Discussion Question on Variables
A variable is usually anything that can vary, change or be changed like attention, memory or time that is taken in performing a task. When looking at an independent variable it is a variable that is controlled, changed in a scientific experiment to ensure the effect of the dependent variable the dependent variable is thus a variable that is measured and tested in a scientific experiment (Omoregie and Adegbesan. In any case the dependent variable will often be dependent on the independent variable. An example if the independent and dependent variable is when a scientist want to see the brightness of light and whether it contains any effect on the moth being attracted to the light where the brightness of the light is being manipulated by the scientist (Leatham). In this regard, the light is going to be an independent variable, however how the moth will be responding is going to be a dependent variable.
