A representative sample is necessary for accurate reflection of the study population. This means that the sample is selected in a way that each member of the population has an equal chance of being included in the sample, and that the demographics and characteristics of the sample closely match those of the larger population. The size of the sample depends on the study design and goals, and it does not need to be very large in order to be representative. Publicity and standardization are not factors that necessarily ensure representativeness.
