# What Are Examples of a Hypothesis? - ThoughtCo

Hypothesis testing assists in using sample data to make decisions about population parameters such as averages, standard deviations, and proportions. Testing a hypothesis using statistical methods is equivalent to making an educated guess based on the probabilities associated with being correct. When an organization makes a decision based on a statistical test of a hypothesis, it can never know for sure whether the decision is right or wrong, because of sampling variation. Regardless how many times the same population is sampled, it will never result in the same sample mean, sample standard deviation, or sample proportion. The real question is whether the differences observed are the result of changes in the population, or the result of sampling variation. Statistical tests are used because they have been designed to minimize the number of times an organization can make the wrong decision. There are two basic types of errors that can be made in a statistical test of a hypothesis:

Evolution’s Hypothesis – Small, step-wise changes over great periods of time will result in the entirety of biological diversity, including the development of animals versus plants and the different, large grouping within each of these kingdoms. (And this also includes the fungi and other kingdoms of organisms on Earth.)

CORRECTION: Scientists do strive to be unbiased as they consider different scientific ideas, but scientists are people too. They have different personal beliefs and goals  and may favor different hypotheses for different reasons. Individual scientists may not be completely objective, but science can overcome this hurdle through the action of the scientific community, which scrutinizes scientific work and helps balance biases. To learn more, visit in our section on the social side of science.

CORRECTION: Perhaps because the last step of the Scientific Method is usually "draw a conclusion," it's easy to imagine that studies that don't reach a clear conclusion must not be scientific or important. In fact, scientific studies don't reach "firm" conclusions. Scientific articles usually end with a discussion of the limitations of the tests performed and the alternative hypotheses that might account for the phenomenon. That's the nature of scientific knowledge  it's inherently tentative and could be overturned if new evidence, new interpretations, or a better explanation come along. In science, studies that carefully analyze the strengths and weaknesses of the test performed and of the different alternative explanations are particularly valuable since they encourage others to more thoroughly scrutinize the ideas and evidence and to develop new ways to test the ideas.

## Hypothesis Definition, Checklist, and Examples

Here we considers hypothesis tests to compare parameters of two populations with each other. For example, we may want to know if after a process change the process is different from the way it was before the change. The data after the change constitute one population to be compared with the data prior to change, which constitute the other population. Some specific comparative questions are: Has the process mean changed? Has the process variability reduced? If the collected data are discrete, such as defectives and nondefectives, has percent defective changed?

Intelligent Design’s Hypothesis – The large groups of organisms are differentiated by irreducibly complex structures and are thus completely distinct.

F distribution, which is a skewed distribution and is characterized by the degrees of freedom used to estimate S1 and S2, called the numerator degrees of freedom (n1 – 1) and denominator degrees of freedom (n2 – 1), respectively. Under the null hypothesis, the F statistic becomes S12/S22

Predictions – The fossil record should only include fossils of modern kinds. Hypothetical ancestors could not have existed. Anything other than the modern kinds may have once existed, but did not survive the catastrophic events like Noah’s flood.

## A hypothesis is a tentative, testable answer to a scientific question

Creation Sciences’s Hypothesis – The Earth is only 6000 years old. While microevolution may yet be possible, the major groups (kinds) of organisms were placed on the Earth at its formation 6000 years ago.

If the computed t exceeds the critical t, the null hypothesis is rejected.
Example. The following data were obtained on the life of light bulbs made by two manufacturers:

## What is a Hypothesis? (with pictures) - wiseGEEK

When testing a claim about a population proportion, with a fixed number of independent trials having constant probabilities, and each trial has two outcome possibilities (a binomial experiment), a p test can be used. When np
If conditions that np ≠ 5 and n(1-p)≠5 are met, then the binomial distribution of sample proportions can be approximated by a normal distribution. The hypothesis tests for comparing a sample proportion, p, with a fixed value, po, are given by the following:
