What is a 'Null Hypothesis' What is a 'Null Hypothesis'.

The null hypothesis attempts to show that no variation exists between variables or that a single variable is no different than its mean.

What is a Hypothesis? - Definition & Explanation The Purpose of a Hypothesis. A hypothesis is used in an experiment to define the relationship between two variables. The purpose of a hypothesis is to find the answer to a question. A formalized hypothesis will force us to think about what results we should look for in an experiment.

- Hypothesis means an educated guess about the outcome of an experiment. For example, if you were to perform an experiment about how fast water boils depending on different temp … eratures your hypothesis may be the higher the temperature used, the faster the water will boil. 14 people found this useful.

Hypothesis Testing A statistical hypothesis is an assumption about a population parameter. This assumption may or may not be true. Hypothesis testing refers to the formal procedures used by statisticians to accept or reject statistical hypotheses. The best way to determine whether a statistical hypothesis is true would be to examine the entire population.

Which of These Statements Is True Regarding Scientific Theories? A hypothesis is a question or an idea that a scientist tries to answer by performing an experiment. If the data derived from the experiment is compelling enough, the hypothesis becomes a theory. Scientists accept theories as adequate explanations for phenomena. This is in stark contrast to the use of the word theory in a non-scientific sense.

The first step of a psychological investigation is to identify an area of interest and develop a hypothesis that can then be tested. While a hypothesis is often described as a hunch or a guess, it is actually much more specific. A hypothesis can be defined as an educated guess about the relationship between two or more variables. For example, a researcher might be interested in the relationship between study habits and test anxiety.

Hypothesis In statistical hypothesis testing, two hypotheses are compared. These are called the null hypothesis and the alternative hypothesis. The null hypothesis is the hypothesis that states that there is no relation between the phenomena whose relation is under investigation, or at least not of the form given by the alternative hypothesis. The alternative hypothesis, as the name suggests, is the alternative to the null hypothesis: it states that there is some kind
