WGU C207 Objective Assessment (OA) - AnsWer-Exam Coverage
Exam coverage for WGU C207 Objective Assessment (OA) includes foundational
probability and statistics concepts used in business decision-making and data analysis.
It focuses on descriptive statistics, probability distributions, sampling methods,
hypothesis testing, confidence intervals, regression, and correlation. The exam also
evaluates understanding of data interpretation, statistical significance, and application of
statistical methods to business problems.
Emphasis is placed on analyzing data, drawing conclusions from statistical results, and
applying quantitative reasoning to support evidence-based decision-making in business
and organizational contexts.
Weighted Index - AnsWer-assign a weight to allow for significant differences in the
index.
Reasons for including analytics in decision-making - AnsWer-decrease cost of data
storage
increase processing power
Descriptive Analytics - AnsWer-using current and past data for strictly descriptive
purposes.
i.e. car price data shows a 2% increase over the prior year
a manager wants to know why sales spiked during the prior quarter
,Simple indexing - AnsWer-Common analytic measure to improve performance.
Compares current data with data during a base period.
(Price / Price during "Base Period") x 100
i.e. Big Mac was 1.60 in 1968 which is base period. what is index for 2014 if price was
4.80 then?
(4..60) * 100 = 300 (means price is 3x greater than base period)
Used to identify price fluctuations of supplies, materials, products, etc.
Predictive / Inferential Analytics - AnsWer-using current and past data to
predict/estimate future.
i.e. based on the past 10 years of data for car prices, we predict an increase of 1.5% over
the upcoming year.
Prescriptive Analytics - AnsWer-using past data to PREDICT or ESTIMATE future in
order to optimize operations
includes experimental design and optimization to aid in DECISION-MAKING.
MANAGERIAL DECISIONS.
i.e. based on past data, sales prices for electric cars could increase by 5% if we
increased charging stations by 7%
Big data - AnsWer-Data so big that it's difficult to process using traditional methods.
Stored in a Data Warehouse.
Mined to identify patterns and trends
,Primary purpose is to encourage buying behavior.
Enables products to be more tailored to customer base.
Improves decision-making.
Supports development of next generation products/services.
watch for keywords in test options. i.e. company TOTAL sales (just one number) vs all
sales invoices
Structured / Quantitative Data - AnsWer-Data follows pre-defined formats.
i.e. multiple choice answers, addresses, names, stock tickers
Unstructured / Qualitative Data - AnsWer-Data doesn't follow pre-defined formats.
Usually gets structured by a "theme analysis"
i.e. blocks of freeform text, audio, video
Continuous Data - AnsWer-Data that can take any value (within a set range)
i.e. 3.14159, -189,115.2
a thermometer reads 66.5 degrees
Interval Data (data measuring levels) - AnsWer-data is ordered at equal intervals apart
and "0" doesn't mean absence of data, just another data point
a type of continuous data
, i.e. date, time, degrees
Ratio Data (data measuring levels) - AnsWer-0 actually means nothing, not just a data
point
a type of continuous data
i.e. money, height weight
Discrete Data - AnsWer-Data that can only take on whole values and has clear
boundaries
i.e. 4, 7, 8 in a preset range of 1-100
Ordinal data (data measuring levels) - AnsWer-data is ordered based on quality
a type of discrete data
i.e. in blackbelt data, level "3" is higher quality than "1"
gold, silver, and bronze medals
Nominal / Categorical Data (data measuring levels) - AnsWer-data is assigned a
category/label for identification and grouping purposes
a type of discrete data
i.e. males are assigned "0" and females "1"
potential quality errors: categories can be misspelled
