WGU Data Driven Decision Making - C207 2022-20231. Activities (RBM stage): second step involves the process that
converts inputs to outputs (actions necessary to produces results -
training, evaluating, developing)
2. Alternative hypothesis: The argument that either a sample is not
equal to, greater than, or less than the hypothesized null sample
3. Analysis of Variance (ANOVA): 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
4. Analytics: The discovery, analysis, and communication of meaningful
patterns in data.
5. Autocorrelation: A relationship between two variables that is
inherently non-lin- ear
6. Balanced Scorecard: An approach using multiple measures to
evaluate per- formance, including financial measures, and the non-
financial measures of cus- tomers, internal business processes, and
learning and growth.
7. Bar chart: A graph that measures the distribution of data over
discrete groups or categories.
8. Benchmarks: Standards or points of reference for an industry or
,sector that can be used for comparison and evaluation.
9. Big Data: very large amounts of data; an all-encompassing term for
any collec- tion of data sets so large and complex that it becomes
difficult to process them using traditional data processing applications

and the more the results will look like a normal distribution
14.Cluster Analysis: The process of arranging terms or values based on
different variables into "natural" groups
15.Cointegration: Occurs when two time series are moving with a
common pattern due to a connection between the two time series
, 16.Combination: The number of different unordered possibilities for
a certain situation.
17.Complement: The occurrence of an event not happening, the
opposite
18.Confidence interval: An interval estimate used to indicate reliability
19.Continuous Data: Data that can lay along any point in a range of
data
20.Control chart: A graphic display of process data over time and
against estab- lished control limits, and that has a centerline that
assists in detecting a trend of plotted values toward either control
limit.
21.Control limits: 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
22.Criterion-reference test: compare an individual to certain defined
standards
23.Critical Success Factors: The important things an entity must
do to be successful, such as quality measures, customer service,
or efficiency.
24.Cumulative Average-Time Learning Model: 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
