The confidence level refers to the probability that a statistical estimate, such as a confidence interval, contains the true population parameter, commonly expressed as a percentage (e.g., 95%). In contrast, the significance level (often denoted as alpha, α) is the threshold used in hypothesis testing to determine whether to reject the null hypothesis, typically set at values like 0.05 or 0.01. While the confidence level reflects the reliability of an estimate, the significance level indicates the risk of making a Type I error (incorrectly rejecting a true null hypothesis). Essentially, confidence levels relate to estimation, while significance levels pertain to hypothesis testing.

What is the level of measurement for Pain level left scale of 0 to 10 right?
It is measurement on an ordinal scale. Level 1 is less than level 2 which is less than level 3 and so on. But the difference between levels 1 and 2 is not related to the difference between levels 2 and 3, etc.
What is the most controllable method of increasing the precision of or narrowing the confidence interval?
Confidence intervals represent an interval that is likely, at some confidence level, to contain the true population parameter of interest. Confidence interval is always qualified by a particular confidence level, expressed as a percentage. The end points of the confidence interval can also be referred to as confidence limits.
What Happens To The Width Of The Confidence Interval If You Decrease The Confidence Level Decrease The Sample Size or Decrease the margin of error?
The width of the confidence interval willdecrease if you decrease the confidence level,increase if you decrease the sample sizeincrease if you decrease the margin of error.

How do you tell if a wilcoxon test is significant?
To determine if a Wilcoxon test is significant, you compare the p-value obtained from the test to your chosen significance level (commonly 0.05). If the p-value is less than or equal to this threshold, you reject the null hypothesis, indicating that there is a statistically significant difference between the groups being compared. Additionally, examine the test statistic and confidence intervals for further insight into the effect size and direction of the difference.

Is there a difference in 600ft above sea level and 3300ft above sea level?
Yes, there is a significant difference between 600ft and 3300ft above sea level. At 3300ft above sea level, you are much higher in elevation compared to 600ft, which can affect things like temperature, air pressure, and oxygen levels.
