Estimation vs. Projection — What's the Difference?

Estimation (or estimating) is the process of finding an estimate, or approximation, which is a value that is usable for some purpose even if input data may be incomplete, uncertain, or unstable. The value is nonetheless usable because it is derived from the best information available.

(psychology) A belief or assumption that others have similar thoughts and experiences to one's own. This includes making accusations that would more fittingly apply to the accuser.

The act or an instance of estimating

The act of projecting or the condition of being projected.

The amount, extent, position, size, or value reached in an estimate

A thing or part that extends outward beyond a prevailing line or surface

An opinion or judgment

A plan for an anticipated course of action

Favorable regard; esteem

A prediction or estimate of something in the future, based on present data or trends.

The process of making an estimate.

The process of projecting an image onto a screen or other surface for viewing.

The amount, extent, position, size, or value reached in an estimate.

An image so projected.

Esteem or favourable regard.

(Mathematics) The image of a geometric figure reproduced on a line, plane, or surface.

The act of estimating.

A system of intersecting lines, such as the grid of a map, on which part or all of the globe or another spherical surface is represented as a plane surface.

An opinion or judgment of the worth, extent, or quantity of anything, formed without using precise data; valuation; as, estimations of distance, magnitude, amount, or moral qualities.

(Psychology) The attribution of one's own attitudes, feelings, or suppositions to others, thought in psychoanalytic theory to be an unconscious defense against anxiety or guilt.

Favorable opinion; esteem; regard; honor.

Something which projects, protrudes, juts out, sticks out, or stands out.

Supposition; conjecture.

The action of projecting or throwing or propelling something.

An approximate calculation of quantity or degree or worth;

(archaic) The throwing of materials into a crucible, hence the transmutation of metals.

A document appraising the value of something (as for insurance or taxation)

(archaic) The crisis or decisive point of any process, especially a culinary process.

The respect with which a person is held;

The display of an image by devices such as movie projector, video projector, overhead projector or slide projector.

A judgment of the qualities of something or somebody;

A forecast or prognosis obtained by extrapolation

(photography) The image that a translucent object casts onto another object.

(cartography) Any of several systems of intersecting lines that allow the curved surface of the earth to be represented on a flat surface. The set of mathematics used to calculate coordinate positions.

(geometry) An image of an object on a surface of fewer dimensions.

(linear algebra) An idempotent linear transformation which maps vectors from a vector space onto a subspace.

(mathematics) A transformation which extracts a fragment of a mathematical object.

(category theory) A morphism from a categorical product to one of its (two) components.

(grammar) The preservation of the properties of lexical items while generating the phrase structure of a sentence. See Projection principle.

The act of throwing or shooting forward.

A jutting out; also, a part jutting out, as of a building; an extension beyond something else.

The act of scheming or planning; also, that which is planned; contrivance; design; plan.

The representation of something; delineation; plan; especially, the representation of any object on a perspective plane, or such a delineation as would result were the chief points of the object thrown forward upon the plane, each in the direction of a line drawn through it from a given point of sight, or central point; as, the projection of a sphere. The several kinds of projection differ according to the assumed point of sight and plane of projection in each.

Any method of representing the surface of the earth upon a plane.

A prediction made by extrapolating from past observations

The projection of an image from a film onto a screen

A planned undertaking

Any structure that branches out from a central support

Any solid convex shape that juts out from something

(psychiatry) a defense mechanism by which your own traits and emotions are attributed to someone else

The acoustic phenomenon that gives sound a penetrating quality;

The representation of a figure or solid on a plane as it would look from a particular direction

The act of projecting out from something

The act of expelling or projecting or ejecting
