The word "subsample" is spelled as [ˈsʌbˌsæmpl]. The initial "sub-" is pronounced with the unstressed "uh" sound ([ˈsʌb]), which is followed by the stressed vowel "a" pronounced as the "æ" sound ([ˈsʌbˌsæm]). Lastly, the final syllable "-ple" is pronounced with the "uh" and "l" sounds ([ˈsʌbˌsæmpl]). To create a subsample means to randomly select a subset from a larger sample, often used in scientific research to reduce data and increase efficiency.
A subsample refers to a smaller representative subset of a larger group, population, or data set that is selected for analysis or a particular research purpose. It involves selecting and collecting a portion of the original sample or data, which is considered to be an unbiased representation of the whole.
Subsampling is commonly employed in various fields such as statistics, research, and sampling techniques to reduce the time, cost, or resources required to analyze the entire population or dataset. By selecting a subsample, researchers aim to obtain valid and reliable conclusions without having to examine the entire data.
The process of subsampling typically involves randomly selecting participants, observations, or data points from the original sample or dataset, ensuring that each element has an equal chance of being included. This method allows for the reduction of unnecessary or redundant information and helps in increasing the overall efficiency of the analysis.
Subsamples can be used for various purposes, such as testing hypotheses, estimating population parameters, or drawing inferences about the entire population. The effectiveness of a subsample depends on its representativeness, meaning that it should accurately reflect the characteristics of the entire group or population being studied.
Overall, subsampling plays a crucial role in research and statistical analysis by providing a more manageable and cost-effective approach to studying and drawing conclusions from large datasets or populations.
The word "subsample" is derived from the combination of two words: "sub-" and "sample".
The prefix "sub-" in English is derived from the Latin prefix "sub", meaning "under" or "below". It is commonly used to indicate something that is below, secondary, or smaller than the main thing.
The word "sample" comes from the Old French word "essample", which means "example" or "pattern". Its root can be traced back to the Latin word "exemplum", meaning "a sample" or "a model".
Therefore, when combined, the term "subsample" essentially means a smaller or secondary sample taken from a larger population or main sample.
