Uncertainty
Uncertainty is the quantitative estimation of error present in data; all measurements contain some uncertainty generated through systematic error and/or random error.
Acknowledging the uncertainty of data is an important component of reporting the results of scientific investigation.
Uncertainty is commonly misunderstood to mean that scientists are not certain of their results, but the term specifies the degree to which scientists are confident in their data.
Careful methodology can reduce uncertainty by correcting for systematic error and minimizing random error. However, uncertainty can never be reduced to zero.

What is syntagmatics?
Semiotics is probably best-known as an approach to textual analysis, and in this form it is characterized by a concern with structural analysis. Structuralist semiotic analysis involves identifying the constituent units in a semiotic system (such as a text or socio-cultural practice) and the structural relationships between them (oppositions, correlations and logical relations).
