Exploring Histograms, Line Graphs, and Bar Charts

What does the length of each rectangle in a histogram represent?

• The class interval

• The frequency of data

• The percentage of data

• The cumulative frequency

In a histogram, how are the rectangles positioned?

• Adjacent to each other

• In random order

• Overlapping each other

• Spaced apart

What is a key characteristic of a grouped frequency histogram?

• No bars are used

• Bars represent individual values

• Only vertical bars are used

• Bars represent ranges of values

What is plotted at each data value in a frequency polygon?

• A circle

• A rectangle

• A line

• A point

How are the points connected in a frequency polygon?

• By curved lines

• By straight lines

• By dotted lines

• Not connected

What additional feature must a frequency polygon have to be considered correct in homework assignments?

• A legend explaining the points

• Color-coded points

• Axis labels

• Segments trailing down to the axis

What type of data change is typically represented using line graphs?

• Numerical changes over time

• Comparative data sets

• Categorical changes

• Static numerical data

What distinguishes a bar graph from a histogram?

• Bars are touching in a bar graph

• Histograms use lines instead of bars

• Bars are not touching in a bar graph

• Bar graphs can only be vertical

What should be included between the bars in a bar graph?

• Overlapping bars

• Random spacing

• Equal spacing

• No space

Which of the following is NOT a visual display of data mentioned in the video?

• Circle graph

• Stem and leaf display

• Pie chart

• Grouped histogram
