Undergraduates were also asked to confirm their scenario at the end of the survey to allow the researcher to remove responses from undergraduates who might have forgotten their scenario midsurvey.
Pyrrole mineralization in aqueous solution was examined with multiple responses such as chemical oxygen demand (COD) (response, Y1) and specific energy consumption (SEC) in kWh/kg of COD removed (response, Y2).
The results depend on the quality of the removed response options.
Before we began our analysis we conditioned our data by removing responses from the participants who did not complete all surveys, forward coded reverse phrased items, and removed duplicated answers from the same users.
A total of 65 studies were identified once we removed responses that did not meet our study criteria.
After removing responses in which the instructor they were referring to was indeterminable (e.g., "They are more understanding"), 127 respondents remained for analysis.
Data were then filtered by removing responses that conveyed no information about the health of the participant (e.g., "No," "N/A," "I have nothing to say").
To obtain responses to each of the 16 possible switches (i.e. the pairs of 4 different stimulus types: V, H, VH, and B (blank)), we first removed responses unspecific to switch type by pixel-wise subtraction of the average response across the entire stimulus sequences.
The demographic variables like gender, age, educational background, service period of employee, position level in an office and task assignment were taken into account to remove any response bias, and then the survey was conducted after calling every respondent.
Removing the flag doesn't remove the response to its call.
