In one study, Craig Ramey and his colleagues randomly assigned 111 young children from low-income, poorly educated families to either an intervention group, which received full-time, year round day care long with medical and social work services, or a control group, which received medical and social benefits but no day care. The day-care program included gamelike learning activities aimed at improving language, motor, social, and cognitive skills. The success of the program in improving IQ was evident by the time the children were 3 years of age. find the IV and DV

Answers

Answer 1

Answer: The independent variable (IV) in this study is the type of care received by the children: either full-time, year-round day care with medical and social work services (intervention group) or medical and social benefits but no day care (control group).

The dependent variable (DV) is the children's IQ, which was used to measure the success of the program in improving their cognitive skills.

Explanation: The IV is manipulated by the researchers to determine its effect on the DV. In this case, the researchers wanted to see if the full-time, year-round day care with additional services would have a positive impact on the children's IQ, compared to the control group who only received medical and social benefits. The DV was measured at the end of the study to determine the effectiveness of the intervention.

What is meant by an external background check?

An external background check may be characterized as a type of inspection of a potential employee that an outside organization performs. Neither the employer nor the employee provides this background check. Instead, an unbiased and unaffiliated company does so.

There are many reasons behind this process, but the common and major objective of background checks is to ensure the safety and security of the employees in the organization.

These checks are often used by employers as a means of judging a job candidate's past mistakes, character, and fitness, and to identify potential hiring risks for safety and security reasons.
