Practical difficulties involved in getting accurate results from telephone survey.

Explanation

Some of the challenges in collecting reliable findings from a telephone survey are as follows:

Coverage is insufficient: Not all individuals in the population have a telephone number on the list, or the number may have changed, thus they are unable to participate in the survey.

Non-response: Calls are frequently not answered by the subject owing to work hours or other reasons, and hence the cases of non-response are higher in telephone surveys.

Problems with the network: Due to network issues, the voice may not be audible at times, or the answer may be misheard, affecting the accuracy of the results.

Interpretation issues: Some questions may have many interpretations, and each respondent may interpret it differently and respond appropriately, impacting the final result's accuracy.
