The Difference Between Hypothesis and Theory

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.

In the scientific method, the hypothesis is constructed before any applicable research has been done, apart from a basic background review. You ask a question, read up on what has been studied before, and then form a hypothesis.

A hypothesis is usually tentative; it's an assumption or suggestion made strictly for the objective of being tested.

A theory , in contrast, is a principle that has been formed as an attempt to explain things that have already been substantiated by data. It is used in the names of a number of principles accepted in the scientific community, such as the Big Bang Theory . Because of the rigors of experimentation and control, it is understood to be more likely to be true than a hypothesis is.

In non-scientific use, however, hypothesis and theory are often used interchangeably to mean simply an idea, speculation, or hunch, with theory being the more common choice.

Since this casual use does away with the distinctions upheld by the scientific community, hypothesis and theory are prone to being wrongly interpreted even when they are encountered in scientific contexts—or at least, contexts that allude to scientific study without making the critical distinction that scientists employ when weighing hypotheses and theories.

The most common occurrence is when theory is interpreted—and sometimes even gleefully seized upon—to mean something having less truth value than other scientific principles. (The word law applies to principles so firmly established that they are almost never questioned, such as the law of gravity.)

This mistake is one of projection: since we use theory in general to mean something lightly speculated, then it's implied that scientists must be talking about the same level of uncertainty when they use theory to refer to their well-tested and reasoned principles.

The distinction has come to the forefront particularly on occasions when the content of science curricula in schools has been challenged—notably, when a school board in Georgia put stickers on textbooks stating that evolution was "a theory, not a fact, regarding the origin of living things." As Kenneth R. Miller, a cell biologist at Brown University, has said , a theory "doesn’t mean a hunch or a guess. A theory is a system of explanations that ties together a whole bunch of facts. It not only explains those facts, but predicts what you ought to find from other observations and experiments.”

While theories are never completely infallible, they form the basis of scientific reasoning because, as Miller said "to the best of our ability, we’ve tested them, and they’ve held up."

• proposition
• supposition

hypothesis , theory , law mean a formula derived by inference from scientific data that explains a principle operating in nature.

hypothesis implies insufficient evidence to provide more than a tentative explanation.

theory implies a greater range of evidence and greater likelihood of truth.

law implies a statement of order and relation in nature that has been found to be invariable under the same conditions.

"What's the plural of hypothesis?"

The plural of hypothesis is hypotheses .

Definition of hypothesis:

A supposition or assumption based on limited evidence which has yet to be proven or disproven.

Is 'Hypothesis' Plural or Singular?

The plural form of "hypothesis" is "hypotheses." This is because "hypothesis" is a Greek-derived word that follows the rules for forming plurals of Greek-derived words.

In general, Greek-derived words that end in "-is" form the plural by changing the ending to "-es."

The plural of "hypothesis" is "hypotheses" because it is a borrowed word from the Greek language, and it follows the rules of Greek grammar for forming the plural.

In Greek, the plural of "hupothesis," the Greek word from which "hypothesis" is derived, is "hupotheses."

Other examples of Greek-derived words that follow this pattern include "analysis" (singular) and "analyses" (plural), "crisis" (singular) and "crises" (plural), and "thesis" (singular) and "theses" (plural).

The word "hypothesis" comes from the Greek word "hypothesis," which means "base," "foundation," or "assumption."

In scientific contexts, hypotheses are educated guesses or proposed explanations for a phenomenon that is based on limited evidence and is used as a starting point for further investigation.

Plural of Hypothesis Example Sentences

Here are some examples to illustrate the difference between the singular and plural forms of the word "hypothesis":

Singular: " A hypothesis has been proposed to explain the sudden increase in the number of earthquakes in the region" .

Plural: " Two hypotheses have been proposed to explain the sudden increase in the number of earthquakes in the region. One suggests that the earthquakes are caused by tectonic activity, while the other suggests that they are caused by the injection of wastewater into the ground" .

Singular: " The hypothesis that the Earth is flat has been debunked by scientific evidence" .

Plural: " There are many hypotheses about the origins of the universe, but the most widely accepted one is the Big Bang theory" .

Throughout history multiple hypotheses were put forward to explain why objects tended to fall to Earth when dropped. The Greeks believed it was because the Earth was the center of the Universe.

