Data Visualization

Find a dataset from Internet or from a person$/$business of your connections. And finish the following

tasks:

$(1)$ Briefly describe the context of the data and dataset variables.

a$.$ Is it a simple or joined table $($review $2\mathrm{.}1$ if needed$)?$ Name the entity $($or entities$).$

b$.$ Considering the LOD of your dataset, is there any variable structure?

i$.$ Example of variable structure: department $->$ team $->$ employee

ii$.$ Example $2$: product category $->$ sub category $->$ product

$(2)$ Discuss the dataset within your team and ask $3$ business questions.

Notes:

What is business question: In contrast to data questions, business questions address managerial

insights. For example, "what is the expected cost to hire a data scientist in year $2024?"$ is a business

question because it relates to business decision making such as HR hiring tasks. The question "what is the

average of the salary variable?" is a typical data question because it only relates to a simple calculation.

For each business question:

a$.$ Clearly describe the question, explain why it is important, and to whom. And how

answering this question help decision making.

b$.$ Make tables$/$graphs that toward answering the question.

c$.$ Explain whether your question is answered by the table$/$graph$.$

Requirements :

Send your dataset and $3$ questions to your teacher and get approval before proceed.

Team members must discuss and agree on the dataset and questions before splitting the tasks.

Submission:

The original dataset. $($put it to OneDrive or Google Cloud and submit the link$)$

An integrated report of tasks $(1)$ and $(2).$ Discussions and screenshots of visualizations are

expected. $($Clearly mark who did what part, else put a note of "every team member equally

contributed to this work"$)$
