Final answer:
The statement that segments applied before sampling won't be sampled is false. Segmentation narrows down the dataset but does not prevent subsequent sampling, which can still affect the segmented data.
Step-by-step explanation:
The assertion that 'because segments are applied before sampling, segment data will not be sampled' is In the context of web analytics and data processing, segmenting refers to dividing a dataset into smaller parts based on certain criteria. Sampling, on the other hand, involves selecting a subset of data from a larger dataset to make statistical inferences about the population. When a segment is applied before sampling, the segment indeed narrows down the dataset, but if sampling is performed afterwards, it can still affect the segmented data. Therefore, even segment data can be subject to sampling, especially in large datasets or when using tools that apply sampling to manage large volumes of data.
