A、300 人以下,300-500 人 B、300 人以下,300-500 人(不含 300) C、300 人以下,301-500 人 D、300 人以下,310-500 人 E、299 人以下,300-499 人 4、 在工业普查中( BCE )。 A、工业企业总数是统计总体 B、每一个工业企业是总体单位 C、固定资产总额是统计指标 D、机器台数是连续变量 E、 职工人数是离散变量 5、以下属于离散变量的有( BE )。 A、进口的粮食数量 B、洗衣机台数 C、每千人医院床位数 D、人均粮食产量 E、城乡集市个数 6、下列各项中,属于连续型变量的有( ACD )。 A、基本建设投资额 B、岛屿个数 C、国民生产总值中三次产业比例 D、居民生活费用价格指数 E、就业人口数 四、简答题

1、“统计”一词有哪几种含义? 答:统计有三种理解:统计工作,统计资料,统计学,

三者关系:统计工作与统计资料是统计过程与活动成果的关系,统计工作与统计学是统计实践与统计理论的关系,统计

工作先于统计学。

统计学研究的对象是统计研究所要认识的客体。

2、什么是变量?举例说明离离散变量和连续变量? 答:变异标志可以是品质标志,也可以是数量标志。变异标志又被称为变量,即变量泛指一切可变标志,既包括可变的数量

标志,也包括可变的品质标志。在统计中的变量是用于说明现象某种特征的概念。如“商品销售额”、“受教育程度”、“产品

的质量等级”等都是变量。变量的具体数值表现称为变量值。比如商品销售额可以是 20 万元、30 万元、50 万元等等,这些 数字就是变量值。统计数据就是统计变量的具体表现。

举例离散变量:对家庭总体按家庭成员数分为以下几组:一个人的,两个人,三个人的,四个人的,五个人的,六个人的组,

这里“两个”“三个”等,就是单项式分组的组名称,具有离散型数量特征

举例连续变量由于不能一一列举变量值,帮不能作单项式分组,只能进行组距式分组。如,工人按工资分组,可作如下组距

式分组:1300~1400 元,1400~1500 元,1500~1600 元等。 3、请分别说明普查与抽样调查的特点 答:普查是专门组织的、一般用来调查属于一定时点上社会经济现象数量的全面调查。普查的特点:(1)普查是一种不连续调 查。因为普查的对象是时点现象,时点现象的数量在短期内往往变动不大,不需做连续登记。(2)普查是全面调查。它比任何 其它调查方法都更能掌握全面、系统的,反映国情国力方面的基本统计资料。(3)普查能解决全面统计报表不能解决的问题。 因为普查所包括的单位、分组目录、指标内容比定期统计报表更广范、更详细,所以能取得更详尽的全面资料。(4)普查要耗 费较大的人力、物力和时间,因而不能经常进行。

抽样调查的特点:(1)抽样调查是一种非全面调查,但其目的是要通过对部分单位的调查结果来推断总体的数量特征。(2) 抽样调查是按照随机原则从全部总体单位中来抽选调查单位。所谓随机原则就是总体中调查单位的确定完全由随机因素来决

定,单位中选与不中选不受主观因素的影响,保证总体中每一单位都有同等的中选可能性。

4、调查方案包括哪几个方面的内容? 答:统计调查方案的内容包括: (1)确定调查任务与目的; 目;

(2)确定调查对象与调查单位;

(3)确定调查项

(4)确定调查时间和调查期限; (5)制定调查方案的组织实施计 5、请根据第三章第二节和第三节的内容总结变量分配数列编制的步骤 ①将原始资料按其数值大小重新排列

只有把得到的原始资料按其数值大小重新排列顺序,才能看出变量分布的集中趋势和特点,为确定全距,组距和组数作准备. ②确定全距

全距是变量值中最大值和最小值的差数.确定全距,主要是确定变量值的变动范围和变动幅度.如果是变动幅度不大的离散变量, 即可编制单项式变量数列,如果是变量幅度较大的离散变量或者是连续变量,就要编制组距式变量数列. ③确定组距和组数

前面已经介绍过组距数列有等距和不等距之分,应视研究对象的特点和研究目的而定.

组距的大小和组数的多少,是互为条件和互相制约的.当全距一定时,组距大,组数就少;组距小,组数就多.在实际应用中,组距应 是整数,最好是 5 或 10 的整倍数.在确定组距时,必须考虑原始资料的分布状况和集中程度,注意组距的同质性,尤其是对带有根 本性的质量界限,绝不能混淆,否则就失去分组的意义. 在等距分组条件下,存在以下关系: 组数=全距/组距 ④ 确定组限 组限要根据变量的性质来确定.如果变量值相对集中,无特大或特小的极端数值时,则采用闭口式,使最小组和最大组也都有下限 和上限;反之,如果变量值相对比较分散,则采用开口式,使最小组只有上限(用"XX 以下"表示),最大组只有下限(用"XX 以上表示). 如果是离散型变量,可根据具体情况采用不重叠组限或重叠组限的表示方法,而连续型变量则只能用重叠组限来表示. 在采用闭口式时,应做到最小组的下限低于最小变量值,最大组的上限高于最大变量值,但不要过于悬殊. ⑤ 编制变量数列 经过统计分组,明确了全距,组距,组数和组限及组限表示方法以后,就可以把变量值归类排列,最后把各组单位数经综合后填入 相应的各组次数栏中. 6、统计表由哪几个部分组成? 答:统计表由标题、横行和纵栏。数字资料等部分构成的。标题分为三种:总标题是表的名称,放在表的上端:横行标题或 称横标目,写在表的左方;纵栏标题或称纵标目写的表在上方。统计表的内容包括主词和宾词两个部分。 五、计算题

