數學會考有咩要注意？新課程有咩？

絕對誤差

Case 1 : actual value is known
絕對誤差 = Difference between actual value and estimated value

e.g. 估計銀包有 $2360, 但其實有 $2359.5
絕對誤差 = 2360 - 2359.5 = $0.5



Case 2 : actual value is NOT known
咁就要睇下佢比果個約數係取幾多位ge近似值la

e.g. 度到體溫係 36.5度
由於 36.5 呢個數係取最接近 ge 0.1度
所以最大絕對誤差 = 0.1 / 2 = 0.05 度

Gd luck in CE~~希望幫到你la~~

唔係呀嘛~
數學都洗問...
做就緊係靠自己架啦...
唉.......
