Imagine that you wish to compare two different diets that will be fed to tadpoles raised in a lab. When scientists design experiments, they determine what will be their independent, dependent, and constant variables. Here is an example of an experiment: Researchers examined the effect of pesticides on tadpole limb development. The only difference between your control and experimental groups is the type of food the tadpoles receive . Answer (1 of 2): When you are running an experiment the independent variables are those you directly control or vary.The dependent variables are those you only measure or try to observe*. Diet. The dependent variable is the variable that changes in response to the independent variable. The dependent variable is the variable that is being measured or tested in an experiment. It is called independent because its value does not depend on and is not affected by the state of any other variable in the experiment. Researchers are trying to determine if changes to the . They were not orienting themselves with regard to any particular stimulus. In your experiment you keep all other factors, such as tadpole density, temperature, pH, and the amount of food, constant. For example, when investigating the effect of study time of performance, the study time is the independent variable. An independent variable is the variable that is changed in a scientific experiment. Control Group = Those participants treated just like the experimental group EXCEPT they are not. Identify independent variables: Imagine that you wish to compare the two different diets that will be fed to tadpoles raised in a lab. The experiments and process should be unbiased and orderly, and the results should be repeatable. Researchers often manipulate or measure independent and dependent variables in studies to test cause-and-effect relationships. Imagine that you want to compare a new diet for tadpoles that are reared in the laboratory to the traditional laboratory diet of boiled lettuce. The new diet is a meat-based food. 2. The independent variable is the glass, and the dependent variable is the plexiglass. Control variables are variables that must be kept the same in an experiment. Every experiment should have only one independent variable. -Diet will have no effect on tadpole size. You want to see if the meat-based diet will be associated with an increase in the average weight of the tadpoles. experimental and control. Its value depends on changes in the independent variable.

The two variables may be related by cause and effect. Question 3 Imagine that you wish to compare two different diets that will be fed to tadpoles raised in a lab. . Answer. You have just finished weighing a pan of tadpoles at the conclusion of your experiment in which you sought to determine whether tadpoles that were fed the meat-based diet grew significantly larger than tadpoles who were fed boiled lettuce. One diet is a meat-based fish food, and the other is the traditional diet of boiled lettuce. What was the independent variable in this experiment? Its value is independent of other variables in your study. An example of a dependent variable is depression symptoms, which depends on the independent variable (type of therapy). 1 For example, in a study looking at how tutoring impacts test scores, the dependent variable would be the participants' test scores, since that is what is being measured. Independent variables are the variables that the experimenter changes to test their dependent variable. Imagine that you wish to compare two different diets that will be fed to tadpoles raised in a lab. Tadpole Experiment 1. An independent variable is a variable, often denoted by x, whose variation does not depend on that of another variable. In a purely observational study the independent variables are those you believe are causative, and the indep. What is the independent variable for the tadpole diet experi-ment? Independent variables are the variables that the experimenter changes to test their dependent variable. In a statistics experiment, the dependent variable is the event studied and expected to change whenever the independent variable is altered.
