Exploring Segmented Bar Graphs

What total number of people survived the Titanic disaster?

• 1490

• None of the above

• 711

• 2201

Why is it important to use percentages in segmented bar graphs?

• To use less data

• To compare unlike groups effectively

• To make the graph colorful

• To simplify the graph

What does a height of 100 in the segmented bar graph represent?

• 100 people

• 100 casualties

• 100 survivors

• 100% of the people in each category

What percentage of the crew data is represented at the base of the bar?

• 29.8%

• 25%

• 34.8%

• 54.8%

What does the boundary line at 54.8% indicate in the graph?

• None of the above

• Total percentage of survivors

• Sum of two category percentages

• End of the crew data

What does similar size segments in the graph suggest about the variables?

• They are irrelevant

• They are independent

• They are inconsistently represented

• They are dependent

Which class had a higher survival rate according to the graph?

• Crew

• Third class

• First class

• Second class

What does the independence of variables in a segmented bar graph indicate?

• Complex relationship between variables

• High correlation between variables

• All variables are numerical

• No significant relationship between variables

Why is it crucial to understand segmented bar graphs for categorical data?

• To predict future trends

• To create complex mathematical models

• To produce 3D visualizations

• To analyze relationships between categories

What conclusion can be drawn about the dependency of survival rates on passenger status?

• No conclusion can be drawn

• They are independent

• They are slightly dependent

• They are highly dependent
