Sense Data
Sense data refers to the raw information our senses gather from the world, such as colors, sounds, tastes, and textures. It's an immediate experience before our brain interprets it. For example, when you see a red apple, the sense data includes the color red and the shape of the apple. Qualia are the subjective qualities of these experiences, like the specific "redness" you perceive. The distinction highlights that while we can discuss the facts about things, the personal experience of those facts—how they feel or appear to us—can vary greatly from one person to another.

Sense-data refers to the immediate sensations we experience through our senses, such as colors, sounds, and textures. In philosophy, particularly in the study of perception, sense-data are considered the mental representations or experiences that arise when we perceive the world around us. For example, when you see a red apple, the 'redness' and 'roundness' you perceive are the sense-data your mind creates based on sensory input. Philosophers debate whether sense-data represent the external world accurately or if they are subjective experiences shaped by our minds.
