快速开始
- 访问 HeronTool 的 Average (平均数) 工具页面。
- 在输入框中粘贴或输入一组数值,用逗号、空格或换行分隔。
- 点击“计算”按钮,工具自动显示算术平均值、中位数、众数和标准差等统计量。
高级用法
- 加权平均:如需加权,在每项后添加冒号和权重(如
10:2, 20:3),工具自动识别并计算。 - 数据清洗:使用“过滤空值”选项,自动忽略空行和非数字字符,确保结果准确。
- 结果导出:点击“复制结果”可一键复制所有统计量,方便粘贴到报告或文档。
实际应用示例
假设您有销售数据:120, 150, 130, 170, 160。输入后,Average 工具会显示平均值 146,中位数 150,标准差约 20.4。这有助于快速判断业绩波动范围。

Quick Start
- Go to HeronTool's Average (平均数) tool page.
- Paste or enter a set of numbers in the input box, separated by commas, spaces, or newlines.
- Click the "Calculate" button – the tool instantly shows arithmetic mean, median, mode, and standard deviation.
Advanced Usage
- Weighted Average: For weights, append a colon and weight to each value (e.g.,
10:2, 20:3); the tool auto-detects and computes. - Data Cleaning: Enable the "Filter Empty Values" option to ignore blank lines and non-numeric characters, ensuring accuracy.
- Export Results: Click "Copy Results" to copy all statistics at once, ready for pasting into reports or docs.
