Document Summary
Common sense can outperform statistics in several ways such as recognizing patterns (handwriting, human language, etc. ) than computer programs based on statistics. In other cases, statistics can outperform common sense in other ways that require relevant information found beyond what can be accessible or is less vivid than what can be perceived with our senses such as personal and impersonal information. Descriptive statistics provides a description of specific groups (statistical data) to describe these groups as a whole picture. Inferential statistics, having the same purpose as descriptive statistics, looks beyond the given data (hypothesizing and probabilities) to shape possibilities. Absolute zero: there are no values below zero. Equal interval: constant measurement for whatever scale used (meters, mass, liters). Fixed order: sequential unity where figures have rankings (e. g. 5 > 4 > 3) Functional unity: specifies a certain domain within a specific context (weight and height). Distinctions: ratio scale has an absolute zero.
