In analytical health research there are generally two types of variables. The Members Of Each Pair Were Randomly Allocated, One To Each Diet. Because the Tadpoles will still be alive. The dependent variable changes in response to the change the scientist makes to the independent variable. Either the scientist has to change the independent variable herself or it changes on its own; nothing else in the experiment affects or changes it. Question: In An Experiment To Compare Two Diets For Fattening Beef Steers, Nine Pairs Of Animals Were Chosen From The Herd; Members Of Each Pair Were Matched As Closely As Possible With Respect To Hereditary Factors. You want to see if the meat-based diet will be associated with an increase in the average weight of the tadpoles. The new diet is a meat-based commercial fish food. Write an alternate hypothesis for this experiment: Based on the null hypothesis, I hypothesize that there will in fact be either an increase or decrease in the tadpoles weight base on their diets in a controlled experiment. In your experiment you keep all other factors, such as tadpole density per pan, temperature, pH, and the amount of food the same. Experiment example. The only difference between your control and experimental groups is the type of food the tadpoles receive What is the independent variable for the tadpole diet experiment? In an experiment there is only one independent variable. What is the independent variable? Diet. On the other hand, a dependent variable refers to the variable, which is being measured and tested in a scientific experiment. The independent variable (IV) is the characteristic of a psychology experiment that is manipulated or changed by researchers, not by other variables in the experiment. Dependent and Independent Variables. A variable, which is controlled or changed in a scientific experiment to examine the influences on the dependent variable is known as an independent variable. In experimental research, the independent variable is manipulated or changed by the experimenter to measure the effect of this change on the dependent variable.. 3) Some students consume large amounts of coffee and so-called energy drinks to help them stay alert when studying. 7.0 Explain why you chose that answer in the space below. Independent variables are what we expect will influence dependent variables. 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. lab conditions species of tadpole tadpole size Explanation The independent variable is the group that is being examined. A Dependent variable is what happens as a result of the independent variable. In your experiment you keep all other factors, such as tadpole density per pan, temperature, pH, and the amount of food the same. You are studying the impact of a new medication on the blood pressure of patients with hypertension.. To test whether the medication is … The independent variable (sometimes known as the manipulated variable) is the variable whose change isn't affected by any other variable in the experiment. You want to decide if the new diet will be associated with an increase in the average weight of the tadpoles. The independent variable are the variables in an experiment that are intentionally altered. PHOF Wher 4) Based on the data table and the graph, what is the optimum water pH for tadpole development? What is the independent variable for the tadpole diet experiment? One diet is a meat-based fish food, and the other is the traditional diet of boiled lettuce. 2) What is the independent Variable in this experiment? Independent and dependent variables in experiments. Number of la 3) What is the Dependent Variable in this experiment? The independent variable is the one that is changed by the scientist. As the scientist changes the independent variable, he or she observes what happens. For example, in an experiment looking at the effects of studying on test scores, studying would be the independent variable.
