A researcher,based on her review of relevant scientific studies,believes that there is a relationship between the frequency of a baby's crying and whether it was nursed at set intervals or on a demand schedule.If this belief were tested by experimentally manipulating feeding schedules,the feeding schedule would be called the:
A)independent variable.
B)dependent variable.
C)extraneous variable.
D)control factors.

Question

Quizplus · Accepted Answer

The feeding schedule is the independent variable in this scenario because it is being manipulated to see if it has an effect on the frequency of the baby's crying. The dependent variable would be the frequency of the baby's crying, as it is the outcome being measured. Extraneous variables are other factors that can influence the outcome and need to be controlled for in the experiment. Control factors are the procedures or conditions that are kept consistent throughout the experiment, to ensure that the independent variable is the only factor that is being changed.
