Dependant Vs Independent Variables. The independent variable is the factor the researcher controls while the dependent variable is the one that is measured. You want to compare brands. Variables are given a special name that only applies to experimental investigations. Thus here the independent variable is the amount of light and the moths reaction is the dependent variable.
One is called the dependent variable and the other the independent variable. The independent and dependent variables are key to any scientific experiment but how do you tell them apart. In a study to determine whether how long a student sleeps affects test scores the independent variable is the length of time spent sleeping while the dependent variable is the test score. The variable being measured in an experiment that is dependent on the independent variable. You want to compare brands. On the contrary for more than one dependent variable there is always one independent variable.
You want to compare brands.
For example if we want to explore whether high concentrations of vehicle exhaust impact incidence of asthma in children vehicle exhaust is the independent variable while asthma is the dependent variable. Variables are given a special name that only applies to experimental investigations. Thus here the independent variable is the amount of light and the moths reaction is the dependent variable. Here the independent variable cause is the temperature while the amount of pigment or colour is the dependent variable the effect. An Independent variable is a variable whose value never depends on another variable whereas a dependent variable is a variable whose value depends on another variable. An easy way to think of independent and dependent variables is when youre conducting an experiment the independent variable is what you change and the dependent variable is what changes because of that.
