An empirical hypothesis, or working hypothesis, comes to life when a theory is being put to the test, using observation and experiment.

It's no longer just an idea or notion. It's going through some trial and error and perhaps changing around those independent variables. A statistical hypothesis is an examination of a portion of a population or statistical model. In this type of analysis, you use statistical information from an area. For example, if you wanted to conduct a study on the life expectancy of Savannians, you would want to examine every single resident of Savannah.

This is not practical. Therefore, you would conduct your research using a statistical hypothesis or a sample of the Savannian population. For a hypothesis to be sound , hold tight to these tips. Define the independent and dependent variables very specifically, and don't take on more than you can handle. Keep yourself laser-focused on one specific cause-and-effect theory. Keep your language clean and simple. State your hypothesis as concisely, and to the point, as possible. A hypothesis is usually written in a form where it proposes that, if something is done, then something else will occur.

Usually, you don't want to state a hypothesis as a question. You believe in something, and you're seeking to prove it. For example: If I raise the temperature of a cup of water, then the amount of sugar that can be dissolved in it will be increased. Any hypothesis will need proof. Your audience will have to see evidence and reason to believe your statement.

For example, I may want to drink root beer all day, not green tea. If you're going to make me change my ways, I need some sound reasoning and experimental proof — perhaps case studies of others who lost weight, cleared up their skin and had a marked improvement in their immunity by drinking green tea. Scientists can really change the world with their hypotheses and findings. To improve the world we live in, all it takes is an initial hypothesis that is well-stated, founded in truth and can withstand extensive research and experimentation.

Seek out your independent and dependent variables and go on out there and make this world a better place. Home Examples Examples of Hypothesis. Types of Hypothesis Before diving into hypothesis examples, you must take a moment to understand independent and dependent variables. For example: How does the amount of makeup one applies affect how clear their skin is? Here, the independent variable is the makeup, and the dependent variable is the skin. Simple Hypothesis Examples A simple hypothesis predicts the relationship between two variables: the independent variable and the dependent variable.

Drinking sugary drinks daily leads to obesity. Smoking cigarettes daily leads to lung cancer. Getting 8 hours of sleep can lead to more alert students. Complex Hypothesis Examples A complex hypothesis has a relationship between variables. Overweight adults who 1 value longevity and 2 seek happiness are more likely than other adults to 1 lose their excess weight and 2 feel a more regular sense of joy. Individuals that 1 smoke cigarettes and 2 live in cities are more likely than others to have 1 respiratory problems and 2 increased cancer.

Overweight individuals who 1 eat greasy foods and 2 eat few vegetables are more likely to have 1 high cholesterol and 2 heart disease. Null Hypothesis Examples A null hypothesis H0 exists when a researcher believes there is no relationship between the two variables or a lack of information to state a scientific hypothesis.

There is no significant change in my health during the times when I drink green tea only or root beer only. There is no significant change in my work habits when I get 8 and when I get 9 hours of sleep.

In your dissertation, you may create a hypothesis based on your research that predicts a relationship, called an "alternative" or "research" hypothesis. To balance your findings, you will also create a "null" hypothesis, which claims that the relationship that is to be proven in the research hypothesis does not exist. There can also be types of research hypotheses. As indicated in Research Methods Knowledge Base, a "one-tailed" hypothesis specifies a direction, either an increase or a decrease, while a "two-tailed" hypothesis does not specify a direction, only a change.

You must write your dissertation hypotheses before you collect and analyze your data. A useful hypothesis as testable and should include the independent variable, which you control, and the dependent variable, which is observed or measured based on the independent variable. Research Methods Knowledge Base states that hypothesis testing assumes that both mutually exclusive hypotheses research and null exhaust every possible outcome and in the end, one is accepted and the other is rejected.

However, it has a very specific meaning within academic research. Hypothesis: an idea or explanation for something that is based on known facts but has not yet been proved. For example, a hypothesis might look something like this:. The link between the two seems plausible and logical, but it is not proven at least not in a scientifically rigorous way in every possible context.

So, this qualifies as a hypothesis loosely speaking. In the world of research, however, a hypothesis needs a few more criteria to constitute a true research hypothesis or scientific hypothesis. A research hypothesis also called a scientific hypothesis is a statement about the expected outcome of a scientific study for example, a dissertation or thesis. For a hypothesis to be a genuine research hypothesis, this statement needs to have three attributes — specificity , testability and falsifiability.

As you can see, the hypothesis is very specific in that it identifies the variables involved expertise and trust , the parties involved a customer and an advisor , as well as the expected relationship type positive correlation. A hypothesis must be testable to qualify as a scientific hypothesis. Testability means that you must be able to collect observable data in a scientifically rigorous fashion to assess whether it supports the hypothesis or not. In other words, there needs to be a way to prove the claim.

Generally, one would use quantitative research methods , covering a large sample a group of people to test such a hypothesis. Hypothesis 2: There are invisible, undetectable and unobservable forces all around us that influence our likelihood to trust a financial advisor.

To be a useful hypothesis, it also needs to be falsifiable disprovable. In other words, there needs to be some identifiable way to test whether a hypothesis is false.
