Question 1: What is the purpose of a bar graph?

• To measure temperature

• To write a novel

• To play music in a bar

• To compare different categories of data by representing them as bars of different lengths.

Question 2: How are bar graphs different from line graphs?

• Bar graphs use lines to represent data, while line graphs use bars to connect data points.

• Bar graphs use circles to represent data, while line graphs use squares to connect data points.

• Bar graphs use dots to represent data, while line graphs use zigzag lines to connect data points.

• Bar graphs use bars to represent data, while line graphs use lines to connect data points.

Question 3: Name one data visualization tool that can be used to create charts and graphs.

• Microsoft Excel

• Adobe Photoshop

• Google Docs

• AutoCAD

Question 4: How can data visualization tools help in understanding complex data?

• By removing all visual elements from the data

• By making the data more complicated

• By converting the data into audio format

• By presenting the information in a visual format

Question 5: What are the key components of a data dashboard?

• Social media, email, and messaging apps

• Data analysis, programming, and coding

• Cooking recipes, travel photos, and weather updates

• Data visualization, charts, graphs, tables, and key performance indicators (KPIs)

Question 6: How can data dashboards be customized to display specific data?

• By not arranging the layout of the dashboard

• By using a single data source and fixed visualization type

• By selecting specific data sources, choosing the type of visualization, and arranging the layout of the dashboard.

• By randomly selecting data sources and visualization types

Question 7: What is the main difference between a table and a chart for data representation?

• Tables are used for words, while charts are used for numbers

• Tables are 3D, while charts are 2D

• Tables are only used in Excel, while charts are used in PowerPoint

• The main difference is the way data is presented: tables use rows and columns, while charts use visual elements.

Question 8: How can you interpret trends and patterns from a line graph?

• By tasting the line

• By counting the number of colors used

• By analyzing the direction, steepness, and recurring patterns of the lines.

• By listening to the line

Question 9: What is the primary purpose of a pie chart?

• To bake a pie

• To measure time

• To compare parts of a whole by representing them as slices of a pie

• To play a game of chess

Question 10: How can data visualization aid in decision-making processes?

• By making decisions randomly

• By ignoring data completely

• By providing a clear and visual representation of data for better understanding and analysis

• By using intuition and gut feeling
