Step 1: Observe the dotplot provided. Each dot represents the number of students who read a specific number of books in a month. The x-axis shows the number of books read, and the y-axis (represented by the number of dots) shows the frequency of students for each number of books.
Step 2: Count the number of dots above each number on the x-axis to determine the frequency of students for each number of books read. For example, above '0', there are 2 dots, meaning 2 students read 0 books.
Step 3: Identify the number of books read with the highest frequency (most dots). This is the mode of the dataset. Look for the number on the x-axis with the tallest column of dots.
Step 4: Identify the number of books read with the lowest frequency (fewest dots). This is the least frequent value. Look for the number(s) on the x-axis with the shortest column of dots.
Step 5: Record the most frequent and least frequent numbers of books read based on your observations from the dotplot. Ensure to double-check your counts for accuracy.
