____________________ are programming languages that are very frequently
used for data manipulation and modeling. Answer - Python or R
___________ are general-purpose languages that are used for the back end,
the foundational elementsterm-26 of data science, and they provide maximum
speed. Answer - C, and C++, and Java
____________________ is a language for working with relational databases to
do queries and data manipulation. Answer - SQL
What does SQL stand for? Answer - structured query language
This is where you actually create the statistical model and you do the linear
regression. You do the decision tree. You do the deep learning neural network.
Answer - Modeling
These are the developers, and the system architects, the people who focus on
the hardware and the software that make data science possible Answer - Data
engineers
This is the phase of collecting data. Answer - Data acquisition
Which phase? - Working with stakeholders to help them ask better questions
so that both they and you understand the outcome. Answer - Discovery
,What are the 4 parts of data analytics cycle? Answer - Planning, Wrangling,
Modeling and Applying
This phase is also known as the discovery phase. During this phase, an analyst
defines the major questions of interest that need to be answered, understand
the needs of the stakeholders, and assess the resource constraints in the
project. Answer - Business understanding
____________________ is the person who champions the vision of the project
and has the authority to allocate resources. Answer - The project sponsor
__________________ is responsible for making sure things get done on time
and within budget and removes roadblocks. Answer - Project manager
___________ is when new requirements are added to the project that
increases the time/resources needed to complete it. Answer - Scope creep
What are the 3 types of analysis? Answer - Descriptive, Predictive, Prescriptive
___________________________ describes the data that is present. Mean,
Median, Mode, counting things. How many of each size and color of shirt were
sold in the last month? Do we sell more shirts in the summer vs winter?
Answer - Descriptive analysis
____________________ makes predictions about future state of business.
Forecasting volumes for example. Based on last summer and winter, what will
we sell next year? Answer - Predictive analytics
, _______________________ analysis with an end goal of making a
recommendation. What colors and sizes of shirts should we sell to maximize
profits? Answer - Prescriptive analytics
______________________ is just looking at any variable over time Answer -
Time series analysis
____________________ is a programing language that is specific to statistics. It
also has capabilities to visualize data. Answer - R
_______________ is a multipurpose programing language that has libraries
that extend its capabilities to do statistical analysis. Answer - Python
______________________ are platforms that specialize in visualization. This is
where you can make graphs and charts for presentations and data storytelling
to executive leaders. Answer - Tableau and Power BI
_______________________ are instant messaging platforms that facilitate in a
faster, but less formal, way than email. Answer - Teams, Slack
An European union law regulating their citizens must have informed consent
and ability to request or delete their own data that you collect. Answer - GDPR
When the researching organization consciously ignores data that calls their
results into question or only presents one side of the results that puts them in
a positive light. Answer - Conflict of interest
Sometimes data might not be available and the analyst will use tools such as
web scraping or surveys to acquire it during which phase? Answer - Data
aquisition
