    • Tables are used to organize and display detailed data in a systematic
    • Tables are the most effective method for comparing the number of students who passed different subjects.

      True
    • Pie charts are suitable for displaying large datasets with complex relationships.
      False
    • What type of chart is ideal for displaying market share proportions?
      Pie chart
    • What type of data presentation is effective for illustrating patterns over time?
      Graphs
    • A frequency polygon is a line graph that connects the midpoints of histogram
    • What is the primary purpose of data presentation?
      Communicate key insights effectively
    • Pie charts are used to highlight key data points and comparisons
    • Line graphs are effective for showing trends over time
    • Graphs are primarily used to display precise numerical data.
      False
    • Tables are useful for comparing precise values across different categories or groups
    • What factors influence the choice of a data presentation method?
      Type of data, audience, specific insights
    • Match the graphical method with its definition:
      Histogram ↔️ Bars represent the frequency of data within specified intervals
      Frequency Polygon ↔️ Line graph connecting the midpoints of histogram bars
    • A frequency polygon is useful for comparing the distributions of multiple variables
    • Box and whisker plots are useful for comparing the distributions of different datasets
    • Charts are less suitable for large datasets or complex relationships.

      True
    • What is a strength of a histogram for displaying frequency distribution?
      Clearly shows data shape
    • Frequency polygons are useful for comparing the distributions of multiple variables.
      True
    • What is the primary use of box and whisker plots?
      Comparing distributions
    • What is the interquartile range (IQR) used for in box and whisker plots?
      Identifying outliers
    • What type of graph is best for showing sales trends over time?
      Line graph
    • Match the presentation method with its key purpose:
      Tables ↔️ Precise numerical display
      Line Graphs ↔️ Show trends over time
      Bar Charts ↔️ Compare categorical data
    • Tables are useful for comparing precise values across different categories
    • Pie charts are the most effective method for showing trends over time.
      False
    • A pie chart is an example of a data presentation method that displays proportions
    • Graphs are best for visualizing trends, while tables are ideal for numerical comparisons.

      True
    • What is a strength of a frequency polygon compared to a histogram?
      Emphasizes overall trend
    • What does the box in a box and whisker plot represent?
      Middle 50% of data
    • Different data presentation methods are chosen based on the data type and intended message
    • Frequency polygons use rectangular bars with gaps to show frequency distribution.
      False
    • Histograms clearly show the shape and spread of the distribution
    • Match the part of a box plot with its meaning:
      Box ↔️ Middle 50% of data
      Whiskers ↔️ Extend to minimum and maximum values
      Outliers ↔️ Data points outside normal range
    • Outliers can distort the overall shape of a histogram or frequency polygon.

      True
    • Match the data presentation method with its strength:
      Tables ↔️ Precise numerical comparisons
      Graphs ↔️ Visual representation of trends
      Charts ↔️ Highlights key data points
    • Tables are effective for visualizing trends over time.
      False
    • What is one reason for summarizing large datasets in data presentation?
      Make data more manageable
    • What is the key consideration when choosing a data presentation method?
      Purpose and nature of data
    • Graphs are effective for visually representing relationships and trends
    • Graphs are suitable for displaying detailed numerical data in a systematic way.
      False
    • Histograms have gaps between rectangular bars, while frequency polygons use a continuous line without gaps.
      True
