However, we think a nonresponse bias
explanation will only go so far.
As not all consumers provided ratings to survey questions, potential nonresponse bias
should be considered for the consumer rating data at this website.
Although the data were adjusted to minimize nonresponse bias
based on known characteristics of sampled facilities and patients, the possibility of residual nonresponse bias
The work performed under this solicitation involves reviewing and assessing the recent administrations of OJJDP~s National Survey of Children~s Exposure to Violence (NatSCEV) and making recommendations on items that will be included in the survey instrument, frame development, sampling plan, modes of data collection, strategies for reducing nonresponse bias
, reference periods for trend analysis, and viability of supporting various subgroup estimates.
As a pilot assessment, the sample was not adjusted to account for nonresponse bias
If the choice not to participate is not random, this is a nonresponse bias
However, a nonresponse bias
is a concern with this response rate.
Furthermore, the weighting method used for adjustment might not have fully controlled for nonresponse bias
, they said.
05), this suggests nonresponse bias
was not a concern.
Therefore, in the absence of non-responder questionnaires, key constructs can be compared among early and late responses to determine the existence of a nonresponse bias
Two types of bias were of concern and were examined before further analysis was conducted: nonresponse bias
and common method bias.
Previous studies have used comparisons between early and late responders to look at nonresponse bias
(Dooley & Lindner, 2003; Jordan, Walker, Kent, & Inoue, 2011), a method based upon the assumption that late respondents are most similar to nonrespondents (Armstrong & Overton, 1977; Miller & Smith, 1983).
