kebolehjadian

Kebolehjadian is a Malay term describing the degree to which a specified outcome is likely to occur under given conditions. In English-language contexts it is often translated as likelihood or probability and is used in statistics, risk assessment, project planning, and policy analysis within Malay-speaking settings.

Etymology and nuance: The word combines boleh (able) with jadi (to happen), with keb- forming an abstract noun. Kebolehjadian conveys the state or quality of something being possible or expected, and it is distinct from related terms such as kemungkinanan (possibility) or kebolehan (ability). In practice, kebolehjadian emphasizes the likelihood of an event rather than mere feasibility or capability.

Measurement and interpretation: Kebolehjadian can be described qualitatively (high, moderate, low) or quantitatively as a probability value from 0 to 1 (or a percentage). Methods to estimate it include probability models, historical data, expert elicitation, Bayesian inference, scenario analysis, and risk scoring. The term is commonly used when assessing risks, forecasting outcomes, or evaluating plans under uncertainty.

Contexts and examples: It appears in fields such as meteorology, epidemiology, finance, and engineering, where stakeholders must judge how likely certain events are. For example: kebolehjadian kejayaan projek itu dianggarkan 70 peratus. The concept supports prioritization and decision-making by focusing on expected results under specified assumptions.
