What is it called when scientists state shearer their data confirmed or rejected the hypothesis?
When scientists state that their data confirmed or rejected a hypothesis, it is typically referred to as "hypothesis testing." This process involves analyzing the collected data to determine whether it supports or contradicts the proposed hypothesis. The outcome can lead to the acceptance or rejection of the hypothesis, contributing to the scientific understanding of the phenomenon being studied.
Why is it not a bad thing if your hypothesis is rejected?
If your hypothesis is rejected, it means that your experiment revealed valuable information. It allows you to refine your understanding of the topic and design new experiments. In science, rejection of hypotheses is essential for progress and leads to a deeper understanding of the phenomena being studied.
What rules does a hypothesis have to follow?
"A hypothesis is a proposed answer to a question. To answer the question raised by your observations, the hypothesis must be testable." it means that you need to be able to prove that your hypothesis is true or not by creating an experiment and collect/analyze the data
What is the most important thing about a hypothesis?
The most important thing about a hypothesis is that it is testable and falsifiable. This means that the hypothesis can be supported or rejected based on evidence gathered from experiments or observations.
How is null hypothesis tested?
A null hypothesis states that there is no relationship between two or more variables being studied. The assumption in science is that the null hypothesis is true until sufficient evidence emerges, though statistical testing, to reject the null and support an alternative hypothesis. The exact statistical test depends on the number and type of variables being tested, but all statistical hypothesis tests result in a probability value (p). Generally, the null is rejected when p < .05 representing less than a 5% chance that the relationship between the variables is due to error. This cutoff - called alpha - can be set lower in certain fields or studies, but rarely is set higher.
What is the meaning of null hypthesis being rejected?
You may want to prove that a given statistic of a population has a given value. This is the null hypothesis. For this you take a sample from the population and measure the statistic of the sample. If the result has a small probability of being (say p = .025) if the null hypothesis is correct, then the null hypothesis is rejected (for p = .025) in favor of an alternative hypothesis. This can be simply that the null hypothesis is incorrect.
What is Rejected Hypothesis?
It is when you know that your hypothesis is wrong.
What causes a hypothesis to be rejected?
A hypothesis will be rejected if it fails the necessary testing required for it to become a scientific theory.
What is the meaning of a null hypnosis being rejected?
A null hypothesis being rejected means that statistical analysis has provided sufficient evidence to conclude that there is a significant effect or relationship present in the data, contrary to the null hypothesis, which typically posits no effect or relationship. This rejection suggests that the observed results are unlikely to have occurred by random chance alone. In practical terms, this often leads researchers to accept an alternative hypothesis that proposes a specific effect or relationship exists.
Why can an accepted hypothesis be rejected at a later date?
The answer to the question why is this: It can be rejected at a later date because it is falsifiable in nature if it is a good hypothesis. If you meant to ask HOW it can be rejected, the answer is by way of further experimentation that rules out some or all of the hypothesis as stated.

What do you call the statement that determines if the null hypothesis is rejected?
The hypothesis test.
Are hypothesis often rejected?
no. you need to have solid proof that it exist.. else it will be rejected.
Should flemings hypothesis be supported or rejected based on the experiment?
To determine whether Fleming's hypothesis should be supported or rejected based on an experiment, one would need to analyze the results of the experiment in relation to the hypothesis. If the data from the experiment aligns with the predictions made by Fleming's hypothesis, then it should be supported. However, if the results contradict the hypothesis, it may need to be rejected or revised.
How is H1 hypothesis rejected?
H1 hypothesis is rejected when the p-value associated with the test statistic is less than the significance level (usually 0.05) chosen for the hypothesis test. This indicates that the data provides enough evidence to reject the alternative hypothesis in favor of the null hypothesis.
What is the difference between a Type I error and a Type II error in hypothesis testing?
In hypothesis testing, a Type I error occurs when a true null hypothesis is incorrectly rejected, while a Type II error occurs when a false null hypothesis is not rejected.
Can hypothesis be supported or rejected by through experimentation?
yes
