The p-value is a measure that indicates the probability of obtaining test results at least as extreme as the observed results, assuming the null hypothesis is true. The significance level, often denoted as alpha (α), is a predetermined threshold set by the researcher (commonly 0.05) to decide whether to reject the null hypothesis. If the p-value is less than or equal to the significance level, the results are considered statistically significant, leading to the rejection of the null hypothesis. Essentially, the p-value is the outcome of the statistical test, while the significance level is the criterion for making a decision based on that outcome.

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.
Difference between confidence level and significant level?
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.

Why is the level of significance always small?
The significance level is always small because significance levels tell you if you can reject the null-hypothesis or if you cannot reject the null-hypothesis in a hypothesis test. The thought behind this is that if your p-value, or the probability of getting a value at least as extreme as the one observed, is smaller than the significance level, then the null hypothesis can be rejected. If the significance level was larger, then statisticians would reject the accuracy of hypotheses without proper reason.
Difference between p value and level of significance?
P- value is the probability that the given null hypothesis is true and the level of significance is the chance in a hundred or thousand off occurence of an event i an outcome

What are the three parts of a hypotnesis statement?
A hypothesis statement consists of three parts: the null hypothesis (H0), the alternative hypothesis (Ha), and the level of significance (alpha). The null hypothesis states that there is no relationship or difference between variables, while the alternative hypothesis suggests the presence of a relationship or difference. The level of significance determines the threshold for accepting or rejecting the null hypothesis based on statistical testing.

Why null hypothesis it is tested at 0.05 level of significance?
A significance level of 0.05 is commonly used in hypothesis testing as it provides a balance between Type I and Type II errors. Setting the significance level at 0.05 means that there is a 5% chance of rejecting the null hypothesis when it is actually true. This level is widely accepted in many fields as a standard threshold for determining statistical significance.
