Solved Example on Discrete Data
Ques: The table shows the collection of coins by Sandy. Which type of graph is appropriate to display the data in the table?
Choices:A. Bar graph
C. Line graph
D. Stem-and-leaf plot
Correct Answer: A
Step 1: The data given in the table are discrete.
Step 2: Bar graphs are used to represent discrete data.
Step 3: So, a bar graph is appropriate to display the data shown in the table.
