错题集

四年级上册数学错题集一、大数的认识1. 题目：读数：300005000，错误答案：三亿零五千。

解析：读这个数时，从高位读起，亿级是3，读作三亿；万级都是0，只读一个零；个级是5000，读作五千。

正确答案应该是三亿零五千。

这里容易出错的地方在于万级的0的读法，每级末尾不管有几个0都不读，其他数位上有一个0或连续几个0，都只读一个零。

2. 题目：写数：三十亿零三百，错误答案：300000300。

解析：三十亿零三百，十亿位是3，百位是3，其他数位是0，正确写法应该是3000000300。

错误原因是没有正确理解每个数位上的数字，导致少写了0。

二、公顷和平方千米1. 题目：1公顷 =（）平方米，错误答案：100。

解析：因为1公顷是边长为100米的正方形的面积，根据正方形面积 = 边长×边长，100×100 = 10000平方米，所以1公顷 = 10000平方米。

这里错误是对公顷和平方米的换算关系没有牢记。

2. 题目：一个长方形果园长500米，宽200米，这个果园的面积是多少公顷？错误答案：直接用500×200 = 100000（平方米），回答100000公顷。

解析：首先算出果园面积为500×200 = 100000平方米，然后将平方米换算成公顷，因为1公顷 = 10000平方米，所以100000平方米=10公顷。

错误在于没有进行单位换算。

三、角的度量1. 题目：用量角器量角时，角的一边与量角器内圈0°刻度线重合，另一边指向120°，这个角是（）度，错误答案：120°。

解析：当角的一边与量角器内圈0°刻度线重合时，另一边指向120°，这个角应该是60°。

因为内圈刻度是按照逆时针方向读数的，而我们通常用量角器量角时，按照顺时针方向读数是外圈刻度，这里容易混淆内圈和外圈刻度的读数方法。

2. 题目：一个平角分成两个角，其中一个角是锐角，另一个角是（）角，错误答案：锐角。

禁止机动车通行：表示禁止某种机动车通行。

八年级上册数学错题八年级上册数学错题集一、三角形错题 1：一个三角形的两边长分别为 3 和 6，第三边长是方程x^2 10x + 21 = 0的根，则三角形的周长为（）A. 12B. 16C. 12 或 16D. 不能确定解析：解方程x^2 10x + 21 = 0，即(x 3)(x 7) = 0，解得x = 3或x = 7。

当第三边长为 3 时，因为 3 + 3 = 6，不满足三角形两边之和大于第三边，所以舍去。

当第三边长为 7 时，三角形的周长为 3 + 6 + 7 = 16。

故选 B。

错题 2：在\triangle ABC中，\angle A = 50^{\circ}，\angle B = \angle C，则\angle B的度数为（）A. 65°B. 50°C. 80°D. 40°解析：因为\angle A + \angle B + \angle C = 180^{\circ}，且\angle B = \angle C，所以\angle B = (180^{\circ}50^{\circ})÷ 2 = 65^{\circ}故选 A。

B 选项，因为AB = AD，∠BAC = ∠DAC，AC = AC，根据 SAS 可判定\triangle ABC ≌ \triangle ADC。

C 选项，因为AB = AD，∠B = ∠D = 90°，AC = AC，根据 HL 可判定\triangle ABC ≌ \triangle ADC。

协和版：测得一组资料，如身高或体重等，从统计上讲，算术均数与其标准差的大小无关在指定尿铅95％参考值范围时，宜采用界值为：<P95σ－X表示的含义是总体均数的标准误估计值两小样本均数比较时，若方差不齐，可选择t’检验区间－X ±1.96S－X可用来估计总体均数的95％的可信区间配对设计资料的t检验，其检验假设为差值的总体均数等于0成组设计两样本比较的t检验，其检验假设为两总体均数相等在完全随机设计的方差分析中，必然有SS总＝SS组间＋SS组内随机区组设计的方差分析中，V区组＝V总－V处理－V误差随机区组设计要求区组内个体差异越小越好，区组间差异越大越好。

方差分析中，多个试验组与一个对照组均数的多重比较，宜采用q检验对于服从二项分布的率或百分比资料进行方差分析，可考虑进行平方根反正弦变换标化率不反映某现象发生的实际水平。

经调查甲乙两市的冠心病粗死亡率为45/10万，按标准人群年龄构成标化后，甲市为52/10万，乙市为40/10万，故可认为甲市年龄别人口构成较乙市年轻。

欲比较两工厂工人某职业病患病率的高低，需假设两厂该工种工人的工龄构成相同。

直接标准化法选择的标准是各年龄组标准人口构成比或各年龄组标准人口数。

计算动态数列指标可以是实际数、平均数、率、构成比HBsAg总体阳性率95％可信区间表示π一定时，随机抽取n相等的100个样本率，至少有95个推断正确。

总体率（1-α）可信区间指求得的区间包含总体率的可能性为（1-α）在率比较的假设检验中，由于观察单位数较小，得P>0.05，若适当增加样本观察单位数，可增大理论频数。

在配对设计差值的符号秩和检验中，绝对值等于3的差值有-3、-3、3、3。

如果它们的位次为4、5、6、7，则第2个-3的秩次应为-5.5配对比较的秩和检验，若检验假设H0成立，则正秩和与负秩和相差不会很大。

四组等级资料比较宜采用秩和检验。

某医师调查得10名女中学生体重X（kg）与肺活量Y（L），经直线回归分析知，b＝0.0748，若t b>t0.05，8，按α＝0.05水准，可认为肺活量随体重增加而增加。
