limitations of tabulation of data

In Sweden (see Selander et al., 1998; Wallgren and Wallgren, 1999), for crops with subsidies based on area and for other crops which are generally cultivated by the same farms, the bias is low, but for other crops the downward bias can be about 20%. It saves time as well as space. On the one hand, this relevance should guarantee accurate answers and high quality of data; on the other, specific interests of respondents can generate biased answers. Tabulation helps in drawing the inference from the statistical figures. 12. Tabulation helps in drawing the inference from the statistical figures.

Limitations of the Current Tabulation There are many regimes of Z and E where most recent tabulations are in agreement at the 5% level, particularly well away from edges in the 5-40 keV range, in lower Z elements, and in f″ or µ PE tabulations. Last Updated on Fri, 04 Sep 2020 | Agricultural Statistics. There will be two sources of limitation: Logical sources; Model sources; The logical sources are relevant for any inference and would therefore apply equally for crosstabulation and correlation analyses: The presense of correlation (including negative correlation) does not necessarily indicate causation. ...

They do not contain details. It involves the orderly and systematic presentation of numerical data in a form designed to explain the problem under consideration. The most critical point, when using administrative data for statistical purposes, is that their characteristics can change from one year to the next depending on their aims and without regard to statistical issues.