5、在什么条件下,加权算术平均数等于简单算术平均数( AED )。 A、各组次数相等 B、各组变量值不等 C、变量数列为组距数列 D、各组次数都为 1 E、各组次数占总次数的比重相等 6、中位数是(ADE )。 A、由标志值在数列中所处位置决定的 B、根据标志值出现的次数决定的 C、总体单位水平的平均值 D、总体一般水平的代表值 E、不受总体中极端数值的影响 7、标志变异指标可以( ABCD )。 A、反映社会经济活动过程的均衡性 B、说明变量的离中趋势 C、测定集中趋势指标的代表性 D、衡量平均数代表性的大小 E、表明生产过程的节奏性 8、下列指标属于相对指标的是( BDE )。 A、某地区平均每人生活费 245 元 B、某地区人口出生率 14.3% C、某地区粮食总产量 4000 万吨 D、某产品产量计划完成程度为 113% E、某地区人口自然增长率 11.5‰ 四、简答题 1、什么是相对指标? 结构相对指标、比例相对指标和比较相对指标有什么不同的特点?请举例说明。 答:结构相对指标是以总体总量为比较标准,计算各组总量占总体总量的比重,来反映总体内部组成情况的综合指标。比例 相对指标是总体不同部分数量对比的相对数,用以分析总体范围内各个局部之间比例关系和协调平衡状况。比较相对指标是 不同单位的同类指标对比而确定的相对数,借以说明同类现象在同一时期内各单位发展的不平衡程度。 2、什么是平均指标?在统计分析中的作用是什么? 答:平均指标又称统计平均数,主要用于反映社会经济现象总体各单位某一数量标志在一定时间、地点条件下所达到的一般 水平。在社会经济统计中,平均指标是最常用的一种综全指标。 作用:第一、反映总体各单位变量分面的集中趋势。第二、比较同类现象在不同单位的发展水平,用于说明生水平、经济效 益或工作质量的差距。第三、分析现象之间的依存关系。此外,平均指标经常被作为评价事物和问题决策的数量标准或参考。 3、什么是变异系数?变异系数的应用条件是什么?请写出标准差异系数的计算公式 答:变异系数:全距、平均差和标准差都有平均指标相同的讲师单位,也就是与各单位标志值的讲师单位相同。 变异系数的应用条件是:为了对比分析不同水平的变量数列之间标志值的变异程度,就必须消除数列水平高低的影响,这时 就要计算变异系数。 常用的是标准差系数
V6=6/?x

4、请分别写出简单算术平均数、加权算术平均数、加权调和平均数的计算公式并分别说明其应用条件。

?x

答:①简单算术平均数 x ?

, 它适用于未分组的统计资料;如果已知各单位标志值和总体单位数,可用简单算术平均数

n

? xf

计算。②加权算术平均数 x ?

,它适用于分组的统计资料,如果已知各组的变量值和变量值出现的次数,则可用加权算

?f

?m

术平均数。③调和平均数 x ?

,在实际工作中,有时由于缺乏总体单位数资料,而不能直接计算平均数,这时就可以采

一、判断题

1、抽样推断是利用样本资料对总体的数量特征进行的一种统计分析方法,因此不可避免的会产生误差,这种误差的大小是不

能进行控制的。(× )

2、从全部总体单位中按照随机原则抽取部分单位组成样本,只可能组成一个样本。(× )

3、抽样估计的置信度就是表明抽样指标和总体指标的误差不超过一定范围的概率保证程度。(√)

4、抽样误差即代表性误差和登记误差,这两种误差都是不可避免的。(×)

5、总体参数区间估计必须具备的三个要素是估计值、抽样误差范围、概率保证程度。(√)

6、在一定条件下,施肥量与收获率是正相关关系。( √ )

7、甲产品产量与单位成本的相关系数是-0.8,乙产品单位成本与利润率的相关系数是-0.95,则乙比甲的相关程度高。( √ )

