What are the sources of data for statistical analysis?
There are two sources of data in Statistics. Statistical sources refer to data that are collected for some official purposes and include censuses and officially conducted surveys. Non-statistical sources refer to the data that are collected for other administrative purposes or for the private sector.
Is a process of collecting and integrating data from multiple sources?
Data integration is the process of combining and consolidating data from multiple sources to provide a single holistic view. The data integration process is often the beginning of many routine data processes, from transformation, mapping, and data analysis.
Why is having many sources important?
Using a variety of sources can diminish the effects of bias—the preference of one view over another. If blatant bias is present in a source, compensate for it with viewpoints from other sources. Using multiple perspectives in this way will help you create a well-rounded source other researchers can use.
