Furthermore, self-selection bias in this study is to some extent mitigated by high rates of completion for our survey, and information about panelists who elect not to complete the survey informs us about potential differences between those who chose to participate and those who declined.
Last year, NPD phased out the last of the paper diaries in use since the 1950's and now receives all information from panelists via the Internet.
Prior information on the panelists was used to determine eligibility and to draw a stratified random sample with oversampling of panelists with low response rates.
The items were constructed as open-ended questions and the document was used for soliciting information from the panelists.
The dataset also contains information about the panelists' socio-economic characteristics spanning from income, location, type of family and number of household membersq.
Resonate adds information about each panelist from other sources, including voting and campaign contribution history and demographic information, collecting about 1,100 pieces of data per panelist.
(This section has been updated to reflect new information from a panelist who was present).
These materials were supplemented by information brought by the panelists.
We had hoped that, on the basis of the information conveyed by the panelists, the students would realize that a career built upon graduate research training in STEM would be compatible with having a family; that is, it would not be easier or more difficult than if they were in other professions that were also based on advanced degrees.
Using this information as a guide, panelists were asked to score the overall impact of each study, independently, using hand held keypad transmitters.> The results from the panel were analyzed by examining the distribution of scores as group means and standard deviations for each question, as well as a measure of spread of responses (coefficient of variation, standard deviation/mean).
