Independent variables Examples. In other cases, researchers might find that changes in the independent variables have no effect on the variables … Independent variables are essential to scientific work and the scientific method. For example, in an experiment about the effect of nutrients on crop growth: The independent variable is the amount of nutrients added to the crop field. The independent variable is also known as a controlled variable or predictive variable depending on the type of study. 89 examples: Each coefficient of a probit regression stands for the impact of the… independent-variable. In other words, the independent variable is the variable that is being tested or altered by the experimenter. The independent variables are just those variables that may influence or affect the other variable, i.e., the dependent variable. Examples of independent variable in a sentence, how to use it. Mini-quiz 1. Independent variables. The independent variable in this example is the type of therapy. In an experiment, you manipulate the independent variable and measure the outcome in the dependent variable. The dependent variable is the biomass of the crops at harvest time. For example, in the first phenomenon of climate change, temperature (independent variable) may influence sea level (dependent variable). Examples of independent variables depend on the nature of the experiment, and some of these variables with experiments are: In an experiment testing the behavior of moths to light and dark by turning the light on and off, the light is the independent variable. This factor is often the research question/hypothesis behind the outcome of the experiment. Sometimes varying the independent variables will result in changes in the dependent variables. The independent variable is controlled or changed only by the researcher. An independent variable in an experimental setup is the manipulated variable. Independent-variable sentence examples. Impact . Dependent variable It is the changeable factor within the study whose behavior ends up being affected by the factors that the experimenter manipulates. In the above example, the researcher may have wanted to see if participating in the training program raised students' scores on a final test. An antecedent variable is a variable that occurs before the independent and dependent variables under study and can help explain the relationship between the two. You can remember this definition by remembering that the word antecedent literally means “previous or preexisting.” Examples of Antecedent Variables Variable or predictive variable depending on the type of study no effect on the type of study or.
