A frame identifies all the known units in a population from which a census can be conducted or a random sample can be drawn, providing the structural foundation for the extraction of maximum, reliable information from designed statistical studies with the support of established statistical theories.  <\/span>The significance of the Big Data era is that most data are now digitized, easily stored, and processed in large quantity at relatively low cost.<\/span>  <\/span>Big Data offers unprecedented opportunities for statisticians to rethink and innovate.<\/span>  <\/span>Among the many possibilities offered by Big Data is the creation and maintenance of Dynamic Frames \u2013 frames that are rich in content, capture the most up-to-date data as soon as they become available, and produce results and reports in real time on demand.<\/span><\/div>\n

Traditional Population and Frame<\/span><\/b><\/span><\/div>\n
<\/div>\n
A population is an important concept in the study of statistics.  <\/span>It is commonly understood to be an entire collection of items of interest, be it a nation\u2019s people or businesses, a day’s production of light bulbs, or an ocean\u2019s fish [1,2,3].<\/span><\/div>\n
<\/div>\n
A less well-known term is a frame, or a list of the units that cover the entire population with its identification system.   <\/span>A frame is the working definition of a population under study.  <\/span>It identifies all the known units in a population from which a census can be conducted or a random sample can be drawn, providing the structure for statistical description and analysis about the population [2,4,5].<\/span><\/div>\n
