Graphs and charts

• Why is it important to use the correct type of graph for data presentation?


  To accurately convey the information and insights from the data.
• What is a line graph primarily used for?


  Showing how something changes over time.
• What should be labeled clearly on a line graph?


  Both axes.
• When can you use a line graph?


  When the variable plotted along the axis is continuous.
• Which variables are suitable for a line graph?


  Time, temperature, or distance.
• What does a bar graph typically show?


  The actual quantity of the items in the graph.
• How is the value represented in a bar graph?


  The height or length of each bar represents the value, size, or amount.
• What should be done to make a bar graph easier to read?


  Each bar should have a space between them.
• What does a pie chart compare?


  Parts of a whole.
• What does each segment of a pie chart represent?


  A particular category within the whole data set.
• What is a key tip for using pie charts effectively?


  Do not use too many segments; more than six can be crowded.
• How can you make a segment of a pie chart stand out?


  You can detach one of the segments.
• What is a common issue with using too many segments in a pie chart?


  It becomes too crowded and difficult to see smaller segments.
• What are the main types of graphs and their uses?

  • Line Graph: Shows changes over time (trends).
  • Bar Graph: Displays actual quantities of items.
  • Pie Chart: Compares parts of a whole (percentage distribution).
• What are the best practices for labeling graphs?

  • Label both axes clearly.
  • Ensure it is obvious what is being explained.
  • Use spaces between bars in bar graphs.
