I need at least 15 pages in length done 10 pages should consist of valid references. You want to decide if the new diet will be associated with an increase in the average weight of the tadpoles. The independent variable for the tadpole diet experiment are the amount of food given to the tadpole, temperature, pH, density because an independent variable is defined as the variable that is changed or controlled in a scientific experiment .It represents the cause or the reson for an outcome (dependent variable) that is increase in the average weight. Independent and dependent variables are the two most important variables to know and understand when conducting or studying an experiment, but there is one other type of variable that you should be aware of: constant variables. If an experiment were comparing five types of diets, then the independent variable (type of diet) would . But you also have to be realistic about the cost of your experiment, and given that it costs millions of dollars to drill an oil well, youre likely to run this experiment on a smaller number of wells. It is the variable you control. In your experiment you keep all other factors, such as tadpole density per pan, temperature, pH, and the amount of food the same. The new diet is a meat-based food.

To better understand what a randomized controlled experiment is and how businesses use them, I talked with Tom Redman, author ofData Driven: Profiting from Your Most Important Business Asset. A lot of research on the cause of bleaching has focused on water temperature. Lets say youre in the business of drilling oil wells, and you have a new drill bit that is operated by an artificial intelligence program that adjusts the pressure and speed with which youre turning the bit. Think through all of the factors that could spoil your experiment for example, if the drill bits are attached to different types of machines or are used in particular types of wells. What is the independent variable? 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. Some plants are negatively phototropic ( go against light) while others are positively phototropic (go towards light). At the midpoint of the line connecting them, their combined electric field has a magnitude of 51N/C51 \mathrm{~N} / \mathrm{C}51N/C. Where can you perform the experiment phase of the scientiific method? Some of the values are missing from the table. The difficulty is that the value of both of these variables can change. When graphing these variables, the independent variable should go on the x-axis (the horizontal axis), and the dependent variable goes on the y-axis (vertical axis). But failing to do this means you could attribute the results to the wrong factors. Direct link to 47charbrow's post how come a prediction is , Posted 3 years ago. An easy way to keep the two variables straight is to use the acronym DRY MIX, which stands for: Students are often asked to identify the independent and dependent variable in an experiment. Ask questions; get answers. The dependent variable depends on the independent variable. Section: Experimentation and Data Analysis: Yeast Nutrition Topic: A View of Life; Scientific Method Learning Objective: 01.04. Both contain ten bean seeds planted in the same type of soil, and both are placed in the same window. and then to collect data. That seed may have been dead, unhealthy, or just slow to sprout. One diet is a meat-based fish food, and the other is the traditional diet of boiled lettuce. Tadpoles fed a meat-based diet will be bigger, but only if in a tank with low numbers. You want to see if the meat-based diet will be associated with an increase in the average weight of the tadpoles. On the other hand, the scientist has no control on the students' test scores. What is the independent variable for the tadpole diet experiment ? Want to improve your SAT score by 160 points or your ACT score by 4 points? The other pot of seeds doesn't get any water at all. Imagine that you wish to compare two different diets that will be fed to tadpoles raised in a lab. Revise the protocol based on what you learned in your pilot study. It's what changes as a result of the changes to the independent variable. In a controlled experiment, I postulate that, based on the null hypothesis, the tadpoles' weight will really either rise or decrease depending on their meals. The answers are at the bottom of the guide for you to check your work. ", Points on a straight line through (0,0) progressing upward and to the right. When researchers are interested in whether past diet as an independent variable may affect a dependent variable such as health status, they conduct a [glossary term:] retrospective study (also known as a case-control study) . what is the independent variable for the tadpole diet experiment? In a statistics experiment, the dependent variable is the event studied and expected to change whenever the independent variable is altered. 21, 1401 . The sooner in the process you collaborate, the more likely youll be able to gain from each others experience. An independent variable is defines as the variable that is changed or controlled in a scientific experiment. It includes 100+ ideas for experimentspick one that interests you and analyze what the different variables are in the experiment! An independent variable is defines as the variable that is changed or controlled in a scientific experiment. In the example regarding sleep and student test scores, it's possible the data might show no change in test scores, no matter how much sleep students get (although this outcome seems unlikely). The dependent variable (height) depends on the independent variable (age). 2 What is the trick to remembering the independent variable? Independent variables are the variables that the experimenter changes to test their dependent variable. Performance cookies are used to understand and analyze the key performance indexes of the website which helps in delivering a better user experience for the visitors. Thanks to that we guarantee high level of project management, consulting and services. The dependent variable is the variable that changes in response to the independent variable. In our oil well example, its the speed or efficiency with which you drill the well. what is the independent variable for the tadpole diet experiment? Now let's make a strategy. In the tadpole diet experiment, it would be sufficient to test only one single pan of tadpoles that were fed lettuce, and only one single pan of tadpoles fed meat. IBM is a global information technology company that offers a mix of products that are based on most advanced technology, including AI and cognitive computing. Turning, Method 3 of 3: Graphing Independent and Dependent Variables. Method 2 of 3: Identifying Variables in Equations. Independent and Dependent Variables - Organizing Your Social Sciences These cookies help provide information on metrics the number of visitors, bounce rate, traffic source, etc. B) The average weight for groups of bullfrog tadpoles is higher if density of tadpoles per gallon of . in the results obtained how does the subtraction of the control affect the results and why. what is the independent variable for the tadpole diet experiment? What might be influencing the dependent variable is the 'independent variable.'. The dependent variable (sometimes known as the responding variable) is what is being studied and measured in the experiment. 1 What question can you ask yourself to determine the independent variable? Question 3 Imagine that you wish to compare two different diets that will be fed to tadpoles raised in a lab. Experiment 1: You want to figure out which brand of microwave popcorn pops the most kernels so you can get the most value for your money. It's even possible for the dependent variable to remain unchanged in response to controlling the independent variable. ANSWER:- Tadpoles will be larger if fed a meat based diet. Independent Variable . How do you I stop my TV from turning off at a time dish? Where that data comes from and how we analyze it depends on a lot of factors for . Write a null hypothesis for this experiment the - Course Hero Redman says one of the biggest mistakes that companies make is simply not doing enough experiments not just randomized controlled experiments, but even more informal ones that are less costly and time intensive. 10 bean seeds are added to each pot. let make a strategy. Answer: The correct answer is - C. Tadpoles will be larger if fed a meat-based diet. Experiments are usually designed to find out what effect one variable has on another - in our example, the effect of salt addition on plant growth.. You manipulate the independent variable (the one you think might be the cause) and then measure the dependent variable (the one you think might be the effect) to find out what this . Create a graph with x and. Question 1 E) 10 In pillbug experiment 10 pillbugs are enough to have a good information about the experiment. What is the independent variable for an experiment comparing different tadpole diets? Independent Variable Definition and Examples. Panel 1: Two identical pots are prepared. The scientist is changing the type of fertilizer each plant gets which in turn changes how much each plant grows, but every other part of the experiment stays the same. The number of hours students sleep have no effect on their test scores. 29, 2021, thoughtco.com/definition-of-independent-variable-605238. Biology. Diet They're independent of everything else. Length of the experiment b. The . You can also think of the independent variable as the cause and the dependent variable as the effect. Researchers often manipulate or measure independent and dependent variables in studies to test cause-and-effect relationships. Making sure that you come up with a hypothesis that makes a true statement is by far the most important aspect of the scientific method.
