Statistics Calculator Explained – Mean, Median, Mode & More
The Statistics Calculator helps you analyze numerical datasets by finding the **mean, median, mode, range, variance, and standard deviation**. It’s useful for students, researchers, and analysts who need accurate insights from data quickly.
Key Statistical Concepts
- Mean (Average): The sum of all data points divided by the number of values.
- Median: The middle value when data is arranged in order.
- Mode: The number that appears most often.
- Range: Difference between the maximum and minimum values.
- Variance: The average squared deviation from the mean.
- Standard Deviation: The square root of variance, showing data spread.
Sample vs Population
For **sample data**, divide by *(n - 1)* when calculating variance and standard deviation. For **population data**, divide by *n*.
Why Use a Statistics Calculator?
- Quickly analyze datasets without manual math.
- Identify trends, dispersion, and central tendencies.
- Ideal for education, business analytics, and research.
FAQs
