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).
Summary of Differences. 1  In science, for one independent variable, there may be more than one dependent variable. 2  The value of an independent value can be changed. 3  The independent variable is the value which is manipulated in an experiment. The dependent variable is the value observed by the researcher during an experiment. Knowing the differences between independent and dependent variables will help as you as you sharpen your problem solving skills and continue to explore new concepts within the fields of mathematics and the science.
