Mean Absolute Percent Error 平均绝对百分比误差 ; 绝对误差百分比之平均 ; 误差百分比之平均 ; 预测结果误差评估标准采用平均绝对百分误差
mean percent error [统计] [数] 平均百分误差
absolute percent error 绝对百分比错误
rms percent error [统计] 均方根百分误差
Mean Square Percent Error 均方百分比误差
root-mean-square percent error 均方根百分误差
relative percent error 的相对百分误差
percent error in volume 量误差百分比
MPE Mean Percent Error 平均差错百分比
That is one out of 300, so that is only a one-third percent error.
那也就是1/300左右,因此误差只有0。33%左右。
There were 3.4482 percent error between theoretical calculation and experiment.
理论计算的结果和实验结果比较误差在3.4482%左右。
H by 9.9, is 60.2. There's a five percent error 3 and a five percent error is indeed three.
最大值是3。07,乘以2,3。07,is, h, max——,i, multiplied, by, two,然后乘以9。8,得到60。2,然后有5%的误差,的确是。
So this is the percent error and what you see here is that if the number is below the zero line it means people underestimated the calories, and the bars that go above means people overestimated the calories.
这是百分比误差,你们看,如果数字低于零,这表示人们低估了卡路里,高于零表示人们高估了卡路里
Highly educated people, a lot of you probably care a lot about food, think about labels, read them and things like that, not one person out of the 300-350 people in this room guessed correctly within ten percent margin of error.
你们受过高等教育,注意饮食健康,关注食品标签,等等,在10%的误差幅度下,在300-350个人中,没有一个人估计正确
