Jun 01, 2017 · The main statistical significance associated with results obtained in a medical research means that from a statistical perspective, the obtained study results were not due to chances. It is to mean that a replication of the results will produce lower critical values.
What does it mean if your test results is statistically significant? Answer: It is unlikely that the results occurred by chance alone
In other words, what does it mean to say that results are statistically significant? Be sure to explain what a p value is and how it relates to statistical significance. As a reminder, M stands for mean, SD stands for standard deviation, the t indicates that this was a t …
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.Oct 21, 2014
If a result is statistically significant, that means it's unlikely to be explained solely by chance or random factors. In other words, a statistically significant result has a very low chance of occurring if there were no true effect in a research study.Jan 7, 2021
Statistical significance means that the result observed in a sample is unusual when the null hypothesis is assumed to be true. When testing a hypothesis using the P-value Approach, if the P-value is large, reject the null hypothesis.
If the computed t-score equals or exceeds the value of t indicated in the table, then the researcher can conclude that there is a statistically significant probability that the relationship between the two variables exists and is not due to chance, and reject the null hypothesis.
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 it mean when a test is statistically significant? it has reached alpha level status. the test statistic had a P-value higher than the alpha level. the test statistic had a P-value lower than the alpha level. it is important in practical terms.
If the result is not statistically significant and the sample size is small, the result is inconclusive. If the result is not statistically significant and the sample size is large, the research hypothesis is likely false.
So if your sample size is big enough you can say that a t value is significant if the absolute t value is higher or equal to 1.96, meaning |t|≥1.96.Dec 11, 2016
Statistical significance is important because it allows researchers to hold a degree of confidence that their findings are real, reliable, and not due to chance.
A statistically significant relationship is one that is large enough to be unlikely to have occurred in the sample if there's no relationship in the population. The issue of whether a result is unlikely to happen by chance is an important one in establishing cause-and-effect relationships from experimental data.
