COMPLETE QUESTIONS AND VERIFIED ANSWERS
(GRADED A+)
Interval Data - (correct answer) Data that is ordered within a range and with each
data point being an equal interval apart
Statistics - (correct answer) The science that deals with the interpretation of
numerical facts or data through theories of probability. Also, the numerical facts or data
themselves.
Continuous Data - (correct answer) Data that can lay along any point in a range of
data
Ordinal Data - (correct answer) Data that places data objects into an order
according to some quality with higher order indicating more of that quality
Big Data - (correct answer) A catch-phrase that describes a massive volume of data
that is so large that it's difficult to process using traditional database and software
techniques.
Information Bias - (correct 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
Davenport-Kim Three-Stage Model - (correct answer) A decision-making model
developed by Thomas Davenport and Jinho Kim that consists of three stages: framing
the problem, solving the problem, and communicating results
Double-Blind Study - (correct answer) A study performed where neither the
treatment allocator nor the participant knows which group the participant is in
Analytics - (correct answer) The discovery, analysis, and communication of
meaningful patterns in data.
Relational Database - (correct answer) A database structured to recognize relations
among stored items of information.
Benchmarks - (correct answer) Standards or points of reference for an industry or
sector that can be used for comparison and evaluation.
Data Set - (correct answer) A collection of related data records on a storage device.
Valid Data - (correct answer) Data resulting from a test that accurately measures
what it is intended to measure
, Triple-Blind Study - (correct answer) A study performed where neither the treatment
allocator nor the participant nor the response gatherer knows which group the
participant is in
Measurement Bias - (correct answer) A prejudice in the data that results when the
sample is not representative of the population being tested
Systematic Errors - (correct answer) Errors in measurement that are constant within
a data set, sometimes caused by faulty equipment or bias
Nominal Data - (correct answer) Sometimes called categorical data or qualitative
data, this data type is used to label subjects or data by name
Ratio Data - (correct answer) Similar to interval data in that the data that 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.
Random Errors - (correct answer) Errors in measurement caused by unpredictable
statistical fluctuations
Blind Study - (correct answer) A study performed where the participants are not told
if they are in the treatment group or control group
Omission Error - (correct answer) An error because something (for example, data or
survey response) is missing.
Reliable Data - (correct answer) Data that is consistent and repeatable
Discrete Data - (correct answer) Data that can only take on whole values and has
clear boundaries
Sampling without replacement - (correct answer) When a piece of the population
cannot be selected more than once
test statistic - (correct answer) One value used to test the hypothesis, it is a
numerical summary of the data set.
Non-parametric test - (correct answer) A test that does not assume there to be a
structure (maybe a normal distribution) to the population.
Run chart - (correct answer) A line chart that shows performance measurements
over time; helps to uncover trends or aberrations in processes.
Mutually exclusive events - (correct answer) When two or more events are not able
to occur at the same time
