We have heard of many hypotheses which have led to great inventions in science. Assumptions that are made on the basis of some evidence are known as hypotheses. In this article, let us learn in detail about the hypothesis and the type of hypothesis with examples. Show
What is Hypothesis?A hypothesis is an assumption that is made based on some evidence. This is the initial point of any investigation that translates the research questions into predictions. It includes components like variables, population and the relation between the variables. A research hypothesis is a hypothesis that is used to test the relationship between two or more variables. Characteristics of HypothesisFollowing are the characteristics of the hypothesis:
Sources of HypothesisFollowing are the sources of hypothesis:
Types of HypothesisThere are six forms of hypothesis and they are:
Simple HypothesisIt shows a relationship between one dependent variable and a single independent variable. For example – If you eat more vegetables, you will lose weight faster. Here, eating more vegetables is an independent variable, while losing weight is the dependent variable. Complex HypothesisIt shows the relationship between two or more dependent variables and two or more independent variables. Eating more vegetables and fruits leads to weight loss, glowing skin, and reduces the risk of many diseases such as heart disease. Directional HypothesisIt shows how a researcher is intellectual and committed to a particular outcome. The relationship between the variables can also predict its nature. For example- children aged four years eating proper food over a five-year period are having higher IQ levels than children not having a proper meal. This shows the effect and direction of the effect. Non-directional HypothesisIt is used when there is no theory involved. It is a statement that a relationship exists between two variables, without predicting the exact nature (direction) of the relationship. Null HypothesisIt provides a statement which is contrary to the hypothesis. It’s a negative statement, and there is no relationship between independent and dependent variables. The symbol is denoted by “HO”. Associative and Causal HypothesisAssociative hypothesis occurs when there is a change in one variable resulting in a change in the other variable. Whereas, the causal hypothesis proposes a cause and effect interaction between two or more variables. Examples of HypothesisFollowing are the examples of hypotheses based on their types:
Functions of HypothesisFollowing are the functions performed by the hypothesis:
How will Hypothesis help in the Scientific Method?Researchers use hypotheses to put down their thoughts directing how the experiment would take place. Following are the steps that are involved in the scientific method:
Frequently Asked Questions – FAQsA hypothesis is an assumption made based on some evidence. Consumption of sugary drinks daily results in obesity. This is an example of a simple hypothesis. Types of hypothesis are: State true or false: Hypothesis is the initial point of any investigation that translates the research questions into a prediction.True. Define complex hypothesis.A complex hypothesis shows the relationship between two or more dependent variables and two or more independent variables. What is meaning of hypothesis in research?A hypothesis is an assumption that is made based on some evidence. This is the initial point of any investigation that translates the research questions into predictions. It includes components like variables, population and the relation between the variables.
What is hypothesis and its example?A simple hypothesis is a statement made to reflect the relation between exactly two variables. One independent and one dependent. Consider the example, “Smoking is a prominent cause of lung cancer." The dependent variable, lung cancer, is dependent on the independent variable, smoking.
What is the simplest definition of hypothesis?A hypothesis (plural: hypotheses), in a scientific context, is a testable statement about the relationship between two or more variables or a proposed explanation for some observed phenomenon.
What is the 3 types of hypothesis?Types of research hypotheses. Alternative Hypothesis. The alternative hypothesis states that there is a relationship between the two variables being studied (one variable has an effect on the other). ... . Null Hypothesis. ... . Nondirectional Hypothesis. ... . Directional Hypothesis.. |
