A hole count is requested from the Raw data view window.
This shows a summary count of the raw data file. It is called a "hole count" because originally it would have been a count of the holes in binary data punched cards.
If the raw data structure is "Multiple lines per questionnaire", then the hole count should be produced after collating.
For each data location (column) it shows the count of the number of lines that contain:
•Blank or empty
•Any contents
•Any digit 0 to 9
•Any letter A to Z
•Other contents (not a digit or letter)
It also shows the number of lines with particular codes in each data location:
•Code V (for character data this is ampersand "&")
•Code X (for character data this is minus "-")
•Code 0
•Code 1
•Code 2
•Code 3
•Code 4
•Code 5
•Code 6
•Code 7
•Code 8
•Code 9
For character data only, one of these can be present in each. For example, to be counted as code 3 the column must contain the digit "3”.
For binary data each column can contain up to 12 codes, so a line can appear in more than one row. Letters and symbols are also represented as codes and will be shown.
For binary data one further count is shown:
•Multi (those with more than 1 of the 12 codes in this column)
A hole count can be copied to the clipboard for pasting into a spreadsheet program.
A hole count can also be printed and there is a facility to reduce the font size for large files where the figures may not fit on the page.
