The phrase "an observer study" is not correct in English; it should be "an observational study." You can use it when referring to a type of research design where the researcher observes subjects without manipulating any variables.
Example: "In this research, we conducted an observational study to analyze the effects of diet on health outcomes."
Alternatives: "a monitoring study" or "a watching study."
The Times Educational Supplement's survey in September of more than 2,000 teachers found about 20% considered their classrooms unsuitable to teach in, with two-thirds saying their school's infrastructure was outdated, while an Observer study of headteachers in May found almost 40% saying their buildings were not fit for purpose.
The paper said that the legislators had relied on 1990 population figures to accomplish their task but that an Observer study of voter registration figures for 1990-98 indicathatthet the district was now probably only 55percentt Democratic and, therefore, probably less than 33percentt black.
The global noise level was further compared with image noise values from clinical patient CT images obtained by an observer study.
The goodness of fit of the models was assessed using the coefficient of determination (R(2)) and the visual appearance of the hybrid images was assessed with an observer study using images of both real and simulated lesions and receiver operator characteristic (ROC) analysis.
Image quality of the coronary CT angiograms at low doses is obviously affected by noise; the influence of noise on the clinical diagnosis is now being studied in an observer study.
In a previous study by this group, Kendall's tau- b for interobserver agreement for HER2 in an observer study of 241 regions of interest read by 7 pathologists was 0.61 (95% CI: 0.53 0.67) [ 40].
I argue for the first requirement, and then ask what would be needed to satisfy this requirement, and what would be the corresponding behavior so that an observer studying the apes would say, "yes, this is quite plausible, these are apes that seem to live up to this requirement".
It is noted that in a previous experiment using a similar observer study design and dataset no significant improvement with traditional CAD prompting was found when readers had limited training [ 23].

A human observer study was performed on a subset of the simulated tomosynthesis images, confirming the detection performance trends with respect to density and serving as a validation of the implemented detector.
A human observer study was designed to assess the detection performance of A-MAP versus post-smoothed maximum-likelihood (ML) reconstruction.