What Is The Definition Of Hypothesis

As found in the Meriam Webster Dictionary 

• An assumption or concession made for the sake of argument
• an interpretation of a practical situation or condition taken as the ground for action
• a tentative assumption made in order to draw out and test its logical or empirical consequences
• the antecedent clause of a conditional statement

As found in the Cambridge Dictionary

• an idea or explanation for something that is based on known facts but has not yet been proved: several hypotheses for global warming have been suggested.

In “The Origin of Hypothesis” it is phrased as a ‘scientific guess’. In the context of science, a hypothesis is a placeholder for a theory until it is proven by science to be accurate.

A scientific hypothesis sed to explain something occurring in our universe that currently does not fit into our current available scientific theories. Scientific hypotheses also include null hypothesis, working hypothesis, and alternative hypothesis. 

History and Origin of The Word

From the Greek hypotithenai to put under, suppose, from hypo- + tithenai to put. The first use of the word hypothesis can be traced back to 1596. Issac Newton actually rejected the hypothesis, he said “Hypotheses non fingo” which translates to “I Frame no hypotheses”. This was back in 1721 in Issac Newton’s book “Opticks, or A Treatise of the Reflections, Refractions, Inflections, and Colours of Light”

What Is More Than One Hypothesis Called?

The plural form of the hypothesis is hypotheses. This is the only way in the English language to make hypothesis plural. Because of the Greek origin, the rule of making a noun that ends in “is” to change it to “es.”

• Assumption – Something taken for granted
• Postulate- suggest or assume the existence, fact, or truth of (something) as a basis for reasoning, discussion, or belief
• Rationale – Logic for belief, action
• Previous observations- things that were seen or experienced in the past
• Supposition – guess, belief
• Theorem – explanation based on hypothesis and experiments done by experimenters using the scientific method
• Thesis – belief, assumption to be tested
• Conjecture – speculation, assumption
• Conclusion – end
• Tentative Explanation – clarification; reason
• Guess – belief, speculation 
• Interpretation – understanding
• Premise – hypothesis, argument

What Is The Difference Between Hypothesis and Theory?

Since we now know that a hypothesis is a guess or assumption, how is that different from a theory? The definition of a theory is “a supposition or system of ideas intended to explain something, especially one based on general principles independent of the thing to be explained”. 

Although we might think of a theory as something that has not been 100% proven, its definition in the application of science is something that has been tested as an explanation for things occurring. It is still an explanation that is thought of as true until proven otherwise, the difference here is that a hypothesis is thought to explain something not yet tested and could also be thought of as an unproved theory or suggested explanation.

Follow these examples to see the difference in action:

• Fact: “The clouds are dark outside.” 
• Hypothesis: “It might storm today.”
• Theory: “Rain clouds are dark because of their particulate density. The denser the water droplets are in the cloud the more light will be scattered, which will lead to a darker appearance.”
• Fact: “Light roast coffee has more caffeine than dark roast coffee”
• Hypothesis: “I should drink a cup of light roast coffee if I want more caffeine”
• Theory: “During the roasting process caffeine is slowly burned off, therefore it is true that light roast coffee has more caffeine. You should however choose dark roast if you want more caffeine per cup because although per bean light roast has more caffeine, per gram of coffee dark roast contains more caffeine. This is because you have to consider the percent of weight loss that occurs with roasting a coffee to a dark level, which is higher than the percent of caffeine lost, therefore you have more caffeine per gram in dark roast over light roast, only by a minuscule amount.”

What Is The Difference Between An Idea and Hypothesis?

Since a hypothesis is an idea that can be tested, here are some examples of what is just an idea and can’t be tested followed by a similar idea that can be tested and is a hypothesis.

• Idea: Biden would be a better president vs Trump – Can not be tested since we have no data. 
• Hypothesis: Obama did a better job at fixing unemployment vs Bush – can be tested by looking at the data.
• Idea: I could have been the best disc golfer if I started playing when I was a kid – Impossible to test
• Hypothesis: Paul McBeth probably hit more circle 2 putts on tour last year than Ricky Wysocki. – Can be proven by looking at the data for all their putts on the PDGA tour last year.

