The survey was sent to 40 high school students. Among 40 students, 34 students responded in the survey and 6 students did not respond in the survey.
Nonsampling errors occur due to the undercoverage, bias due to nonresponse, bias due to response, and data entry error.
In the study, only 40 students were taken into consideration. As all the students of high school were not surveyed, there is an error due to undercoverage.
As six students did not respond in the survey, there is an error due to nonresponse. The response error also exists in the study because all the students are not from the same class.
The response rate is 85%.
A reminder mail can be sent to the students who did not respond earlier.
