某零件C工序加工原定额为14工分/件,已知其实耗工时统计资料为11、13、14、12、10、9(工分/件)。 试根据这些资料求出平均先进值和先进平均值。

答案

参考答案:

平均先进值的计算

①方法一:先求平均数,再将平均值与完成最好的实耗工时相加,求出二次平均数。

②方法二:先求平均数,再将平均值与所有比平均值先进的实耗工时相加,除以项数,求出二次平均数。

③方法三:先求平均数,再将平均值与两个最先进和一个最落后的实耗工时相加,除以项数,求出二次平均数。

④方法四:先剔除已知数据中的最大的一个和最小的一个实耗工时,然后再按上述的第二种方法求出二次平均数。

(2)先进平均值的计算 先进平均工时是指在一次平均数之外,所有先进数值的二次平均数。其计算方法是: ①先求一次平均数,即: ②再求出先进数值的平均数,即:

In a national spelling contest in America, an 11-year-old girl was asked to spell a certain word. But with her soft voice the judges were not sure if she spelled the word with the letter A or E.  小题1:   At that time, the girl knew she had misspelled the word.
