German term or phrase:Feldbelegungen
Bei diesem Beispiel ist N=312. Dieses N wird keineswegs in allen Fragen erreicht. Aber schon bei N=312 liegen teilweise so geringe Feldbelegungen vor, dass Korrelationsanalysen, Chi-Quadrat-Analysen keine validen Befunde ergeben können.
This one has stumped me in an otherwise pretty straightforward text.
Explanation: you don't tell us what kind of statistical analysis is being conducted here, but the use of the chi-square test implies that we may be talking about results in the form of a contingency table. If so, the 'Felder' within the table are referred to as 'cells' and the value within the cell is the cell 'frequency'.
'Distribution' would be more relevant in graphical statistical analyses, but I'm not sure that 'Feld' would then make much sense: how are the boundaries of these 'Felder' within the graph defined?
'The observed cell frequencies are organized in rows and columns like a spreadsheet. This table of observed cell frequencies is called a contingency table, and the chi-square test if part of a contingency table analysis' http://www.statpac.com/statistics-calculator/counts.htm
'A key assumption of the Chi Square test of independence is that each subject contributes data to only one cell. Therefore the sum of all cell frequencies in the table must be the same as the number of subjects in the experiment.' http://psych.rice.edu/online_stat/chapter13/contingency.html
Thanks, Kieran. I think this is what I was looking for. As you correctly pointed out, the text deals with results organized in a contingency table (i.e. in rows and columns). The problem in the study is that some of the cells have such 'low frequencies' (e.g. only one respondent of a certain ethnic background in a particular location) that an analysis would not produce particularly useful results.
Thanks also to all the others for your responses. 4 KudoZ points were awarded for this answer
Thanks, Harry. Not sure though if that's what is meant! :-(
As I understand it, 'Feldbelegungen' refers to the 'occurence' of specific data in a 'field', i.e. if/how the field (e.g. in a graph) is 'belegt'.
Explanation: fields that have numbers, variables, values, etc.
**********************************************************************
Feld : field, array, matrix
[Definition(1)]the physical quantity defined at all points in a region.By extension,the region in which the distribution exists
[Definition(2)]the spatial distribution of a phenomenon to which numbers and/or quantities can be assigned

some explanation: the reliability of statistical calculations lies in numbers (and the integrity of the calculator ;-P)
the required terminology here depends on your definition of 'sample': I used it in the meaning of a specific data point ('Feld') - the population (number of items) of each data point should be high enough; in 'sample distribution' it's used in the meaning of a subset ('N') of the total group in question and how the results are ditributed over possible data points ('Feld')
IMO the source text refers to Feld = sample, so Feldbelegungen = sample populations, and sample distribution would have possibly been something like Feldverteilung

The updates to the menu were made to make the site easy and more intuitive for visitors. Obviously, like any change, this may take a few days to get used to.
The dropdown menus have been divided into two-dimensional panels with similar items grouped together under headings. This eliminates scrolling for those with smaller screens, and also improves readability.
Mouseover your name at the top of the screen. Here you will find information about your account, your email settings, and more. The "My ProZ.com" menu was moved up here to simplify the main navigation, and to keep all of this type of information together.
