TESTED AND APPROVED!!
Ordinal Data -- ANSWER--Data that places data objects into an order according
o some quality with higher order indicating more of that quality
Discrete Data -- ANSWER--Data that can only take on whole values and has
clear boundaries
Interval Data -- ANSWER--Data that is ordered within a range and with each
data point being an equal interval apart
Valid Data -- ANSWER--Data resulting from a test that accurately measures
what it is intended to measure
Big Data -- ANSWER--A catch-phrase that describes a massive volume that is
so large that it's difficult to process using traditional database software
techniques
Page 1 of 48
,Systematic errors -- ANSWER--Errors in measurement that are constant within
a data set, sometimes caused by faulty equipment or bias.
Benchmarks -- ANSWER--Standards or points of reference for an industry or
sector that can be used for comparison and evaluation.
Continuous Data -- ANSWER--Data that can lay along any point in a range of
data
Ratio Data -- ANSWER--Similar to interval data in that the data is ordered
within a range and with each data point being an equal interval apart, also has a
natural zero point which indicates none of the given quality
Data Set -- ANSWER--A collection of related data records on a storage device.
Random Errors -- ANSWER--Error in measurement caused by unpredictable
statistical fluctuations
Information Bias -- ANSWER--A prejudice in the data that results when either
the respondent or the interviewer has an agenda and is not presenting impartial
questions or responding with truly honest responses, respectively
Page 2 of 48
,Nominal Data -- ANSWER--Sometimes called categorical data or qualitative
data, this data type is used to label subjects or data by name
Reliable Data -- ANSWER--Data that is consistent and repeatable Davenport-

Framing the problem
Solving the problem
Communicating the problem
Blind study -- ANSWER--A study performed where the participants are not told
if they are in the treatment group or control group
Double-Blind Study -- ANSWER--A study performed where neither the
treatment allocators nor the participant knows which group the participant is in
Measurement Bias -- ANSWER--A prejudice in the data that results when the
sample is not representative of the population being represented.

, Triple-Blind Study -- ANSWER--A study performed where neither the treatment
allocator nor the participant nor the response gatherer knows which group the
participant is in
Omission Error -- ANSWER--An error because something ( for example, data
or survey responses) is missing.
Analytics -- ANSWER--The discovery, analysis, and communication of
meaningful patterns in data.
Data Management -- ANSWER--The management, including the cleaning and
storage, of collected data
Relational Database -- ANSWER--A database structured to recognize relations
among stored items of information
Statistics -- ANSWER--The science that deals with the interpretation of
numerical facts or data though theories of probability. Also, the numerical facts
or data themselves.
