1. Consensus and Conflict Theory Equations | 共识与冲突理论方程
Durkheim' feel connected through collective conscience, society remains stable. Parsons later added that value consensus functions like a social glue, binding institutions together.
涂尔干的共识方程可以概括为：共享规范 + 社会整合 = 社会秩序。当个体通过集体意识彼此联结时，社会保持稳定。帕森斯后来补充说，价值共识就像社会黏合剂，把各种制度联结在一起。
urgeoisie owns the means of production, while the proletariat sells labour. This fundamental conflict inevitably generates class consciousness and revolution.
与此相对，马克思主义冲突定理表述为：阶级矛盾 + 剥削 = 社会变革。资产阶级拥有生产资料，无产阶级出卖劳动力。这一根本冲突必然催生阶级意识与革命。
2. The Functionalist Formula for Family | 功能主义家庭公式
+ Educational Functions. When all four are met, the family ensures social stability and the continuation of society.
根据默多克的观点，核心家庭承担四项基本功能。他的公式为：核心家庭 = 性功能 + 生殖功能 + 经济功能 + 教育功能。当四项功能全都满足时，家庭便确保了社会稳定与社会延续。
Parsons’ 'warm bath' ern industrial society, the family relieves stress by providing emotional support, allowing adults to return to work refreshed.
帕森斯的“暖水浴”理论给出了另一个定理：工具性角色（男性） + 表达性角色（女性） = 家庭稳定。在现代工业社会，家庭通过提供情感支持缓解压力，让成年人能够精神焕发地重返工作。
3. Marxist Theorem of Education | 马克思主义教育定理
ion of a Submissive Labour Force. Schools mirror the capitalist workplace by rewarding obedience and punishing creativity, thereby maintaining ruling‑class domination.
鲍尔斯和金蒂斯提出了对应原理，可写作：等级制学校结构 + 隐性课程 = 驯服劳动力的再生产。学校通过奖励服从、惩罚创造力来复刻资本主义的工作场所，从而维持统治阶级的主导地位。
orem adds: Education = Ideological Conditioning. The education system transmits the ruling‑class ideology as if it were common sense, persuading working‑class pupils to accept their subordinate position.
阿尔都塞的意识形态国家机器定理补充道：教育 = 意识形态训导。教育系统将统治阶级的意识形态当作常识来传递，说服工人阶级学生接受自身从属的位置。
4. The Labelling Theory Hypothesis | 标签理论假设
eviant, the individual may internalise the label, leading to a deviant career. The theorem states: Label × Master Status = Deviant Identity.
贝克尔的标签假设遵循一个序列逻辑：初级偏差 + 社会反应 = 次级偏差。某个行为一旦被贴上越轨标签，个体便可能内化该标签，从而走向越轨生涯。其定理表述为：标签 × 主要地位 = 越轨身份。
ore, the amplification spiral is: Negative Label → Stigma → Exclusion → Stronger Deviance.
勒默特对此进行了扩展：社会反应不仅是反应，更是后续越轨的原因。因此，标签放大螺旋为：负面标签 → 污名 → 排斥 → 更强烈的越轨。
5. Social Stratification Equation | 社会分层方程
tification. Unlike Marx, Weber argued that stratification is not only about ownership of property but also about prestige and party influence.
韦伯关于分层的多维度观点可表达为：阶级（经济） + 地位（社会荣誉） + 权力（政治） = 社会分层。与马克思不同，韦伯认为分层不仅仅关乎财产所有权，还关乎声望与党派影响力。
The functionalist Davis– ation for the most talented to fill functionally important positions. Society allocates higher income and status to positions requiring scarce skills, ensuring that key roles are filled competently.
功能主义的戴维斯-穆尔命题提出了一个分层定理：不平等回报 = 激励最有才能者承担功能重要的位置。社会将较高的收入和地位分配给需要稀缺技能的角色，以确保关键职位得到胜任。
6. Crime Rate Formula | 犯罪率公式
To compare crime levels across areas, sociologists use the crime rate per 1,000 population. The standard formula is:
为比较不同地区的犯罪水平，社会学家使用每千人口犯罪率。标准公式为：
Crime Rate = (Recorded Offences ÷ Total Population) × 1,000
This formula reveals the intensity of crime independent of population size. A rise in recorded crime may reflect increased reporting rather than actual crime growth, a point examined through the social construction of crime statistics.
该公式揭示了不受人口规模影响的犯罪强度。记录在案的犯罪数量上升可能反映的是报案率提高而非实际犯罪增长，这一点需要借助犯罪统计的社会建构加以审视。
7. Measures of Central Tendency | 集中趋势量数
Researchers summarise data using mean, median and mode. Their mathematical notations are:
研究者用平均数、中位数和众数来概括数据。它们的数学表示是：
Mean = (Σx) ÷ n
Median = middle value when data are ordered
Mode = most frequently occurring value
In sociology, the mean is sensitive to extreme scores, so the median is often preferred when reporting income or wealth, as a few billionaires can dramatically raise the mean without representing the typical experience.
