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.
