1. Sociology and the Sociological Perspective | 社会学与社会学视角

Sociology is the systematic study of human society, social groups, institutions and the relationships between them. It aims to uncover patterns behind everyday life rather than rely on personal opinion or common sense.

社会学是对人类社会、社会群体、制度及其相互关系的系统研究。它旨在揭示日常生活背后的规律，而不是依赖个人观点或常识。

Key concepts include social structure, social action, social order, social control, culture, power and inequality. A sociological perspective asks how individual behaviour is shaped by wider social forces such as class, gender and ethnicity.

核心概念包括社会结构、社会行动、社会秩序、社会控制、文化、权力和不平等。社会学视角探讨个人行为如何受到阶级、性别和族群等更广泛的社会力量影响。

Sociologists distinguish between macro approaches, which study large-scale structures like the economy or the state, and micro approaches, which focus on small-scale interactions and meanings.

社会学家区分宏观方法和微观方法：宏观研究经济或国家等大规模结构，微观则关注小范围互动和意义。

2. Research Methods: Positivism vs Interpretivism | 研究方法：实证主义与解释主义

Positivists argue that sociology should follow the methods of the natural sciences. They favour quantitative data, objectivity and the search for cause-and-effect relationships, treating social facts as measurable things.

实证主义者认为社会学应遵循自然科学方法。他们偏好定量数据、客观性和因果关系研究，将社会事实视为可测量的事物。

Interpretivists, by contrast, argue that human action has meaning. They use qualitative methods such as in-depth interviews and observation to achieve verstehen, or empathetic understanding of actors’ viewpoints.

解释主义者则认为人类行动具有意义。他们使用深度访谈和观察等质性方法，以获得 verstehen，即对行动者观点的移情理解。

In evaluating research, sociologists consider validity, reliability, representativeness and ethics. Primary data are collected first-hand by the researcher, while secondary data already exist, such as official statistics.

在评估研究时，社会学家考虑效度、信度、代表性和研究伦理。一手数据由研究者直接收集，二手数据则已经存在，例如官方统计数据。

3. Key Research Tools and Sampling | 主要研究工具与抽样

Questionnaires can reach large samples quickly and are usually highly reliable, but they may lack depth and validity. Structured interviews use fixed questions, while unstructured interviews allow more flexibility and detail.

问卷可以快速覆盖大量样本，通常信度较高，但可能缺乏深度和效度。结构式访谈使用固定问题，非结构式访谈则提供更多灵活性和细节。

Observation can be participant or non-participant, overt or covert. It often increases validity by studying behaviour in natural settings, but raises ethical issues when covert and can be time-consuming.

观察法可分为参与式或非参与式、公开或隐蔽。它通常通过研究自然环境中的行为提高效度，但隐蔽观察会引发伦理问题且耗时。

Sampling methods include random sampling, stratified sampling, quota sampling and snowball sampling. A sampling frame is a list of the target population from which a sample is drawn; without it, representativeness may be weakened.

抽样方法包括随机抽样、分层抽样、配额抽样和滚雪球抽样。抽样框是抽取样本的目标人群名单；没有抽样框可能削弱代表性。
