How do you compare the means of two samples of different sizes?
One sample has 100 values, 2nd sample has 200. Mean is expressed in percent for each. What is the formula for smoothing this so that the mean for each is comparable? For example, class A's mean final test score is 85%. There are 100 people in that class. Class 2's mean final test score is 70%. There are 200 people in that class.

Means can be compared as usual irrespective of the sample sizes.
I think there is no need for any formula for smoothing as the figures are stated in terms of percentages. When the absolute values are different then only percentages are calculated.
