help the project succeed in getting to evaluate the CPC impacts on child development. The study employed a panel study that ensured data was collected in at least two samples—providing the survey with the much-needed depth of data. The project’s also used the cohort design, which ensured data was gotten from the same category of people over some time. In the Chicago longitudinal study, they took only a sample of 1539 who started schooling together, providing rich, consistent data.
Design issues this type of project might pose
Research projects always have shortcomings that need to be addressed. Chicago longitudinal study also had some design issues resulting from it (Smerillo et al., 167). They are selective attrition and inadequate financing. The project needed a lot of money to push through owing to its nature of coverage. It covered a long duration and many participants. Selective attrition meant that some of the participants might opt out of the study before it finalizes. Reasons would be some moving out of the area, getting sick, and lack of motivation, and, in some cases, death.
