Decision Making: P-value Method

6.5K
The process of hypothesis testing based on the P-value method includes calculating the P- value using the sample data and interpreting it.
First, a specific claim about the population parameter is proposed. The claim is based on the research question and is stated in a simple form. Further, an opposing statement to the claim  is also stated. These statements can act as null and alternative hypotheses:  a null hypothesis would be a neutral statement while the alternative hypothesis can...

P-value01:10

P-value

8.1K
P-value is one of the most crucial concepts in statistics.
P-value stands for the probability value.  P-value is the probability that, if the null hypothesis is true, the results from another randomly selected sample will be as extreme or more extreme as the results obtained from the given sample.
A large P-value calculated from the data indicates to  not reject the null hypothesis. But a higher P-value does not mean that the null hypothesis is true. The smaller the P-value, the more...

Significance Testing: Overview

9.5K
Significance testing is a set of statistical methods used to test whether a claim about a parameter is valid. In analytical chemistry, significance testing is used primarily to determine whether the difference between two values comes from determinate or random errors. The effect of a particular change in the measurement protocol, analyst, or sample itself can cause a deviation from the expected result. In the case of a suspected deviation/outlier, we need to be able to confirm mathematically...

Bonferroni Test01:10

Bonferroni Test

3.2K
The Bonferroni test is a statistical test named after Carlo Emilio Bonferroni, an Italian mathematician best known for Bonferroni inequalities. This statistical test is a type of multiple comparison test to determine which means are different than the rest. Bonferroni test can minimize the Type 1 error by reducing the significance level alpha, which otherwise increases with sample pairs.
The means of different samples are first paired in all possible combinations.
The null hypothesis of the...

Statistical Hypothesis Testing01:16

Statistical Hypothesis Testing

5.0K
Hypothesis testing is a critical statistical procedure facilitating informed, evidence-based decisions. It begins with a hypothesis, which is a tentative explanation, or a prediction about a population parameter. This hypothesis can be either a null hypothesis (H0), indicating no effect or difference, or an alternative hypothesis (Ha), suggesting an effect or difference.
Statistical significance measures the probability that an observed result occurred by chance. If this probability, known as...

Critical Region, Critical Values and Significance Level

12.9K
The critical region, critical value, and significance level are interdependent concepts crucial in hypothesis testing.
In hypothesis testing, a sample statistic is converted to a test statistic using z, t, or chi-square distribution. A critical region is an area under the curve in  probability distributions demarcated by the critical value. When the test statistic falls in this region, it suggests that the null hypothesis must be rejected. As this region contains all those values of the...

Summary
This summary is machine-generated.

Null-hypothesis Bayesian testing (NHBT) offers advantages that complement classical frequentist statistics, including null-hypothesis significance testing (NHST). Reporting both P-values and Bayes factors enhances clarity in healthcare research analysis.

Area of Science:

  • Healthcare research
  • Statistical analysis

Background:

  • Frequentist statistics, including null-hypothesis significance testing (NHST), is standard in medical and nursing research.
  • Null-hypothesis Bayesian testing (NHBT) is gaining recognition for its utility in healthcare research.

Purpose of the Study:

  • To advocate for the integration of Bayes factors from NHBT alongside P-values from NHST in research analyses.
  • To enhance the interpretation of research findings in healthcare.

Main Methods:

  • Comparative analysis of NHST and NHBT methodologies.
  • Exploration of the complementary roles of P-values and Bayes factors.

Main Results:

  • NHBT provides statistical and practical benefits that supplement NHST.
  • Combining P-values and Bayes factors aids in interpreting results that may be ambiguous with P-values alone.

Conclusions:

  • NHBT is a valuable tool that complements NHST in healthcare research.
  • Reporting both P-values and Bayes factors improves the clarity and robustness of statistical findings.
