Most babies admitted to the NICU are premature (born before 37 weeks of pregnancy), have low birth weight (less than 5.5 pounds), or have a medical condition that requires special care.
Independent variable. An independent variable is used in statistics to predict or explain a dependent variable. For example, Age and Gender might be used as independent variables to predict the age of death or life expectancy (dependent variables). In experimental designs, the independent variables are manipulated by the researcher (e.g., different dosages of a drug).
an independent variable (IV) and dependent variable(s) (DVs). An Independent Variable is manipulated (controlled) by the experimenter, and has at least two different conditions (e.g., âtreatmentâ and âcontrolâ conditions). Experimental Research Dependent variablesare measured by the experimenter, and are used to determine the effect of the Independent Variable. In most experiments, researchers measure several dependent variables to learn the effect of the independent variable.
