Meaning, scope and relevance of Social Science

Under the stated rule, ₹19,900 qualifies because it is below ₹20,000, while ₹20,100 does not. A strict eligibility threshold can therefore treat households differently even when their incomes are close.

A central facility may serve many users at lower average cost, yet create access difficulties for distant residents. Public planning must consider both efficient service delivery and the distribution of access.

Wetlands can provide ecological functions and support human livelihoods. Land conversion may affect several groups differently, so Social Science examines environmental changes together with their economic and social consequences.

Direct employment occurs within the factory. Indirect employment arises through suppliers, while induced employment can result when workers spend their earnings on other goods and services. These categories describe different pathways of economic influence.

Survey comparisons require questions to convey equivalent meanings across languages. A stronger expression may change how respondents interpret the scale, making results less comparable.

When nonresponse is related to the variable being measured, respondents may not represent the population accurately. Underrepresentation of high-income households can reduce the observed mean income.

Village A improves by 15 percentage points, and Village B improves by 10 percentage points. The difference-in-differences estimate is 15 minus 10, or 5 percentage points. Interpreting this as a causal effect requires assumptions, including comparable trends without the programme.

Group-level turnout and population composition do not reveal exactly which individuals voted. Drawing conclusions about individual behaviour from neighbourhood averages risks an ecological inference error.

A proposed cause must occur before the effect attributed to it. A decline beginning before the centre opened cannot be explained by its opening, although the centre might influence subsequent changes.

A mediating factor helps explain how an intervention influences an outcome. In this case, the scholarship may reduce financial barriers, which can then support attendance.

When missingness depends on the unreported value, the observed responses can systematically differ from the full population. The average calculated from available answers may therefore underestimate debt.

Relationships observed between areas need not match relationships between individuals within those areas. Differences in aggregation and local conditions can change the strength of statistical associations.

Public street lighting is generally difficult to restrict to individual contributors, and one person's benefit does not usually prevent others from benefiting. This can create a free-rider problem in voluntary funding.

Demand and production costs influence businesses through different mechanisms. Examining sales, prices and costs over time can help assess their relative contributions, including whether both factors were involved.

Intergenerational occupational mobility concerns movement between occupational positions across generations. Linked parent-child information allows researchers to examine these transitions directly.

The direction of causation may run from poor health to greater hospital use rather than the reverse. Researchers must consider reverse causality before interpreting an observed association.

A communication network can become more valuable to each user when more relevant people participate. Greater membership creates additional possible connections, although actual usefulness also depends on how the application functions.

The selection rule omits all households above the threshold. The resulting average describes the restricted group, not the full town population, and is likely to underestimate the townwide mean if higher incomes are present.

The plans differ in overall coverage and distributional effects. Comparing efficiency alongside who gains access makes the trade-off explicit without treating one measure as sufficient.

When both measures come from the same method and setting, response styles or wording can contribute to their correlation. Researchers should consider common-method bias alongside genuine relationships.

Cultural diffusion occurs when ideas or practices spread between groups. Receiving communities may adapt new elements while preserving existing traditions, producing cultural change without complete replacement.

Funding is targeted toward schools already performing poorly, so their low results may precede increased spending. This creates endogeneity and makes a simple comparison unsuitable for estimating funding's causal effect.

Robustness checks examine whether a finding depends heavily on one particular measurement or analytical choice. Consistent findings across reasonable alternatives can increase confidence, although they do not alone establish causation.

A comparison group is less informative when it receives some benefits indirectly from the intervention. These spillover effects can reduce the observed difference between treated and untreated groups.

Entrepreneurship depends not only on skills but also on access to finance, institutions and markets. Unequal access to affordable credit can create different opportunities for similarly capable individuals.
