Which of the following is true of descriptive statistics？
A．It leads to increased variability
B．It solves all numerical problems
C．It simplifies unwieldy masses of data
D．It changes qualitative variables to quantitative variables
参考答案
正确答案：C
解析：文章第三段最后一句话“Descriptive statistics is tool for describing or summarizing or reducing to comprehensible form. the properties of an otherwise unwieldy mass of data．”说明描述统计学是对大量杂乱的数据性质进行描叙、总结或者简化以更易于理解的工具。所以C正确。
