Difference Between Guess And Hypothesis Statement

Key Difference: A Hypothesis is an uncertain explanation regarding a phenomenon or event. It is widely used as a base for conducting tests and the results of the tests determine the acceptance or rejection of the hypothesis. On the other hand, prediction is generally associated with the non-scientific guess. It defines the outcome of future events based on observation, experience and even a hypothesis. Hypothesis can also be defined in terms of prediction as a type of prediction which can be tested.

A Hypothesis is an uncertain explanation regarding a phenomenon or event. It is widely used as a base for conducting tests and the results of the tests determine the acceptance or rejection of the hypothesis. It can always be tested by experimentation after the formulation. It is generated by gathering possible evidence. Later, the investigation is carried out to test the hypothesis. It is either accepted or assumed.

Example of a hypothesis -

“I think that these leaves of the plant became discolored due to lack of sunlight”

In this sentence, one can easily smell a sense of guess. However, this guess is a type of educated guess. Therefore, hypothesis is also known as an educated guess. This hypothesis can be tested by various scientific methods or further investigation.

Prediction is generally used in non-scientific world to define the outcome of future events. It is also referred to as forecast and in most of the cases it is not based on any experience or knowledge.

For example, if I will buy a lottery ticket, I will win today. Now, in this example, a prediction is made regarding the future. However, it cannot be tested before its actual occurrence. Therefore, it will be termed as a prediction.

However, a scientific prediction is specially the one that is based on the hypothesis. A prediction in research evolves from a hypothesis, but they still do not guarantee the success of each other. Thus, the meaning of the prediction may vary a little depending upon the context. Generally, it depicts only a statement regarding the future. However, in scientific research it is based on the hypothesis and can be regarding any type of phenomenon.

Definition

A Hypothesis is an uncertain explanation regarding a phenomenon or event. It is widely used as a base for conducting tests and the results of the tests determine the acceptance or rejection of the hypothesis.

Prediction is generally associated with a non-scientific guess. It defines the outcome of future events based on observation, experience and even a hypothesis.

Origin

The term derived from the Greek, hypotithenai meaning "to put under" or "to suppose."

From Latin praedict- 'made known beforehand, declared'.

Proving methodology

Various experiments can lead to various results. Thus, a hypothesis can be proved or rejected depending upon the method used by the scientists.

Predictions which are based on irrational notions can be tested on the occurrence of the associated phenomenon or occurrence.

A scientific prediction is based on the hypothesis and can be tested.

Supported by Reasoning

Yes

Depends

Example

Ultra violet light may cause skin cancer.

Leaves will change color when the next season arrives.

Hypothesis vs Prediction

The terms “hypothesis” and “prediction” are often used interchangeably by some people. However, this should not be the case because the two are completely different. While a hypothesis is a guess that is predominantly used in science, a prediction is a guess that is mostly accepted out of science.

A hypothesis is otherwise known as a good or intelligent guess. It assumes the nature of the less known or even the unknown. Being described as intelligent wouldmean that hypotheses are based on a series of experiments and are grounded by facts. By using the gathered facts, a hypothesis tends to create relationships between different variables which will serve as the source of a more concrete and scientific explanation.

For example, a hypothesis can be formulated from analyzing the relationship of the learner’s study habits and the level of test anxiety experienced during an examination. It is also because of the linking of variables (dependent and independent) that often make hypotheses structurally longer than predictions.

Moreover, hypotheses are testable guesses about the things that you’d expect to take place in your research study. Aside from generating a conclusion, formulating hypotheses is another aim of experimentation.

By contrast, a prediction is much harder to define because there are many variations of predictions depending on what situation or context you’re trying to look at. Like a hypothesis, it is still another type of guess that can either be scientific or fictional (even prophetic). But because of the latter, it comes as no surprise that many associate predictions with guesses that come straight out from someone’s mind.

A person who predicts usually has little or no knowledge of the subject matter being predicted although there are some predictions that may still be based on observable facts. With fictional predictions, however, you will usually encounter guessing the possible outcomes or events. One of the popular predictions today is the prediction of the end of the days which is bound to take place late in the year 2012. This will also lead to associating predictions with self-proclaimed prophets and fortunetellers alike.

Perhaps the biggest difference between the two is the methodology of proving each of them. A prediction can actually be proven either wrong or right with the non-occurrence or occurrence of a certain event. And the story ends after that. A hypothesis is a different story because its proving methods can be done in multiple stages. This means that one scientist can disprove a hypothesis today by using his scientific system, and later on another scientist can prove that it is actually correct using another type of scientific tool.

Summary:

1.A hypothesis is a more intelligent guess.
2.Hypotheses analyze the relationships between existing variables.
3.Hypotheses are usually structured longer than predictions.
4.Predictions are often fictional which are a pure guess with no factual bases.
5.Predictions are linked to foretelling future events.
6.Predictions can be proven only once while a hypothesis can still end up as a hypothesis even if it has already been proven because another scientific inquiry might prove it contrary in the future.
