- you should use more descriptive variable names

- gets.chomp is already a string
- you can push a new element to an array with <<,
   so that you do not need an index i

you do not need the empty string

names = []
heights = []

puts "calculation of heights"

answer = nil
while answer != 'n'
   print 'Enter name: '
   names << gets.chomp
   print 'Enter height: '
   heights << gets.to_f

   print 'Again? [y/n] '
   answer = gets.chomp
   puts
end