Example Sentences In Context

The following are examples of hypothesis in context:

“We came up with the assumptions and then narrowed them down to one hypothesis for each category.” – Forbes

“The notion of hypothesis testing has recently invaded the practice of entrepreneurship as a tool to construct of new ventures” – Forbes

“There’s not one unifying hypothesis as to why, but there’s probably five to 20 different things that have contributed to it.” – USA Today

“Most thinkers or hypothesists of any degree of sobriety allow, that an hypothesis…is not to be received as probably true because it accounts for all the known phenomena since this is a condition sometimes fulfilled tolerably well by two conflicting hypotheses…while there are probably a thousand more which are equally possible, but which, for want of anything analogous in our experience, our minds are unfitted to conceive” – Underdetermination of Scientific Theory

“The expensive tissue hypothesis was focused on human brains and it was never intended as a one-size-fits-all possible explanation that applied across all mammals. The original paper even said that “the cost of the additional brain tissue could have been met by strategies other than a reduction in gut size.” – National Geographic

Lots of people confuse the plural of hypothesis , and it’s not tough to see why: hypothesis is an irregular plural noun form that omits the -s/-es of regular plural nouns .

[But t]he word " hypothesis " should be used, in science, exclusively for a reasoned, sensible, knowledge-informed explanation for why some phenomenon exists or occurs. An hypothesis can be as yet untested; can have already been tested; may have been falsified; may have not yet been falsified, although tested; or may have been tested in a myriad of ways countless times without being falsified; and it may come to be universally accepted by the scientific community. An understanding of the word " hypothesis ," as used in science, requires a grasp of the principles underlying Occam's Razor and Karl Popper's thought in regard to " falsifiability "—including the notion that any respectable scientific hypothesis must, in principle, be "capable of" being proven wrong (if it should, in fact, just happen to be wrong), but none can ever be proved to be true. One aspect of a proper understanding of the word " hypothesis ," as used in science, is that only a vanishingly small percentage of hypotheses could ever potentially become a theory.

Defining the Word “Hypothesis” The term hypothesis originates from the Greek word meaning base or foundation . It is commonly understood as a starting point for scientific inquiry, a proposed explanation made on the basis of limited evidence as a starting point for further investigation. In its essence, a hypothesis is a tentative assumption designed to test its logical or empirical consequences. In scientific reasoning, a hypothesis serves as a provisional idea whose merit requires evaluation. It is not just a wild guess, but an informed conjecture that sets the stage for experimentation and observation. Key Attributes of a Hypothesis: Conjectural : A hypothesis is an educated guess about the relationship between two or more variables. Testable : It must be possible to prove that the hypothesis is true or false through evidence. Predictive : A hypothesis should make predictions that can be verified through testing. Falsifiable : To be scientific, a hypothesis must be structured in a way that it can be refuted by evidence. Hypothesis in Conditional Statements: Part of Conditional Statement Role of Hypothesis Antecedent (If clause) Contains the hypothesis Consequent (Then clause) Outcome or prediction For example, in the statement “If molecules are exposed to higher temperatures, then their kinetic energy will increase,” the hypothesis is that higher temperatures affect molecular kinetic energy.

A hypothesis must be falsifiable ; that is, it must be phrased in a way that makes it possible to reject if it is not true. Avoid complex jargon when constructing a hypothesis; clarity ensures that others can understand and test it.

Origin of the Word “Hypothesis” Ancient Greek is the initial source of the word “hypothesis.” Specifically, it derives from two Greek words: “ὑπό” meaning ‘under,’ and “θέσις” meaning ‘a placing’ or ‘proposition.’ The combination of these elements resulted in “ὑπόθεσις” (hypothesis), signifying ‘a placing under’ or ‘foundation’. Greek Origin Meaning ὑπό (hypo) below, under θέσις (thesis) placing, setting Transitioning into Late Latin , the term “ hypothesis ” maintained its original Greek meaning. By the time it reached the Middle French , as “hypothese,” it was already well-incorporated into the lexicon of scientific and philosophical discourse. Language Evolution Form Late Latin hypothesis Middle French hypothese In English, “hypothesis” retains the essence of its Greek origins: a proposed explanation for a phenomenon, a foundation for further investigation, or a premise to be tested. Key Developments : Integral to scientific method Used academically to propose theories To construct the plural form of “hypothesis,” English follows a standard pattern seen with words ending in ‘-is.’ Singular: hypothesis Plural: hypotheses Usage in English implies not just a simple carrying over of a term, but an adaptation of the concept it represents — underpinning the advancement of knowledge, it supports theoretical frameworks and empirical research.
