QUESTIONS AND SOLUTIONS VERIFIED
STUDY RESOURCE
●● 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
●● 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.
●● 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-Kim Three Stages Model
Answer: A decision-making model developed by Thomas Davenport and
Jinho Kim that consists of three stages:
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

●● Relational Database
Answer: A database structured to recognize relations among stored items

●● 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
●● 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.
