quantity: odd number x even number

[martin2106 (martin martin)]

Hello,
I ask how I should do this program:

I have values entered: odd numbers and even numbers

data = {1, 2, 5, 7, 8, 4, 12, 14, 15, 16, 18, 12, 17, 12, 15}

I need a list of numbers:
Odd numbers: 6
Even numbers: 9

Thank you for the advice

Length[Select[data, EvenQ]]

 9
