Effect, from Latin effectus "performance, accomplishment" can be used in various meanings:

• Any result of another action or circumstance (see pragma, phenomenon, list of effects);
• Cause and effect are the relata of causality;
• In movies and other media, sound effects are artificially created or enhanced sounds;
• In music, an effects unit is commonly used to manipulate the sound of musical instruments (see also: Effects pedal);

• In statistics, effect size is a measure of the strength of the relationship between two variables. Effect size measures are the common currency of meta-analysis studies that summarize the findings from a specific area of research.

Please note that although the word "effect" is most commonly found in noun form, it also exists as a verb, and as such is often confused with the word "affect" (itself most commonly a verb, but occasionally found in noun form, especially in the areas of psychology and philosophy).
