Felson et al. (1) Compared articles published in Arthritis and Rheumatism in 1982 and 1967-168 with regard to the use of statistical methods and statistical misuse.
Of the articles published in 1982 using statistical methods 66% had methodological errors. In 1967-1968 fewer articles used statistics but of these the percentage with methodological errors was similar. The most common error in 1967-1968 was failure to identify the statistical method used. In 1982 the main problem was multiple testing errors.
The authors recommend using ANOVA instead of repeated testing with Student’s t-test.
