A sample of n=8 scores has SS=50. If these same scores were a population ,then
the SS value for the population would be____
a.50 b.greater c.less than 50
d.impossible to determine without additional infomation
助教解答為
50/7=SS/8
SS>50
選b
可是我認為 同樣一筆資料
當樣本或當母群體的平均數不是一樣嗎
例如資料2 4 6 8
樣本平均數或母群體平均數都是5
那樣本或母體的SS應該會相同才對吧
懇請高手開示~~
