## Overview

The Skewness Analyzer is a professional statistical tool designed to measure the asymmetry of your probability distribution, helping you identify data patterns and deviations from a normal distribution.

## Inputs

- **Data Input** (textarea): Enter your data values separated by commas or new lines... Examples: - Single column: 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 - Multiple columns: 1, 5, 3, 8, 2, 9, 4, 7, 6, 10 - One value per line: 1 2 3 4 5
- **Data Format** (select)
- **Analysis Type** (select)
- **Detect Outliers** (checkbox): Identify and analyze outliers in the dataset using IQR method

## When to use

- When you need to determine if your dataset is skewed to the left or right.
- When validating whether your data follows a normal distribution for statistical modeling.
- When identifying potential outliers that may be distorting your data analysis results.

## How it works

- Input your numerical data values separated by commas or new lines.
- Select your data format and choose the depth of analysis, such as basic skewness or comprehensive kurtosis reporting.
- Enable the outlier detection feature to automatically flag values using the Interquartile Range (IQR) method.
- Review the generated statistical report to understand the symmetry and distribution characteristics of your dataset.

## Use cases

- Financial analysts evaluating the distribution of stock returns to identify market volatility.
- Quality control engineers checking manufacturing measurements for consistency and bias.
- Researchers verifying the normality of survey response data before performing parametric tests.

## Frequently asked questions

### What does a skewness value of zero indicate?

A skewness value of zero indicates that the data is perfectly symmetrical, typically representing a normal distribution.

### How does the tool detect outliers?

The tool uses the Interquartile Range (IQR) method to identify values that fall significantly outside the expected range of your dataset.

### What is the difference between basic and comprehensive analysis?

Basic analysis provides the skewness coefficient, while comprehensive analysis includes kurtosis to measure the 'tailedness' of the distribution.

### Can I analyze multiple columns of data at once?

Yes, by selecting the 'Multiple columns' format, the tool will flatten all provided values into a single dataset for analysis.

### Is my data stored on your servers?

No, this tool processes your data locally in your browser to ensure your information remains private and secure.

- [CURB-65 vs PSI vs SMART-COP (Pneumonia Severity Comparison)](https://elysiatools.com/en/tools/curb-65-vs-pneumonia-severity): Compare three pneumonia severity scores side-by-side from one set of inputs to support concordance reading. CURB-65 (0-5: Confusion, Urea, RR, BP, age ≥65) — quick bedside triage; PSI/PORT (Fine 1997, 5 risk classes) — the most accurate mortality stratification, more complex; SMART-COP (0-10, 2 points each for SBP <90 and hypoxia, 1 point each for multilobar CXR, albumin <3.5, RR ≥25, tachycardia ≥125, confusion, pH <7.35) — predicts need for ICU respiratory/vasopressor support. Each score has a different focus: CURB-65 is fast; PSI is more precise; SMART-COP identifies who needs ICU. The tool reports each score's total/category/interpretation and an agreement analysis (whether all three point to outpatient/admission/ICU). When scores disagree, favor the more conservative disposition. Derived from Lim 2003, Fine 1997, Charles 2008. Not medical advice.
