The average grade is 3.78

• The ratio of the sum of the values in a particular set to all the values in the set is the mean value, which is the definition of the average.
• The average formula has numerous practical uses. If one is asked to determine the average male height in India or the average age of the men and women in a group, one needs to add up all the data and divide it by the total number of data points.

Here, according to the given information, we are given that,

The grades received by the 9 students are,

5, 5, 3, 2, 2. 5, 4. 5, 3.

Now, the number of students is equal to 9.

Then, we know that, the average of the marks will be the sum of all the marks divided by the total number of marks.

The sum of the marks = $5+ 5+ 3+2+ 2+ 5+ 4+ 5+ 3 = 34.$

Now, the average of the marks = $\frac{34}{9} = 3.78$

Hence, the average grade is 3.78.
