Paul spector (1981) provides a succinct definition stating, “a variable is a qualitative or quantitative entity that can vary or take on different values” (p.

Science variables definitions. What are variables in science? Any measurement of plant health and growth: In order to do so, scientists aim to make one change (the cause or independent variable) in order to determine if the variable is causing what is observed (the effect or dependent variable ).

Two important types of variables are: Variables are characteristics or conditions that exist in different amounts or types and can be changed in an experiment. A factor in a scientific.

A variable is a quantity that may be changed according to the mathematical problem. The generic letters which are used in many algebraic expressions and equations are x, y, z. A quantity that may assume any one of a set of values b :

We started off by cutting and pasting our “science variables” flap books into our. Variable definitions describe what researchers mean when they identify their variables. Definition of variable (entry 2 of 2) 1 a :

A symbol representing a variable 2 a : The three most essential variables in an experiment are the independent variable, dependent. The growth of a plant depends on the fertility of the soil, humidity, temperature and light.

Variables that represent the outcome of the experiment. Variables represents the measurable traits that can change over the course of a scientific experiment. An independent variable is the variable for which quantities are manipulated (selected or changed) by the experimenter, and assumed to have a direct effect on the dependent variable.
