## What does it mean if your results are statistically significant?

Statistical Significance Definition A result of an experiment is said to have statistical significance, or be statistically significant, if it is likely not caused by chance for a given statistical significance level.

…

It also means that there is a 5% chance that you could be wrong..

## How do you know if research is statistically significant?

A study is statistically significant if the p-value is less than the pre-specified alpha. Stated succinctly: A p-value less than alpha is a statistically significant result. A p-value greater to or equal to alpha is not a statistically significant result.

## What do you mean by significant?

1 : having meaning especially : suggestive a significant glance. 2a : having or likely to have influence or effect : important a significant piece of legislation also : of a noticeably or measurably large amount a significant number of layoffs producing significant profits.

## How do you say something is statistically significant?

A data set provides statistical significance when the p-value is sufficiently small. When the p-value is large, then the results in the data are explainable by chance alone, and the data are deemed consistent with (while not proving) the null hypothesis.

## How do you tell the difference between statistical significance and practical significance?

Practical Significance Size matters! While statistical significance relates to whether an effect exists, practical significance refers to the magnitude of the effect. However, no statistical test can tell you whether the effect is large enough to be important in your field of study.

## What does it mean that the results are not statistically significant for this study?

This means that the results are considered to be „statistically non-significant‟ if the analysis shows that differences as large as (or larger than) the observed difference would be expected to occur by chance more than one out of twenty times (p > 0.05).

## What does statistically significant difference mean?

A statistically significant difference is simply one where the measurement system (including sample size, measurement scale, etc.) was capable of detecting a difference (with a defined level of reliability). Just because a difference is detectable, doesn’t make it important, or unlikely.

## How do you know if results are significant?

There are three major ways of determining statistical significance: If you run an experiment and your p-value is less than your alpha (significance) level, your test is statistically significant.

## How do you tell if there is a significant difference between two groups?

Usually, statistical significance is determined by calculating the probability of error (p value) by the t ratio. The difference between two groups (such as an experiment vs. control group) is judged to be statistically significant when p = 0.05 or less.

## What is the most common standard for statistical significance?

Significance levels show you how likely a pattern in your data is due to chance. The most common level, used to mean something is good enough to be believed, is . 95. This means that the finding has a 95% chance of being true.

## What does P value signify?

The P value, or calculated probability, is the probability of finding the observed, or more extreme, results when the null hypothesis (H 0) of a study question is true – the definition of ‘extreme’ depends on how the hypothesis is being tested.

## What is statistical significance and why is it important?

“Statistical significance helps quantify whether a result is likely due to chance or to some factor of interest,” says Redman. When a finding is significant, it simply means you can feel confident that’s it real, not that you just got lucky (or unlucky) in choosing the sample.

## How do you explain significant difference?

In principle, a statistically significant result (usually a difference) is a result that’s not attributed to chance. More technically, it means that if the Null Hypothesis is true (which means there really is no difference), there’s a low probability of getting a result that large or larger.

## What do you do when results are not statistically significant?

When the results of a study are not statistically significant, a post hoc statistical power and sample size analysis can sometimes demonstrate that the study was sensitive enough to detect an important clinical effect. However, the best method is to use power and sample size calculations during the planning of a study.

## How do you explain significance?

Significance means having the quality of being “significant” — meaningful, important. It also refers to the meaning of something. A certain date might have significance because it’s your birthday or the anniversary of Princess Di’s wedding. Significance starts with the word sign for a reason.
