❓ Frequently Asked Questions

What is the difference between mean, median, and mode?

Mean is the average of all values, median is the middle value when data is sorted, and mode is the most frequently occurring value. Each measures central tendency differently and is useful in different scenarios.

When should I use standard deviation vs variance?

Standard deviation is more intuitive as it's in the same units as your data, while variance is in squared units. Use standard deviation for reporting and interpretation, variance for mathematical calculations and comparisons.

What are quartiles and how are they calculated?

Quartiles divide your data into four equal parts. Q1 (25th percentile) and Q3 (75th percentile) help identify the spread of your data. The interquartile range (IQR = Q3 - Q1) measures the middle 50% of your data.

How does outlier detection work?

Our tool identifies outliers as values that fall beyond 2 standard deviations from the mean. This helps identify data points that may be errors or represent unusual observations that could skew your analysis.

Can I use this calculator for large datasets?

Yes, the calculator can handle large datasets efficiently. However, for very large datasets (thousands of values), consider using specialized statistical software for more advanced analysis and visualization features.
