[商管] 成大企研95統計
這題沒google到 所以想請問一下這題選擇
13.The sampling error is the
A) same as the standard error of the mean
B) difference between the value of the sample mean and the value of the
population mean
C) error caused by selecting a bad sample
D) standard deviation multiplied by the sample size.
這題我選不太出來 免強選C
高點給的答案是B
但根據陳正倉 林惠玲那本書 B選項的敘述應該還要包含nonsampling error吧?
謝謝各位先進!! :)
