常见问题
What is the difference between mean, median, and mode?
Mean is the average (sum divided by count). Median is the middle value when sorted. Mode is the most frequently occurring value.
When should I use the average?
Use the average when your data is fairly evenly distributed without extreme outliers. For skewed data, the median may be more representative.
