Example Experiments With Independent And Dependent Variables. In an experiment you manipulate the independent variable and measure the outcome in the dependent variable. In our example the independent variable has two levels. You want to know which brand of fertilizer is best for your plants. Locate an ant hill.
Locate an ant hill. In an experiment you manipulate the independent variable and measure the outcome in the dependent variable. Yes there can be more than one dependent variable. One level is a TV program with violence and the other level is a TV program without violence. Researchers systematically control and set the values of the independent variablesIn randomized experiments relationships between independent and dependent variables tend to be causal. You test different brands of popcorn to see which bag pops.
Independent and Dependent Variable Examples.
The dependent variable is the impact the drug has on cancer. Here are some other examples of dependent and independent variables in scientific experiments. 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. Locate an ant hill. Thus we have one dependent variable and one independent variable with two levels see Table 111. The dependent variable is the biomass of the crops at harvest time.
