What is the difference between sample standard deviation and population standard deviation?

Sample standard deviation divides the sum of squared differences by (n - 1) using Bessel's correction to remove sample bias. Population standard deviation divides by N when the complete dataset represents the entire population.

How does Tukey's rule identify outlier data points?

Tukey calculates the Interquartile Range (IQR = Q3 - Q1). The inner fences are placed at [Q1 - 1.5*IQR] and [Q3 + 1.5*IQR]. Any data point lying beyond these fences is classified as an outlier.

What does positive or negative skewness indicate about a dataset?

Skewness measures distribution asymmetry. A value of 0 indicates a symmetric bell curve. Positive skewness (> 0) means the tail extends to the right (e.g., income), while negative skewness (< 0) indicates a long left tail.

Why is the Median preferred over the Mean for skewed distributions?

The mean is sensitive to extreme outliers; a single massive value pulls the average upward. The median represents the exact 50th percentile rank, providing an uncorrupted measure of central tendency.

Does the calculator handle duplicate values or negative numbers?

Yes. It seamlessly processes positive, negative, and fractional floating-point numbers, and accurately determines single or multimodal distribution values.