在社会学中，平均数对极端数值敏感，因此在报告收入或财富时常用中位数，因为少数亿万富翁可能大幅拉高平均数，却无法代表典型经历。
8. The Standard Deviation Theorem | 标准差定理
dard deviation measures the spread of data around the mean. Its formula is: SD = √(Σ(x - x̄ ndicates that values cluster tightly around the average; a high SD signals wide inequality—for instance, in the distribution of educational attainment or household income.
标准差衡量数据围绕平均数的离散程度。公式为：SD = √(Σ(x - x̄)² ÷ n)。标准差较小表明数值紧密聚集在平均数周围；标准差较大则意味着广泛的不平等，例如在教育成就或家庭收入分布中。
This 'theorem' of dispersion helps sociologists test hypotheses: if two schools have the same mean GCSE score but different SDs, the one with the larger SD displays greater internal variation, possibly pointing to within‑school setting or streaming effects.
这一离散“定理”有助于社会学家检验假设：若两所学校GCSE平均分相同但标准差不同，标准差较大的学校内部差异更显著，可能指向校内分班或分层教学的影响。
9. Sampling Error Formula | 抽样误差公式
mple rather than the whole population, researchers calculate the margin of error. For a 95% confidence level, the approximate formula is: Sampling Error = (1.96 × SD) ÷ √n, where n is sample size. A larger n reduces sampling error, making results more representative.
当使用样本而非总体时，研究者会计算误差幅度。在95%置信水平下，近似公式为：抽样误差 = (1.96 × SD) ÷ √n，其中n为样本量。n越大，抽样误差越小，结果更具代表性。
Eduqas students should remember that probability sampling (simple random, stratified) allows such calculations, whereas non‑probability sampling (snowball, quota) does not, limiting the generalisability of findings.
Eduqas考生应牢记，概率抽样（简单随机、分层）允许此类计算，而非概率抽样（滚雪球、配额）则无法如此，从而限制了研究结论的可推广性。
10. Correlation and Causation Law | 相关与因果律
direction of a relationship between two variables. Its conceptual formula is: r = Σ((x - x̄)(y - ȳ inear relationship, but the fundamental law remains: Correlation does not imply causation.
相关系数r指示两个变量之间关系的强度与方向。其概念公式为：r = Σ((x - x̄)(y - ȳ)) ÷ ((n-1)SDx SDy)。r接近+1或-1意味着强线性关系，但基本法则仍是：相关不蕴含因果。
For instance, ice‑cream sales and crime rates may be positively correlated because both increase in hot weather. Recognising this 'third variable problem' is essential when evaluating sociological research on topics like poverty and educational underachievement.
例如，冰淇淋销量与犯罪率可能正相关，因为两者都在炎热天气里上升。认识到这一“第三变量问题”对于评价贫困与教育成绩低下等社会学研究至关重要。
11. The Poverty Line Equation | 贫困线方程
Relative poverty is defined by the government’s key threshold: Household income below 60% .6. Families with income falling below this line are considered to be in relative poverty.
相对贫困由政府的关键门槛定义：家庭收入低于中位数的60%。由此得到贫困线方程：贫困门槛 = 家庭收入中位数 × 0.6。收入落于此线以下的家庭被视为处于相对贫困。
Townsend’s theorem of relative deprivation deepens this: individuals are poor when they lack resources to participate in customary activities. Thus, poverty is not simply low income but exclusion from the ordinary living patterns of society.
汤森的剥夺定理对此加以深化：当个体因缺少资源而无法参与惯常活动时，他们就是贫困的。因此，贫困不仅仅是低收入，而是被排斥在社会正常生活模式之外。
12. Social Mobility Index | 社会流动指数
its a high mobility rate; a rigid one shows low fluidity between origins and destinations.
代际流动常表达为：流动率 = (改变阶级的人数 ÷ 总体样本数) × 100。开放社会表现出高流动率；僵化社会则在出身与归宿之间展示出较低的流动性。
The Oxford Mobility Study by Goldthorpe provided both absolute and relative mobility rates, revealing that while absolute mobility increased, relative mobility—the chances of moving up or down compared to others from different backgrounds—remained unequal. This formula helps assess the openness of the stratification system.
戈德索普的牛津流动研究提供了绝对与相对流动率，揭示出尽管绝对流动有所增加，相对流动——与不同出身的他人相比向上或向下移动的机会——依然不平等。这一公式有助于评估分层体系的开放程度。
