Click the "Recheck Document" button. Click "Yes" in the onscreen prompt. The statistics will reset. Press "OK" to leave the "Word Options" window.
Click the "Review" tab in the ribbon at the top of the window and click the "Spelling & Grammar icon on the left. Recheck the spelling and grammar in the window that opens on the screen. After completing the spelling and grammar recheck, the readability statistics will open in a window.
