WGU Data Driven Decision Making -
C207 questios and answers 2023
Activities (RBM stage) - answersecond step involves the process that converts inputs to
outputs (actions necessary to produces results - training, evaluating, developing)
Alternative hypothesis - answerThe argument that either a sample is not equal to,
greater than, or less than the hypothesized null sample
Analysis of Variance (ANOVA) - answera 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 - answerThe discovery, analysis, and communication of meaningful patterns in
data.
Autocorrelation - answerA relationship between two variables that is inherently non-
linear
Balanced Scorecard - answerAn 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 - answerA graph that measures the distribution of data over discrete groups or
categories.
Benchmarks - answerStandards or points of reference for an industry or sector that can
be used for comparison and evaluation.
Big Data - answervery 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 - answerA study performed where the participants are not told if they are in
the treatment group or control group
body mass index (BMI) - answerA measure, based on a person's weight and height,
that is used to classify people as underweight or overweight.
Business process - answerA sequence of logically related and time based work
activities to provide a specific output for a customer.
, Central Limit Theorem - answerA 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 - answerThe process of arranging terms or values based on different
variables into "natural" groups
Cointegration - answerOccurs when two time series are moving with a common pattern
due to a connection between the two time series
Combination - answerThe number of different unordered possibilities for a certain
situation.
Complement - answerThe occurrence of an event not happening, the opposite
Confidence interval - answerAn interval estimate used to indicate reliability
Continuous Data - answerData that can lay along any point in a range of data
Control chart - answerA 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 - answerThe 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 - answercompare an individual to certain defined standards
Critical Success Factors - answerThe important things an entity must do to be
successful, such as quality measures, customer service, or efficiency.
Cumulative Average-Time Learning Model - answerA learning curve model in which the
cumulative average time per unit declines by a constant percentage each time the
cumulative quantity of units produced is doubled
Cumulative distributions - answerThe probability that a random variable will be found at
a value less than or equal to a given number
Customer satisfaction - answerA measure of the extent to which customers are satisfied
with the products and related services they received from a supplier.
Cycle time - answerThe total elapsed time to move a unit of work from the beginning to
the end of a physical process, as defined by the producer and the customer.
