Appendix 3.3: The questionnaire sample frame and sample
Table A3.1: Details of the sources and procedures used in the construction of sample frames by constituency.
| Constituency | Production of list/ sample frame | Assessment of the sample frame | Sampling technique | Survey technique |
| Curators | The Profiling the Profession survey + CBA Yearbook | The list of individuals obtained was pretty comprehensive | Systematic selection based on a sampling interval with geographical stratification of the list to ensure good coverage | Questionnaires were sent directly to individuals in the sample |
| Contractors | The Profiling the
Profession survey +
CBA Yearbook.
CBA Institutional membership list was also useful. |
These sources provided a pretty comprehensive list of organisations, but not of individuals | Multi-stage sampling was used. First, organisations were sampled in a stratified fashion to ensure good regional coverage. These organisations were asked to provide lists of permanent and temporary staff at all levels of employment. The resulting list of individuals was then sampled systematically using a sampling interval. | Questionnaires were sent directly to individuals in the sample |
| Consultants | The Profiling the Profession survey + CBA Yearbook | It is difficult to know how comprehensive this list is as consultants are a difficult group to identify. There is a strong possibility that the sample frame is partial as consultants are often self-employed or employed by non-archaeological organisations | Systematic selection based on a sampling interval with geographical stratification of the list to ensure good coverage | Questionnaires were sent directly to individuals in the sample |
| Museum archaeologists | The Profiling the
Profession survey +
CBA Yearbook
The Society for Museum Archaeologists Yearbook provided further information |
The list provided reasonable coverage. It may, however, have some bias towards more senior figures when full penetration of the group would be ideal | Systematic selection based on a sampling interval with geographical stratification of the list to ensure good coverage | Questionnaires were sent directly to individuals in the sample |
| Specialists | The Profiling the
Profession survey +
CBA Yearbook.
The list was also supplemented whilst contacting contractors, who were asked to identify any employees undertaking specialist work |
The list of individuals obtained is likely to be partial and difficult to augment as many specialists are self-employed | Systematic selection based on a sampling interval with geographical stratification of the list to ensure good coverage | Questionnaires were sent directly to individuals in the sample |
| University/college staff | The Profiling the Profession survey + CBA Yearbook | The list obtained is pretty comprehensive | Systematic selection based on a sampling interval with geographical stratification of the list to ensure good coverage | Questionnaires were sent directly to individuals in the sample |
| Postgraduates | CBA Yearbook | The source provided a comprehensive list of institutions with postgraduate students in archaeology, but not lists of individuals. | Multi-stage sampling was used. First, institutions were sampled in a stratified fashion to ensure good regional coverage. These organisations were asked to provide lists of permanent and temporary staff at all levels of employment. The resulting list of individuals was then sampled systematically using a sampling interval. | Questionnaires were sent directly to individuals in the sample |
| Undergraduates | CBA Yearbook | The source provided a comprehensive list of institutions with undergraduate students in archaeology, but not lists of individuals | Multi-stage sampling was used. First, institutions were sampled in a stratified fashion to ensure good regional coverage. However, it was not feasible to obtain lists of undergraduate students and questionnaires was distributed by lecturing staff at selected institutions. | Questionnaires mailed to an individual member of staff who distributed them to students. |

Table A 3.11: Details of the sample frame and interval used for local/regional societies
NB. A slightly different sampling strategy has been adopted here as it was not possible to obtain a list of individuals and their addresses. Instead, 3 copies of the questionnaire were sent to the named representative of each society, along with a letter asking that person to complete 1 and pass the others on to 2 other members, preferably amateur members rather than professionals who should have been included in the sample frame elsewhere. In addition, one society from each region was contacted directly by telephone to ask them if they could distribute 10 questionnaires to their members for us to ensure that a reasonable sample was obtained. A list of those organisations follows, along with a table showing the maximum number of individuals sampled for each region. The sample size appears much larger than for other constituencies, but it is likely that in many cases the named representative may not have been able/willing to pass questionnaires on to their members.
Those societies who agreed to distribute 10 copies include:
| Region | Sample frame (societies) | Sampling interval | Number sampled |
| Central England | 40 | 1/1 | 120 (127) |
| Channel Isles | 1 | 1/1 | 3 |
| Isle of Man | 1 | 1/1 | 3 |
| Northern England | 18 | 1/1 | 54 (61) |
| Northern Ireland | 1 | 1/1 | 3 (10) |
| Republic of Ireland | 2 | 1/1 | 6 (13) |
| Scotland | 11 | 1/1 | 33 (40) |
| Southern England | 41 | 1/1 | 123 (130) |
| Wales | 7 | 1/1 | 21 (28) |
| Total | 122 | - | 366 (409) |
NB. The total number sampled rises to 409 when those the additional copies sent to those societies listed above are included.
Table A3.12: Details of the sample frame and interval used for national societies
The sampling strategy for national societies also differed. Many people in other constituencies were likely to be members of national societies aside from their primary constituency so the sampling strategy focused on named the named representative of each society. National societies include all nation-wide societies whether, including period and subject specific societies, for example the Lithic Studies Group.
| Region | Sample frame | Sampling interval | Number sampled |
| Central England | 13 | 1/1 | 13 |
| Channel Isles | - | 1/1 | 1 |
| Isle of Man | - | 1/1 | 1 |
| Northern England | 3 | 1/1 | 3 |
| Northern Ireland | 0 | 1/1 | 0 |
| Republic of Ireland | 7 | 1/1 | 7 |
| Scotland | 3 | 1/1 | 3 |
| Southern England | 31 | 1/1 | 31 |
| Wales | 2 | 1/1 | 2 |
| Total | 59 | - | 59 |
Details of the sample frame and interval used for independent archaeologists
The sample of Independent archaeologists was based on the Council for Independent Archaeology membership list. Circulation was arranged through the CIA and 400 questionnaires were distributed. As with local archaeology societies, the sample size appears much larger than for other constituencies, but as there was no means of tracking responses and sending reminders the response rate was expected to be lower and consequently it was necessary to send more out.
Details of the sample frame and interval used for undergraduates
It was not possible to obtain lists of named undergraduates so sampling was based on the selection of one University in each region. The questionnaires were then distributed by a member of staff their students. The Universities selected were:
University of Leicester (30)
University of Sheffield (30)
Queen's University, Belfast (20)
University of Southampton (40)
University College, Dublin (40)
University College of Wales, Lampeter (30)
University of Glasgow (20)
Total: (210)
