is the discovery, analysis and communication of meaningful patterns in data - Answer-
Analytics
is a prejudice in data that results when either the respondent or the interviewer have
and agenda that affects responses - Answer-Information Bias
places data into categories that are ordered by a predetermined criteria - Answer-

represents errors in data caused by unpredictable statistical fluctuations - Answer-
Random Error
places data into "either or" categories or identifies by name or characteristic - Answer-
Nominal Data
includes cleaning and storage of collected data - Answer-Data management
is a massive amount of data that is difficult to process using traditional database and
software techniques - Answer-Big Data
is numerical data that has a natural zero allowing this data to be added, subtracted,
multiplied and divided - Answer-Ratio Data
is a prejudice in data that results when the sample is not representative of the
population be tested - Answer-Measurement Bias
