WGU - C207 - DATA DRIVEN DECISION MAKING
EXAM QUESTIONS AND ANSWERS 100%
CORRECT!!
,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. A statistical method that helps identify the
sources of variability by comparing
their means or averages; it compares the variation within a sample to the variation
between samples to see if any differences are the result of some contributing factor or if
the differences occur by chance alone.
Analytics - ANSWER The discovery, analysis, and communication of meaningful
patterns in data.
Autocorrelation - ANSWER A relationship between two variables that is inherently non-
linear
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.
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. A modified run chart that also provides upper
and/or lower limits that a process should not exceed.
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. See also specification limits.
Criterion-reference test - ANSWER compare an individual to certain defined standards
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.
Data Management - ANSWER The management, including cleaning and storage, of
collected data.
