seo – Increase in average CTR but decrease in average position in Google Search results

In the last few months, we have had created new content for some given pages of a hotel microsite.
Upon comparing the performance of those pages (last three months to the previous period), it shows a decrease in average position in Google Search results while the average CTR has improved. Can anyone explain the reason behind such performance? As I know higher the average CTR of a page, the better its average position in the search results. Attached are the performance screenshot of different pages.
