A questionnaire was given to students. The first question asked was "How stressed have you been in the last week on a scale of 0 to 10 with 0 being not stressed at all and 10 being as stressed as possible? The responses are shown to the right.
a. Which stress rating describes the greatest number of students?
out of 10
\begin{tabular}{|c|c|}
\hline Stress Rating & Frequency \\
\hline 0 & 5 \\
\hline 1 & 4 \\
\hline 2 & 1 \\
\hline 3 & 13 \\
\hline 4 & 17 \\
\hline 5 & 17 \\
\hline 6 & 10 \\
\hline 7 & 31 \\
\hline 8 & 28 \\
\hline 9 & 20 \\
\hline 10 & 13 \\
\hline
\end{tabular}
Answer
So, the stress rating that describes the greatest number of students is \( \boxed{7} \).
Step 1 ：A questionnaire was given to students. The first question asked was 'How stressed have you been in the last week on a scale of 0 to 10 with 0 being not stressed at all and 10 being as stressed as possible? The responses are shown in the table below.
Step 2 ：From the table, we can see the frequency of each stress rating.
Step 3 ：We need to find the stress rating that describes the greatest number of students.
Step 4 ：We can see from the table that the stress rating with the highest frequency is 7.
Step 5 ：So, the stress rating that describes the greatest number of students is \( \boxed{7} \).
