WGU C207 Data Driven Decision Making Exam 146
Questions with Verified Answers
Activities (RBM stage) - CORRECT ANSWER second step involves the process that
converts inputs to outputs (actions necessary to produces results - training,
evaluating, developing)
Alternative hypothesis - CORRECT ANSWER The argument that either a sample is
not equal to, greater than, or less than the hypothesized null sample
Analysis of Variance (ANOVA) - CORRECT ANSWER a technique used to determine
if there is a sufficient evidence from sample data of three or more populations to
conclude that the means of the population are not all equal
Analytics - CORRECT ANSWER The discovery, analysis, and communication of
meaningful patterns in data.
Autocorrelation - CORRECT ANSWER A relationship between two variables that is
inherently non-linear
Balanced Scorecard - CORRECT ANSWER An approach using multiple measures to
evaluate performance, including financial measures, and the non-financial
measures of customers, internal business processes, and learning and growth.
Bar chart - CORRECT ANSWER A graph that measures the distribution of data over
discrete groups or categories.
,Benchmarks - CORRECT ANSWER Standards or points of reference for an industry
or sector that can be used for comparison and evaluation.
Big Data - CORRECT ANSWER very large amounts of data; an all-encompassing
term for any collection of data sets so large and complex that it becomes difficult
to process them using traditional data processing applications
Blind Study - CORRECT ANSWER A study performed where the participants are not
told if they are in the treatment group or control group
body mass index (BMI) - CORRECT ANSWER A measure, based on a person's
weight and height, that is used to classify people as underweight or overweight.
Business process - CORRECT ANSWER A sequence of logically related and time
based work activities to provide a specific output for a customer.
Central Limit Theorem - CORRECT ANSWER A theorem that states that, the greater
the sample, the closer the mean of the sample is to the entire population and the
more the results will look like a normal distribution
Cluster Analysis - CORRECT ANSWER The process of arranging terms or values
based on different variables into "natural" groups
Cointegration - CORRECT ANSWER Occurs when two time series are moving with a
common pattern due to a connection between the two time series
, Combination - CORRECT ANSWER The number of different unordered possibilities
for a certain situation.
Complement - CORRECT ANSWER The occurrence of an event not happening, the
opposite
Confidence interval - CORRECT ANSWER An interval estimate used to indicate
reliability
Continuous Data - CORRECT ANSWER Data that can lay along any point in a range
of data
Control chart - CORRECT ANSWER A graphic display of process data over time and
against established control limits, and that has a centerline that assists in
detecting a trend of plotted values toward either control limit.
Control limits - CORRECT ANSWER The area composed of three standard
deviations on either side of the centerline, or mean, of a normal distribution of
data plotted on a control chart that reflects the expected variation in the data
Criterion-reference test - CORRECT ANSWER compare an individual to certain
defined standards
Critical Success Factors - CORRECT ANSWER The important things an entity must
do to be successful, such as quality measures, customer service, or efficiency.
