The A1C test is a blood test that returns a number (for example, 6%) that reflects how well a person's blood sugar levels have been controlled over the last several months. The researcher randomly assigned the 60 participants into three conditions: placebo group (no medication), 100 mg of medication, or 200 mg of medication. At the end of 30 days, the A1C levels of each participant was measured. A professor is interested in whether a research mentoring program can help students gain admission to graduate school.

A method for predicting IQ as soon as possible after birth could be important for early intervention in cases such as brain abnormalities or learning disabilities. It has been thought that greater infant vocalization (for instance, more crying) is associated with higher IQ. In 1964, a study was undertaken to see if IQ at 3 years of age is associated with amount of crying at newborn age. In the study. 38 newborns were made to cry after being tapped on the foot and the number of distinct cry ions within 20 seconds was counted. The subjects were followed up at 3 years of age and their IQs were measured.
