The decision rule in this case states that 'for a fixed significance value α, a sequence fails the statistical test if it's P value<α'.

EURASIP Journal on Wireless Communications and Networking

The general perception is that, to achieve a fixed significance level and power, a group sequential test will require a larger maximum total sample size than required by the corresponding standard single-stage test because missing observations are possible under the group sequential test setting.

Statistics & Probability Letters

As expected, power increases with increasing sample size with a fixed significance level.

Plosone

As expected, power increase with increasing sample size for a fixed significance level.

Plosone

Figure 4 shows the sample size under different views of effect size with fixed significance level at 0.05.

Plosone

In a clinical study, when the interest is to target the power for different effect sizes, sample size can be estimated to ensure that the endpoint with the smallest effect size is sufficiently powered with a fixed significance level <img src="http://journals.plos.org/plosone/article/asset?id=info?doi/10.1371/journal.pone.0005054.e018.PNG" class= inline-graphic"/>.

Expert writing Tips

Best practice

When using "fixed significance", clearly define the context and criteria used to establish the level of significance to avoid ambiguity.

Common error

Don't assume that "fixed significance" implies absolute certainty. It indicates a predetermined threshold for statistical significance, not a guarantee of the truth or practical importance of the findings.

Linguistic Context

The phrase "fixed significance" functions as a descriptor specifying that a particular level of statistical significance has been predetermined and will not be altered throughout a study or analysis. Ludwig confirms its usability in written English.

Ludwig's WRAP-UP

The phrase "fixed significance" is a technical term primarily used within scientific and academic research to describe a predetermined threshold for statistical significance. Ludwig confirms that the phrase is correct and usable in written English. Its purpose is to maintain objectivity and prevent bias in data analysis. Although not a highly frequent term, its usage is consistent and important within its specific context. Alternative phrasing might include "constant significance" or "established significance", but the key is to clearly communicate that the significance level was set prior to analysis.

More alternative expressions

Phrases that express similar concepts, ordered by semantic similarity:

constant significance

Emphasizes the unchanging nature of the significance.

stable significance

Indicates the reliability and consistency of the significance.

unchanging significance

Directly states that the significance remains the same.

established significance

Highlights that the significance has been previously determined.

predefined significance

Focuses on the fact that the significance was set beforehand.

predetermined significance

Like predefined, but emphasizes the decision-making aspect.

set significance

Similar to predefined, but with a slightly more active connotation.

specified significance

Highlights that the significance was explicitly defined.

FAQs

How is "fixed significance" used in research?

In research, "fixed significance" refers to a predetermined threshold (alpha level) used to determine whether the results of a study are statistically significant. If the p-value is below this threshold, the results are considered significant.

What does it mean to have a "fixed significance" level of 0.05?

A "fixed significance" level of 0.05 means there's a 5% risk of concluding that a significant difference exists when there is actually no real difference (Type I error). It's a common but arbitrary threshold in statistical hypothesis testing.

What are some alternatives to "fixed significance"?

Alternatives to "fixed significance" include phrases like "constant significance", "established significance", or "predetermined significance", which emphasize different aspects of the concept.

Why is it important to choose a "fixed significance" level before conducting a study?

Choosing a "fixed significance" level beforehand helps to minimize bias and ensures that the statistical analysis is conducted in a consistent and objective manner. It prevents researchers from adjusting the significance level after seeing the results to achieve a desired outcome.
