[A review of statistical analysis methods in measurement data]

Area of Science:

• Clinical Biostatistics
• Data Analysis in Healthcare
• Enumeration Data Analysis

Context:

• Clinical research frequently generates enumeration data, which are categorical variables derived from frequency counts.
• Understanding the nature of enumeration data is crucial for appropriate statistical analysis in medical studies.

Purpose:

• To review and highlight specific statistical methods applicable to enumeration data.
• To assist clinicians and researchers in choosing the correct analytical techniques for their categorical variables.

Summary:

• Enumeration data, based on frequency counts of categorical variables, requires specialized statistical approaches.
• Descriptive statistics (rates, proportions) and inferential statistics (confidence intervals, chi-square tests) are key methods.
• This review focuses on guiding the selection of these methods based on data characteristics.

Impact:

• Facilitates more accurate and reliable analysis of clinical research data.
• Improves the quality of evidence derived from studies using categorical variables.
• Empowers researchers to confidently apply appropriate statistical tests for enumeration data.
