Frequently Asked Questions (FAQ)

What's the difference between descriptive and inferential statistics?

Descriptive statistics summarize and describe data features (mean, median, standard deviation). Inferential statistics make predictions or inferences about populations based on samples (hypothesis testing, confidence intervals). Our calculator provides comprehensive descriptive statistics with basic inferential capabilities.

When should I use median instead of mean?

Use the median when your data has outliers or is skewed, as it's less affected by extreme values. Use the mean for normally distributed data without significant outliers. Our calculator automatically flags potential skewness and recommends appropriate measures.

How do I interpret standard deviation results?

Small standard deviation indicates data points are close to the mean (low variability). Large standard deviation shows data is spread out (high variability). In normal distributions, about 68% of data falls within ±1 standard deviation from the mean.

What do skewness and kurtosis tell me about my data?

Skewness measures distribution asymmetry (positive = right-skewed, negative = left-skewed). Kurtosis measures tail heaviness (high kurtosis = heavy tails, more outliers). Our calculator provides interpretations and visualizations for these higher-order moments.
