Answer:
There is nonresponse bias. The results could be biased because the small percentage who chose to return the survey might be very different from the majority who did not return the survey.
Explanation:
Introduces a given conditional bias model. Only 10% of teachers responded to the survey, but the remaining 90% of teachers refused to participate in the survey.
This creates unresponsive bias in the model. If the remaining 90% of teachers respond, there may be a chance of a vocal outcome. This is why the model introduced unresponsive bias
Therefore, the negative finding of this report is dismissed.
