Questions: Create a Frequency Table Table A shows a class of students exam grades. Use the data from Table A to complete the frequency table. Table A 60 50 30 70 60 70 90 90 70 80 100 70 50 70 100 90 100 80 70 70 100 70 60 80 Score Frequency 30 40 50 60 70 80 100

Solution Steps

First, list all the exam grades from Table A in ascending order to make it easier to count the frequency of each score:

\[ 30, 50, 50, 60, 60, 60, 70, 70, 70, 70, 70, 70, 70, 70, 80, 80, 80, 90, 90, 90, 100, 100, 100, 100 \]

Count how many times each score appears in the list:

• 30: 1
• 40: 0
• 50: 2
• 60: 3
• 70: 8
• 80: 3
• 90: 3
• 100: 4

Using the counts from Step 2, fill in the frequency table:

\[ \begin{tabular}{|r|r|} \hline Score & Frequency \\ \hline 30 & 1 \\ \hline 40 & 0 \\ \hline 50 & 2 \\ \hline 60 & 3 \\ \hline 70 & 8 \\ \hline 80 & 3 \\ \hline 90 & 3 \\ \hline 100 & 4 \\ \hline \end{tabular} \]
