The stem-and-leaf plot shows the test scores of a science class. Use the plot to answer the question.
How many students scored 78?
A. 1 student
B. 2 students
C. 3 students
D. 4 students
To determine how many students scored 78 based on the stem-and-leaf plot, follow these steps:
1. Understand the stem-and-leaf plot: A stem-and-leaf plot is a visual representation of numerical data where the tens digit (stem) and the ones digit (leaves) are used to organize the data. The stems represent the tens digit, while the leaves represent the ones digit.
2. Locate the stem for 78: Look for the stem that represents the tens digit of 78. For example, if the stem is "7," it means that the score starts with 70.
3. Count the number of leaves: Once you have identified the stem that corresponds to 78, count the number of leaves attached to that stem. Each leaf represents a student.
4. Determine the answer: The number of leaves attached to the stem for 78 represents the number of students who scored 78.
Based on the information provided in the question, the options are:
A. 1 student
B. 2 students
C. 3 students
D. 4 students
By following the steps above, you can determine the correct answer by referring to the stem-and-leaf plot.
