For example, in Experiment 2 above, some of the constant variables would be the type of plant being grown, the amount of fertilizer each plant is given, the amount of water each plant is given, when each plant is given fertilizer and water, the amount of sunlight the plants receive, the size of the container each plant is grown in, and more. Suppose you have the speed on the x- axis and braking distance on the y-axis. Independent Variable Definition and Examples - ThoughtCo Warmers colors, mostly near the equator, represent hotter temperatures, while cooler colors, mostly near the poles, represent cooler temperatures. Imagine that you wish to compare two different diets that will be fed to tadpoles raised in a lab. But there are also lots of independent variables factors you suspect have an impact on your dependent variable. Helmenstine, Anne Marie, Ph.D. "Independent Variable Definition and Examples."

Similarly, when testing a new drug, you need to account for the placebo effect, where people get better simply because they think theyre getting treated, so you treat your control group the exact same as the treatment group, and you look for improvement in the treatment group relative to the control group. Once you have a protocol, Redman suggests you do a small-scale experiment to test out whether the process youve laid out will work.

Section: Experimentation and Data Analysis: Yeast Nutrition Topic: A View of Life; Scientific Method Learning Objective: 01.04. The other pot (control group) is not watered. Knowing the independent variable definition and dependent variable definition is key to understanding how experiments work. In your experiment you keep all other factors, such as tadpole density per pan, temperature, pH, and the amount of food the same. That's a great way of thinking about it. So move out of the lab quickly.. Practice Identifying the Independent Variable. So, the number of hours of sleep is the independent variable. Out of the ten watered bean seeds, only nine came up.

One is called the dependent variable and the other the independent variable. It would not be measurable. What do you do in the hypothesis phase of the scientific method? In this study, group of rats was fed with their standard diet while the other three groups were fed with a diet supplemented with blueberry, strawberry, and spinach powder, respectively . A good example of hypothesis testing based on observation comes from early studies of coral bleaching. Direct link to Brian F's post How do the sprouting seed, Posted 4 years ago. Helmenstine, Anne Marie, Ph.D. (2021, July 29). 0 like 0 dislike. The independent variable (sometimes known as the manipulated variable) is the variable whose change isn't affected by any other variable in the experiment. Where that data comes from and how we analyze it depends on a lot of factors for example, what were trying to do with the results, how accurate we need the findings to be, and how much of a budget we have.
