I think you are asking: What is hypothesis testing in the field of statistics. See: http://en.wikipedia.org/wiki/Statistical_hypothesis_testing

1 answer


The q-value formula in statistical hypothesis testing is used to calculate the false discovery rate of a set of hypothesis tests. It helps determine the likelihood of falsely rejecting a true null hypothesis.

1 answer


A hypothesis is the first step in running a statistical test (t-test, chi-square test, etc.)

A NULL HYPOTHESIS is the probability that what you are testing does NOT occur.

An ALTERNATIVE HYPOTHESIS is the probability that what you are testing DOES occur.

A non-directional research hypothesis is a kind of hypothesis that is used in testing statistical significance. It states that there is no difference between variables.

Make objective decisions about the validity of the hypotheses.

A statistical hypothesis test will usually be performed by inductively comparing results of experiments or observations. The number or amount of comparisons will generally dictate the statistical test to use. The researcher is basically making a statement and assuming that it is either correct (the hypothesis - H1) or assuming that it is incorrect (the null hypothesis - H0) and testing that assumption within a predetermined significance level - the alpha.

A hypothesis must be subjected to rigorous testing before it becomes a theory. A hypothesis is used to explain some phenomenon about the natural world. Once a hypothesis has been created, it can be used to formulate predictions. These predictions in turn are then tested to be accurate through experimentation or observation.

A hypothesis is composed of two parts: the null hypothesis, which states that there is no effect or no difference between groups, and the alternative hypothesis, which states that there is an effect or a difference. These two components together form the basis for statistical testing and inference in research.

A test of a statistical hypothesis is a two-action decision problem after the experimental sample values have been obtained, the two-actions being the acceptance or rejection of the hypothesis under consideration.

To formulate a hypothesis effectively using hypothesis testing, one must first identify a research question and make a clear statement about the relationship between variables. Then, the hypothesis should be specific, testable, and based on existing knowledge or theory. Finally, the hypothesis should be framed in a way that allows for statistical analysis to determine its validity.

1 answer


The purpose of hypothesis testing is to determine whether there is enough statistical evidence in a sample of data to support or reject a specific claim about a population parameter. It involves formulating a null hypothesis (which represents no effect or no difference) and an alternative hypothesis (which represents an effect or difference), then using sample data to assess the likelihood of observing the data if the null hypothesis were true. By calculating a p-value and comparing it to a predetermined significance level, researchers can make informed decisions regarding the validity of the hypotheses. Ultimately, hypothesis testing aids in drawing conclusions from data and making informed decisions based on statistical evidence.

In statistical hypothesis testing you have a null hypothesis against which you are testing an alternative. The hypothesis concerns one or more characteristics of the distribution.

It is easier to illustrate the idea of directional and non-directional hypothesis. In studying the academic abilities of boys and girls the null hypothesis would be that boys and girls are equally able. One directional hypothesis would be that boys are more able. The non-directional alternative would be that there is a gender difference. You have no idea whether boys are more able or girls - only that they are not the same.

1 answer


No. The null hypothesis is not considered correct. It is an assumption, and hypothesis testing is a consistent meand of determining whether the data is sufficiently strong to say that it may be untrue. The data either supports the alternative hypothesis or it fails to reject it. See examples in links. Also note this quote from Wikipedia: "Statistical hypothesis testing is used to make a decision about whether the data contradicts the null hypothesis: this is called significance testing. A null hypothesis is never proven by such methods, as the absence of evidence against the null hypothesis does not establish it."

The difference between the null hypothesis and the alternative hypothesis are on the sense of the tests. In statistical inference, the null hypothesis should be in a positive sense such in a sense, you are testing a hypothesis you are probably sure of. In other words, the null hypothesis must be the hypothesis you are almost sure of. Just an important note, that when you are doing a tests, you are testing if a certain event probably occurs at certain level of significance. The alternative hypothesis is the opposite one.

forming a hypothesis is when you come up with an educated guess.. what you think it may be .

testing a hypothesis is when you're testing to see if someone else's guess is right.

1 answer


Concluding that the hypothesis is correct based on personal beliefs or opinions is not part of testing a hypothesis. Testing a hypothesis involves designing experiments, collecting data, and analyzing results to determine if the hypothesis is supported or not.

1 answer


When you formulate and test a statistical hypothesis, you compute a test statistic (a numerical value using a formula depending on the test). If the test statistic falls in the critical region, it leads us to reject our hypothesis. If it does not fall in the critical region, we do not reject our hypothesis. The critical region is a numerical interval.

A hypothesis statement consists of three parts: the null hypothesis (H0), the alternative hypothesis (Ha), and the level of significance (alpha). The null hypothesis states that there is no relationship or difference between variables, while the alternative hypothesis suggests the presence of a relationship or difference. The level of significance determines the threshold for accepting or rejecting the null hypothesis based on statistical testing.

Qualitative methods focus on exploring phenomena in-depth and are not structured to systematically test hypotheses. They primarily aim to gain insights, understand experiences, and generate theories rather than test specific hypotheses with statistical rigor. Quantitative methods are better suited for hypothesis testing as they involve data collection and analysis that allow for hypothesis validation or rejection.

1 answer


A hypothesis is a suggestion of a way to explain something. If the hypothesis is tested and confirmed, it can advance to the status of theory. The conclusion of testing a hypothesis will be either that the hypothesis is confirmed, or it is not confirmed.

A statistical hypothesis is anything that can be tested against observations. So the hypothesis can be that you can remember two numbers.

Hypothesis testing helps us make decisions about the validity of a claim or hypothesis based on statistical evidence. By comparing observed data against a null hypothesis, we can determine whether to reject or fail to reject that hypothesis. This process aids in making informed conclusions about relationships or differences within data, guiding decisions in fields like science, business, and healthcare. Ultimately, it allows us to quantify uncertainty and assess the likelihood of outcomes based on sample data.

Bracketing method involves setting upper and lower bounds for estimating a parameter, while statistical value refers to a calculated number that helps make decisions in hypothesis testing. The bracketing method helps narrow down the range of possible values, whereas statistical values provide a measure of significance or strength of evidence in statistical analysis.
