Often called a research question, a hypothesis is basically an idea that must be put to the test . Research questions should lead to clear, testable predictions. The more specific these predictions are, the easier it is to reduce the number of ways in which the results could be explained.
What are hypotheses quizlet?
hypothesis. A tentative and testable explanation of the relationship between two (or more) events or variables ; often stated as a prediction that a certain outcome will result from specific conditions.
Which of the following is one of the purposes of hypothesis?
The purpose of a hypothesis is to find the answer to a question . A formalized hypothesis will force us to think about what results we should look for in an experiment. The first variable is called the independent variable.
What are examples of hypothesis?
Simple Hypothesis Examples
A simple hypothesis predicts the relationship between two variables: the independent variable and the dependent variable. This relationship is demonstrated through these examples. Drinking sugary drinks daily leads to being overweight . Smoking cigarettes daily leads to lung cancer.
What are hypotheses?
An hypothesis is a specific statement of prediction . ... There is no formal hypothesis, and perhaps the purpose of the study is to explore some area more thoroughly in order to develop some specific hypothesis or prediction that can be tested in future research. A single study may have one or many hypotheses.
What is hypothesis and its importance?
A hypothesis is used in an experiment to define the relationship between two variables . The purpose of a hypothesis is to find the answer to a question. A formalized hypothesis will force us to think about what results we should look for in an experiment. The first variable is called the independent variable.

Is a hypothesis the same as a theory?
A hypothesis is an educated guess or prediction about the relationship between two variables . ... But, because theory is a result of scientifically rigorous research, it is more likely that the theory is true (as compared to a single hypothesis).
What type of statement is a hypothesis?
A hypothesis is a tentative statement about the relationship between two or more variables . It is a specific, testable prediction about what you expect to happen in a study.
What is the definition of a scientific hypothesis quizlet?
A scientific hypothesis is a proposed scientific explanation for specific observations or an experiment . ... Some hypothesis are tested by getting more data and others are tested by doing experiments.
What is a hypothesis easy definition?
A hypothesis is an assumption , an idea that is proposed for the sake of argument so that it can be tested to see if it might be true. ... A hypothesis is usually tentative; it’s an assumption or suggestion made strictly for the objective of being tested.

- If I add fertilizer to my garden, then my plants will grow faster.
- If I brush my teeth every day, then I will not develop cavities.
What are the 3 types of hypothesis?

- Complex Hypothesis.
- Working or Research Hypothesis.
- Null Hypothesis.
- Alternative Hypothesis.
- Logical Hypothesis.
- Statistical Hypothesis.
What do all hypotheses have in common?
The two primary features of a scientific hypothesis are falsifiability and testability , which are reflected in an “If...then” statement summarizing the idea and in the ability to be supported or refuted through observation and experimentation.
What are the two main categories of hypotheses?
In research, there is a convention that the hypothesis is written in two forms, the null hypothesis, and the alternative hypothesis (called the experimental hypothesis when the method of investigation is an experiment).
Is a hypothesis a prediction?
defined as a proposed explanation (and for typically a puzzling observation). A hypothesis is not a prediction . Rather, a prediction is derived from a hypothesis. A causal hypothesis and a law are two different types of scientific knowledge, and a causal hypothesis cannot become a law.
