人的反應時間係系統誤差定係隨機誤差??

人的反應時間(reaction time of human being)係系統誤差(systematic error)定係隨機誤差(random error)??

New Way,,CW SHAM話係systematic,,,

Ken.Chan話係random,,,

所以我想問清楚D,,,@@

同埋我想要少少systematic error & random error既定義啦,,,分別同埋例子,,,

    If you refer to a the reaction time of a particular person, it is a systematic error. But if you refer to the reaction time of a group of persons, it is a random erro, because different person have different reaction time. Some act quicker than the others.

    Generally, random error is unpredictable and can only be estimated by statistical means, whereas systematic error can be predicted.

    〔人的反應時間係系統誤差定係隨機誤差??〕:人的反應時間(reaction time of human being)係系統誤差,人體反應時間可分成三個系統階段完成,當拿一枝針刺入身體時,系統便出現(一)由眼接受信息進入腦信息系統;(二)由植物神經體系接受信息進入腦信息系統;(三)由體躯神經體系接受信息進入腦信息系統。傳送速度分別為光、氣、血三階段完成,然後合成産生反應…痛疼的感覚。

    系統誤差,係一d固定既error

    例如,實驗儀器唔準,

    每次result都差唔多一樣

    改善方法係整control set up.

    隨機誤差,係一d次次都唔同既error.

    例如用stop watch, 每次量都唔同,

    改善方法係做多幾次去減小error.

    我覺得人的反應時間其實係系統誤差定隨機誤差都得,

    睇情況而定
