For example someone performing experiments on plant growth might report this hypothesis: "If I give a plant an unlimited amount of sunlight, then the plant will grow to its largest possible size.
Putting it in Action To help demonstrate the above principles and techniques for developing and writing solid, specific, and testable hypotheses, Sandra and Kristin, two of our staff scientists, offer the following good and bad examples.
In other words, you want to propose a hypothesis to use as the basis for an experiment.
Does the hypothesis relate an independent and dependent variable? Make sure your hypothesis is "testable. Independent variable: Dependent variable: 5. Related Links:. Kristin says: "This hypothesis is good because it is testable, simple, written as a statement, and establishes the participants troutvariables oxygen in water, and numbers of liceand predicts effect as oxygen levels go down, the numbers of lice go up.
Reading your hypothesis should tell a teacher or judge exactly what you thought was going to happen when you started your project. If I take my vitamins every day, then I will not feel tired.
Cause and Effect or 'If, Then' Relationships A good experimental hypothesis can be written as an if, then statement to establish cause and effect on the variables. It's not wrong or bad if the hypothesis is not supported or is incorrect.
You may find many studies similar to yours have already been conducted. A hypothesis is a statement, not a question. Included the independent and dependent variables in the hypothesis statement.
