C207 OA 2026 QUESTIONS AND
ANSWERS | A+ GRADED | WITH
EXPERT SOLUTIONS
Simple indexing - correct 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.
Weighted Index - correct answer-assign a weight to allow for
significant differences in the index.

Reasons for including analytics in decision-making - correct
answer-decrease cost of data storage
increase processing power
Descriptive Analytics - correct 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
Predictive / Inferential Analytics - correct 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 - correct answer-using past data to
PREDICT or ESTIMATE future in order to optimize operations
, Page | 3
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 - correct 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 - correct answer-Data follows pre-
defined formats.
i.e. multiple choice answers, addresses, names, stock tickers
Unstructured / Qualitative Data - correct 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 - correct 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) - correct answer-data is
ordered at equal intervals apart and "0" doesn't mean absence of
data, just another data point
