WGU - C207 DATA DRIVEN DECISION
MAKING EXAM QUESTIONS AND
ANSWERS (CORRECT AND VERIFIED
ANSWERS) LATEST UPDATE
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 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.
, 2
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
Cluster Analysis - (ANSWER)The process of arranging terms or values based on
different variables into "natural" groups
, 3
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
