Question
A data analyst is collecting data. They decide to gather lots of data to make sure that a few unusual responses do not skew the results later in the process. What element of data collection does this describe?
Solution
This describes the element of data collection known as "Sample Size". The sample size refers to the number of observations or individuals in any statistical setting. In this case, the data analyst is collecting a large amount of data (large sample size) to ensure that a few unusual responses do not skew the results. This is because, in a large sample, individual observations have less of an impact on the overall results. Therefore, even if there are some unusual or extreme values, they will not significantly affect the overall findings.
