Extract of sample "Applying Sampling Strategies"

In research, there are biases that result due to the sampling method. Sampling bias may be due self-selection by the research or under-coverage during the sampling time. Survivorship bias may also occur during the sampling. Despite the type, biases make sample non-representatives of the entire original population. However, there are various methods employed in research that help researchers reduce sampling bias. Random sampling helps researchers develop representative samples by reducing both response bias and bias due to under-coverage.

Therefore, it is important to conduct random sampling especially if the sampling method is based on probability. Poor measurement processes during research may also result in bias. Errors in measurement always lead to response biases in research. Precision and care are encouraged during the measuring process to reduce such kind of bias. The other important method to reduce sampling bias is to use a large sample size. Large sample size does not affect the overall survey but helps reduce bias by making the sample statistic less variable (Tuckett, 2004).
