skewness in random numbers

I am generating 30 random numbers ranging within 8 32 by

w1=randi([8 32],1,30);

Now I need a skewness in this randomly generated..i.e. the avg difference between the elements needs to be smaller,

like 8 8 9 10 10 11 12 13 13 14......like this way

If I could draw this distribution from a normal distribution then the std deviation that's I need to make smaller...

is there any way to do so?
