This Exam contains:
➢ 215 Questions and Answers
➢ 100% Guarantee Pass
➢ Multiple-Choice & Short Answer
➢ Each Question Includes The Correct
Answer
➢ Expert-Verified explanation
,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
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
a type of continuous data
i.e. date, time, degrees
Ratio Data (data measuring levels) - Correct answer ✔✔ - 0 actually means nothing, not just
a data point
a type of continuous data
i.e. money, height weight
Discrete Data - Correct 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) - Correct 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) - Correct 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
Attribute Data - Correct answer ✔✔ - Data that shows whether a result meets a requirement
or not (yes/no, pass/fail).
Davenport-Kim Three-Stage Model - Correct answer ✔✔ - 1. Frame the problem -
recognize problem and review previous findings.
2. Solve the problem - modeling, collection, analysis
3. Communicate results - tailor to audience, use visuals, show results.
Reliability of Data - Correct answer ✔✔ - data that is consistent (but not necessarily accurate)
i.e. a thermometer reads 20, 21, 21, 20, 19, 19, 21, 20, 19
a test given to a student consistently shows similar scores
Validity of Data - Correct answer ✔✔ - data that is accurate
requires sample selection to be adequate size and random.
