17. 離差的度量 (Measures of Dispersion)

離差的度量 (Measures of Dispersion) 可理解為”睇吓到底D數據有幾分散”。

喺基礎課題入面,大家學咗

  • 離差的概念 (Concept of Dispersion)
  • 分佈域和四分位數間距的概念 (Concepts of Range and Inter-quartile Range)
  • 製作及闡釋框線圖及使用框線圖比較不同組別的數據分佈 (Constructing and Interpreting the Box-and-Whisker Diagram and Using it to Comparing the Distributions of Different Sets of Data)
  • 製作分組數據和不分組數據的標準差之概念 (Concept of Standard Deviation for Both Grouped and Ungrouped Data Sets)
  • 使用合適的量度方法比較不同組別數據的離差 (Comparing the Dispersions of Different Sets of Data Using Appropriate Measures)

嚟到非基礎課題,大家要學

  • 標準差在涉及標準分和正態分佈的現實生活問題時的應用 (Applications of Standard Deviation to Real-life Problems involving Standard Scores and the Normal Distribution)
  • 不同情況對數據的離差之影響 (Effect of the Different Operations on the Dispersion of the Data)
