WGU C207 DATA DRIVEN UPDATED REVIEW EXAM
PAPER QUESTIONS AND ANSWERS SURE A+
✔✔Confidence interval - ✔✔An interval estimate used to indicate reliability
✔✔Continuous Data - ✔✔Data that can lay along any point in a range of data
✔✔Control chart - ✔✔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 - ✔✔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 - ✔✔compare an individual to certain defined standards
✔✔Critical Success Factors - ✔✔The important things an entity must do to be
successful, such as quality measures, customer service, or efficiency.
✔✔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 doubled
, ✔✔Cumulative distributions - ✔✔The probability that a random variable will be found at
a value less than or equal to a given number
✔✔Customer satisfaction - ✔✔A measure of the extent to which customers are satisfied
with the products and related services they received from a supplier.
✔✔Cycle time - ✔✔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 - ✔✔Repetition of up (peaks) or down movements (troughs) that follow or
counteract a business cycle that can last several years
✔✔Data Management - ✔✔The management, including cleaning and storage, of
collected data.
✔✔Data Mining - ✔✔the process of discovering patterns in large data sets; performed
on big data to decipher patterns from these large databases
✔✔Data Set - ✔✔A collection of related data records on a storage device.
✔✔Davenport Kim Three Stage Model - ✔✔A decision making model developed by
Thomas Davenport and Jinho Kim that consists of three stages: framing the problem,
solving the problem, and communicating results
✔✔Dependent Variable - ✔✔The variable whose value depends on one or more
variables in the equation; typically the cost or activity to be predicted
✔✔Detractor - ✔✔A category of customer used in the calculation of the Net Promoter
Score that indicates an unhappy customer.
✔✔Discrete Data - ✔✔Data that can only take on whole values and has clear
boundaries
✔✔Double Blind Study - ✔✔A study performed where neither the treatment allocator
nor the participant knows which group the participant is in
✔✔Economic Value Added (EVA) - ✔✔Net income (after taxes) earned in excess of the
amount of net income required to earn the company's cost of capital.
✔✔Epidemiology - ✔✔study of the incidence, distribution and possible control of
diseases and other factors relating to health
✔✔Event - ✔✔An outcome that occurs
