,How is data science different from data analytics? Data science focuses on developing new algorithms and models, while data
analytics focuses on using existing models to analyze data.
- Data science focuses more on tracking experimental
data, and data analytics is based on statistical methods
and hypotheses.
- Data science focuses on developing new algorithms
and models, while data analytics focuses on using
existing models to analyze data.
- Data science focuses more on data visualization, while
data analytics focuses on data cleaning and
preprocessing.
- Data science involves creating new algorithms, while
data analytics uses existing statistical methods.
Which comparison describes the difference between Data analytics is the process of analyzing data to extract insights, while data
data analytics and data science? science involves building and testing models to make predictions.
- Data analytics focuses on descriptive analysis, while
data science focuses on prescriptive analysis.
- Data analytics is the process of analyzing data to extract
insights, while data science involves building and testing
models to make predictions.
- Data analytics focuses on statistics, and data science
mainly focuses on qualitative reasoning.
- Data science involves analyzing data from structured
sources, while data analytics involves analyzing data from
unstructured sources.
Which type of data analytics project aims to determine Diagnostic
why something happened in the past?
- Diagnostic
- Descriptive
- Predictive
- Prescriptive
,What are the different types of data analytics projects? Descriptive, diagnostic, predictive, and prescriptive analytics
- Data warehousing, data mining, data visualization, and
business intelligence

What is the difference between exploratory and Exploratory projects involve testing hypotheses and finding patterns in data, while
confirmatory data analytics projects? confirmatory projects involve verifying existing hypotheses.
NOT CORRECT
- Exploratory projects involve testing hypotheses and
finding patterns in data, while confirmatory projects
involve verifying existing hypotheses.
- Exploratory projects involve analyzing data that is
already structured, while confirmatory projects involve
analyzing unstructured data.
- Exploratory projects involve analyzing large datasets,
while confirmatory projects involve analyzing smaller
datasets.
- Exploratory projects involve analyzing data from a
single source, while confirmatory projects involve
integrating data from multiple sources.
