CoRelation of hypothesis in psychology?
In statistics, a null hypothesis (H0) is a hypothesis set up to be nullified or refuted in order to support an alternative hypothesis. When used, the null hypothesis is presumed true until statistical evidence, in the form of a hypothesis test, indicates otherwise - that is, when the researcher has a certain degree of confidence, usually 95% to 99%, that the data does not support the null hypothesis. It is possible for an experiment to fail to reject the null hypothesis. It is also possible that both the null hypothesis and the alternate hypothesis are rejected if there are more than those two possibilities.
What are the examples of hypothesis?
A hypothesis is like an educated guess before an experiment is conducted. For example, when boiling water, it would be possible to hypothesize that the higher the temperature, the faster the water will boil.
What are the sources of Hypothesis?
There are infinite sources of potential hypotheses. Usually one begins with an empirically-verifiable proposition or statement from a theory and formalises it into a hypothesis for testing. For example: Theory - (Marx) all of history is driven by class-conflict fermenting into revolutions. Hypothesis - all else equal, we would expect there to be many revolutions in history.
What is a causal hypothesis?
A casual hypothesis is a more usual hypothesis.
What is the difference between hypothesis and experimentation?
A hypothesis is a guess of what the outcome of the experiment is. An experimentation is where you test that hypothesis.
What causes hypothesis to be rejected?
We have two types of hypothesis i.e., Null Hypothesis and Alternative Hypothesis. we take null hypothesis as the same statement given in the problem. Alternative hypothesis is the statement that is complementary to null hypothesis. When our calculated value is less than the tabulated value, we accept null hypothesis otherwise we reject null hypothesis.
when the null hypothesis is greater than 0.005?

What is null hypothesis in negatively stated in hypothesis formulated?
a negatively stated hypothesis. example: the application of horse manure has no significant effect!
Explain what is meant by null hypothesis?
The null hypothesis is an hypothesis about some population parameter. The goal of hypothesis testing is to check the viability of the null hypothesis in the light of experimental data. Based on the data, the null hypothesis either will or will not be rejected as a viable possibility.
If we reject the null hypothesis what can we conclude about the alpha risk?
If we reject the null hypothesis, we conclude that the alternative hypothesis which is the alpha risk is true. The null hypothesis is used in statistics.
What does the researcher hope to do with null hypothesis the opposite of the research hypothesis?
Be able to reject the null hypothesis and accept the research hypothesis

What is a null hypothesis?
The null hypothesis is the statement that there is no relationship between two observations.
When you accept the Null Hypothesis you are certain that the Null Hypothesis is correct?
No, you are never certain.
How do you write a null hypothesis in notation?
A null hypothesis is written in notation by using a a statement that is the opposite of what is intended to be found, for example the research will derive answers or needed statements that is different from what is intended.
What is another name for the probability of observing a sample value at least as extreme as a given on under a null hypothesis?
The significance level of the observation - under the null hypothesis. The significance level of the observation - under the null hypothesis. The significance level of the observation - under the null hypothesis. The significance level of the observation - under the null hypothesis.
