Skewness Calculator

Welcome to our Skewness Calculator guide! Skewness is a fundamental concept in statistics that measures the asymmetry or lack of symmetry in a data distribution. It provides insights into the shape, central tendency, and variability of data, playing a pivotal role in descriptive statistics and data analysis. In this article, we’ll delve deep into the definition, types, interpretation, and computation of skewness, and showcase how our specialized calculator simplifies skewness calculations.

Skewness Calculator Overview

What is Skewness?

Skewness refers to the measure of the asymmetry or lack of symmetry in a probability distribution. It indicates whether the data distribution is skewed to the left (negatively skewed), centered (symmetric), or skewed to the right (positively skewed).

Types of Skewness

1. Negative Skewness (Left Skewness):
   • The tail of the distribution extends towards the lower values.
   • Mean < Median < Mode
2. Positive Skewness (Right Skewness):
   • The tail of the distribution extends towards the higher values.
   • Mean > Median > Mode
3. Zero Skewness:
   • The distribution is symmetric.
   • Mean = Median = Mode

Calculation of Skewness

The formula for computing skewness using Pearson’s first coefficient of skewness is:

Skewness=3(Mean−Median)Standard DeviationSkewness=Standard Deviation3(Mean−Median)​

How the Calculator Works

Our Skewness Calculator simplifies skewness calculations by:

1. Input Data: Enter the dataset values separated by commas or spaces.
2. Calculate Skewness: Click the “Calculate” button to compute the skewness value based on the input data.
3. View Results: Examine the computed skewness value and its interpretation (negative, positive, or zero skewness).

A “Skewness Calculator” is a statistical tool used to measure the asymmetry or lack of symmetry in a probability distribution. Skewness indicates whether the data distribution is skewed to the left (negative skewness), skewed to the right (positive skewness), or approximately symmetrical (zero skewness).

How to Use the Skewness Calculator

1. Input the data set or sample for which you want to calculate the skewness. The data can be entered as a list of numbers or as a series separated by commas or spaces.
2. Specify the type of skewness calculation you want to perform (Fisher’s skewness or Pearson’s skewness).
3. Click on the “Calculate” button to obtain the skewness value.

Data Set/Sample: [__________]

Type of Skewness Calculation:

• [Fisher’s Skewness]
• [Pearson’s Skewness]

[Calculate]

Example:

Suppose you have a data set representing the daily temperatures in degrees Celsius for a week: 22, 23, 22, 21, 23, 24, 25.

Input the data set: 22, 23, 22, 21, 23, 24, 25
Select Fisher’s Skewness or Pearson’s Skewness
Click “Calculate.”

The calculator will compute the skewness value for the given data set, indicating whether the distribution of temperatures is skewed to the left, skewed to the right, or approximately symmetrical.

Step-by-Step Guide to Using the Calculator

1. Enter Data: Input the dataset values separated by commas or spaces.
2. Initiate Calculation: Click the “Calculate” or “Compute” button to compute the skewness value.
3. Review Results: Analyze the computed skewness value and its corresponding interpretation provided by the calculator.
