A break off occurs when a respondent enters the online questionnaire but does not complete it. Software allows this abandoned survey data to be captured. Cases which had a break off near the end of the online questionnaire could be included in the dataset.
The bullets below show the point in each questionnaire that respondents must have reached in order for it to count as a partial complete and their answers to be included in the dataset.
These points were chosen because in the case of school year 3-11 pupils and parents it means that they had completed all the participation in sport and activity questions which means that key survey estimates on respondents could be derived:
- Pupils (school year 3-11): PLEnjoy (first question after the activity grid)
- Parents: SwmCan (first question after the activity grid)
- Teachers: ACTTRAV (however, all teacher responses are included in the dataset even if they do not qualify as a partial).
In the final dataset for school year 3-parent, 91.9% (119,862) of the valid cases for analysis are complete and 8.1% (10,586) are partials.
Responses were received from 1,438 teachers and are included in the data even if not meeting the official criteria for a partial shown in the bullets above.
There were 379 schools where pupils or parents responded but no teacher and 67 schools where a teacher response was received but no pupils or parent responses.
The teacher questionnaire was intended to provide contextual school-level information to supplement the pupil-level data.
