Given below are two statements Statement I: In survey research, even a large sample cannot guarantee precision. Statement II: As large samples also do not guarantee precision, the researcher need not worry about sampling error. In light of the above statements, choose the correct answer from the options given below
Statement I is true but Statement II is false
To evaluate the given statements, we need to understand the concept of sampling in survey research.
-
Statement I: In survey research, even a large sample cannot guarantee precision.
This statement is true. While increasing the sample size generally reduces sampling error and increases precision, it does not always guarantee it. Other factors such as sampling bias, measurement errors, and variability within the population can affect the precision of the survey results. Thus, even a large sample size cannot completely eliminate errors in the survey process.
-
Statement II: As large samples also do not guarantee precision, the researcher need not worry about sampling error.
This statement is false. Although large samples cannot guarantee precision, they typically reduce the sampling error. Sampling error is an inherent aspect of survey research that needs to be considered and minimized as much as possible. Ignoring sampling error could lead to incorrect conclusions and unreliable research findings. Hence, researchers should always pay attention to sampling error regardless of the sample size.
Based on the analysis:
- Statement I is true because a large sample size does not ensure complete precision.
- Statement II is false because researchers should always consider sampling error, even with large samples.
Therefore, the correct answer is: Statement I is true but Statement II is false.
