Five recommended readability tests were conducted using an online service to calculate readability. Overall, the analysis indicates that flu material found on the web is not being written at a level that is widely readable.
None of the 100 sites included in the analysis received an acceptable score on all 5 assessments. One-sample independent t tests (α = 0.05, df = 99) indicated that it is highly unlikely that flu Web sites are being written at the desirable level.
