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 is the variable that is changed in a scientific experiment. Independent variables are the variables that the experimenter changes to test their dependent variable. For example, a scientist is testing the effect of light and dark on the behavior of moths by turning a light on and off.he independent variable is the amount of light and the moth's reaction is the dependent variable. A change in the independent variable directly causes a change in the dependent variable.
