WGU Data Driven Decision Making –
C207
Activities (RBM stage) – Answer second step involves the process that converts inputs
to outputs (actions necessary to produces results – training, evaluating, developing)
Alternative hypothesis – Answer The argument that either a sample is not equal to,
greater than, or less than the hypothesized null sample
Analysis of Variance (ANOVA) – 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 – Answer The discovery, analysis, and communication of meaningful patterns
in data.
Autocorrelation – Answer A relationship between two variables that is inherently nonlinear
Balanced Scorecard – 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 – Answer A graph that measures the distribution of data over discrete groups
or categories.
Benchmarks – Answer Standards or points of reference for an industry or sector that can
be used for comparison and evaluation.
Big Data – 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 – Answer A study performed where the participants are not told if they are in
the treatment group or control group
body mass index (BMI) – Answer A measure, based on a person’s weight and height,
that is used to classify people as underweight or overweight.
Business process – Answer A sequence of logically related and time based work
activities to provide a specific output for a customer.
Central Limit Theorem – 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<\/p>\n\n\n\n

Cluster Analysis – Answer The process of arranging terms or values based on different
variables into “natural” groups
Cointegration – Answer Occurs when two time series are moving with a common pattern
due to a connection between the two time series
Combination – Answer The number of different unordered possibilities for a certain
situation.
Complement – Answer The occurrence of an event not happening, the opposite
Confidence interval – Answer An interval estimate used to indicate reliability
Continuous Data – Answer Data that can lay along any point in a range of data
Control chart – 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 – 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 – Answer compare an individual to certain defined standards
Critical Success Factors – Answer The important things an entity must do to be
successful, such as quality measures, customer service, or efficiency.
Cumulative Average-Time Learning Model – Answer A 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 – Answer The probability that a random variable will be found at
a value less than or equal to a given number
Customer satisfaction – Answer A measure of the extent to which customers are
satisfied with the products and related services they received from a supplier.
Cycle time – Answer The 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.
Cyclicality – Answer Repetition of up (peaks) or down movements (troughs) that follow
or counteract a business cycle that can last several years