A、等于 78% B、大于 84% c、在此 76%与 84%之间 D、小于 76%

6、对甲乙两个工厂工人平均工资进行纯随机不重复抽样调查,调查的工人数一样,两工厂工资方差相同,但甲厂工人总数比

乙厂工人总数多一倍,则抽样平均误差( A )。

A、甲厂比乙厂大 B、乙厂比甲厂大 C、两个工厂一样大 D、无法确定

7、反映抽样指标与总体指标之间抽样误差可能范围的指标是(B )。

A、抽样平均误差;B、抽样极限误差;C、抽样误差系数;D、概率度。

8、如果变量 x 和变量 y 之间的相关系数为 1 ,说明两变量之间( D )。

A、不存在相关关系 B、相关程度很低 C、相关程度显著 D、完全相关

9、一般说,当居民的收入减少时,居民的储蓄款也会相应减少,二者之间的关系是( A )。

A、直线相关 B、完全相关 C、非线性相关 D、复相关

10、年劳动生产率 x(千元)和工人工资 y(元)之间的回归方程为 yc=30+60x ,意味着劳动生产率每提高 2 千元时,工人工资平均增

3、解释相关关系的含义,说明相关关系的特点。

时,年利息额 y 与存款额 x 之间就是函数关系,它表现为 y=x×r。而相关关系就没有这样确定的关系了,我们把变量之间 存在的不确定的数量关系称为相关关系(correlation)。比如家庭的储蓄额和家庭收入之间的关系。如果发现家庭储蓄额随 家庭收入的增长而增长,但它们并不是按照一个固定不变的比率变化的,由于可能还会有其他很多较小的因素影响着家庭储 蓄这个变量,因此这其中可能会有高低的偏差,这种关系就是相关关系而不是函数关系。
x 取某一个值时,变量 y 的取值可能有几个。 对这种关系不确定的变量显然不能用函数关系进行描述,但也不是无任何规律可循。通过对大量数据的观察与研究,我们就 会发现许多变量之间确实存在一定的客观规律。 4、请写出计算相关系数的简要公式,说明相关关系的取值范围及其判断标准?

5、拟合回归程 yc=a+bx 有什么前提条件? 在回归方程 yc=a+bx,参数 a,b 的经济含义是什么?

答:1)拟合回归方程

的要求有:1)两变量之间确存在线性相关关系;2)两变量相关的密切程度必须是显著

相关以上;3)找到全适的参数 a,b 使所确定的回归方程达到使实际的 y 值与对应的理论估计值 yc 的离差平方和为最小。

2)a 的经济含义是代表直线的起点值,在数学上称为直线的纵轴截距,它表示 x=0 时 y 常项。 参数 b 称为回归系数,表示自变量增加一个单位时因变量 y 的平均增加值,回归系数 b 正负号可以判断相关方向,当 b>0 时,表示正相关,当 b<0 表示负相关。

五、计算题

1、某企业生产一批零件,随机重复抽取 400 只做使用寿命试验。测试结果平均寿命为 5000 小时,样本标准差为 300 小时, 400 只中发现 10 只不合格。根据以上资料计算平均数的抽样平均误差和成数的抽样平均误差。(学习指导书 P177 第 2 题) 解:1)平均数的抽样平均误差:

,质量指标指数 K p

?

确定同度量因素固定时期的一般方法是: 编制数量指标指数时,应以质量指标为同度量因素,时期固定在基期; 编制质量指标指数时,应以数量指标为同度量因素,时期固定在报告期。 2、综合指数与平均指数有何区别与联系?试列式证明二者之间的关系。 答:平均数指数必须在特定权数的条件下才能成为综合指数的变形。 加权算术平均数指数要成为综合指数的变形,必须在基
期总值( p0q0 )为权数的特定条件下;加权调和平均数指数要成为综合指数的变形,必须在报告期总值( p1q1 )为权数的

3、什么是时期数列和时点数列?二者相比较有什么特点? 写出时期数列和间断时点数列平均发展水平的计算公式。
答:时期数列是指由反映现象在一段时期内发展过程总量的时期指标构成的动态数列。时点数列是指由反映在某一瞬间 总量的时点指标构成的动态数列。二者相比较有以下特点:
(1)时期数列的各指标值具有连续统计的特点,而时点数列各指标值不具有连续统计的特点; (2)时期数列各指标值具有可加性的特点,而时点数列各指标值不能直接相加; (3)时期数列各指标值的大小与所包括的时间长短有直接关系,而时点数列各指标值的大小与时间间隔长短无直接关系。

五、计算题
1、(1)某年我国城市消费品零售额 12389 亿元,比上年增长 28.2%;农村消费品零售额 8209 亿元,增长 24.3%,扣除价格 因素,实际分别增长 13%和 6.8%,试问城乡消费品价格分别上涨多少? (2)某厂 2003 年的产量比 2002 年增长 313.6%,生产费用增加了 12.9%。问该厂 2003 年产品成本的变动情况如何?

解:(1)城镇物价指数: 128.2% ? 113.45% 113%
城镇物价上涨 13.45%,农村物价上涨 16.39%

农村物价指数: 124.3% ? 116.39% 106.8%
