Understanding the Statistical Measures
This tool provides a comprehensive set of statistical measures to help you understand your dataset. All calculations are performed client-side in your browser, ensuring your privacy.
Measures of Central Tendency
These values describe the central position of a dataset.
- Mean (Average): The sum of all values divided by the number of values. It is sensitive to outliers.
- Median: The middle value of a sorted dataset. It is not affected by outliers.
- Mode: The value that appears most frequently. A dataset can have one, many, or no modes.
Measures of Spread
These values describe how spread out the data points are.
- Range: The difference between the maximum and minimum values. $$ \text{Range} = \text{Max} - \text{Min} $$
- Quartiles (Q1 & Q3): The values that divide the sorted dataset into four equal parts.
- First Quartile (Q1): The median of the lower half of the dataset.
- Third Quartile (Q3): The median of the upper half of the dataset.
- Interquartile Range (IQR): The range of the middle 50% of the data. It is the difference between the third and first quartiles. $$ \text{IQR} = \text{Q3} - \text{Q1} $$
We also provide the total number of values (Count) and their sum (Sum), along with the smallest (Minimum) and largest (Maximum) values.
