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 \( \boxed{7} \).
