A level of significance of 0.05 indicates that there is a 5% risk of rejecting the null hypothesis when it is actually true, commonly referred to as a Type I error. In hypothesis testing, it establishes a threshold for determining whether the observed data is statistically significant. If the p-value obtained from the test is less than or equal to 0.05, the null hypothesis is typically rejected in favor of the alternative hypothesis. This level is widely used in scientific research to balance the risk of errors with the need for robust conclusions.
What else can I help you with?
How can you explain the significance level of at statistics?
Significance Level (Alpha Level): If the level is set a .05, it means the statistician is acknowledging that there is a 5% chance the results of the findings will lead them to an incorrect conclusion.
How many standard deviations above or below the mean should a score be to establish significance?
It depends on the significance level required. And that, in turn, will depend on the cost of making the wrong decision. For ordinary use, a 95% significance level will require 1.96 sd
What is the p-value if 0.01 is the level of significance and the mean is 18688 and the standard deviation is 15500?
In order to solve this you need the null hypothesis value also level of significance only helps you decide whether or not to reject the null hypothesis, is the p-value is above this then you do not reject the null hypothesis, if it is below you reject the null hypothesis Level of significance has nothing to do with the math
What is another name for the probability of observing a sample value at least as extreme as a given on under a null hypothesis?
The significance level of the observation - under the null hypothesis. The significance level of the observation - under the null hypothesis. The significance level of the observation - under the null hypothesis. The significance level of the observation - under the null hypothesis.
The level of significance is the maximum allowable of what?
Type I error.

Why is the sample standard deviation used to derive the standard error of the mean?
the sample mean is used to derive the significance level.
What and who determines the alpha level in statistics?
Before conducting a significance test, the statistician will choose an alpha level. Depending upon the severity of having type I or type II error, the statistician will make the alpha level higher or lower. Generally in courts, the alpha level is .05. The other common alpha levels for significance tests are .10 and .01.

Are all scientific hypotheses tested at 1 level of significance?
No, not all scientific hypotheses which are tested at level 1 are of significance.
.05 and .1 level of significance?
Another way to say it would be how important is it to be so precice to the n'th degree when what you are doing is not that complicated. Example: Add in bowl and mix - one cup flour - two eggs - 1 teaspoon cinnamon - milk (267.845 milliliters) The milk is past insignificant because it doesnt matter that you measure that milk so exact if you are using a generic 'egg' and 'cup of flour' etc.
