I have calculated the mean score for several variables. Because there is a big difference in the number of respondents for each variable it might be misleading to compare the means directly. I am wondering if there is some way to adjust the means to account for the diffeent size of respondents and therefore make direct comparisons more valid. So that is to say to have an adjusted mean that would be the mean had the variables all had the same number of people responding. So in the table below you can see that for var1 there were 141 people but for var6 there were only 3 people. Can I adjsut the means to account for the different sample sizes?

Variable N Mean

Var1 141 10.86

Var2 76 0.18

Var4 41 0.34

Var6 3 2.00

Var10 25 0.12
