Chi-Square is for count data, you don't appear to have count data.

That is also NOT 2x2 data.

Do you have actual counts or possibly even better data with one record per observation?

You can get significantly different results comparing percentages when the percentages are the same but the group counts differ significantly.

Then you need to explain your question. You need the N's even if it's just the total and you back calculate the N based on percentages.

If you don't have N's you can calculate the variance and you can't do any tests.

There's a difference between tossing two coins and getting two heads versus tossing a coin 100 times and getting 100 heads.
