![]() Data collectors must also take variables into consideration, since results can be skewed by choosing participants who already have certain features in common. Statisticians can also use sampling, which allows them to take a subset of a larger population, choosing to assume that the sample represents the whole. Surveys are often in questionnaire form, with answers varying from multiple choice to open-ended. Before you can decide which statistical tool to use, you must first understand the data being collected.
