Biostatistics is a necessary skill for a clinician involved in research 4 (1.6) 17 (6.6) 53 (20.5) 119 (46.1) 65 (25.2)
Biostatistics is a necessary skill for a clinician not involved in research 13 (5.1) 95 (36.8) 104 (40.3) 41 (15.9) 5 (1.9)
Biostatisticians are not necessary for most research 62 (24.1) 104 (40.3) 57 (22.1) 31 (12.0) 4 (1.5)

Perceptions of biostatisticians and evidence based dentistry
Biostatistics is an important part of evidence based dentistry 13 (5.1) 16 (6.2) 32 (12.4) 140 (54.2) 57 (22.1)
Knowledge of biostatistics is necessary when evaluating dental literature 5 (1.9) 20 (7.8) 40 (15.5) 135 (52.3) 58 (22.5)
Evidence based dentistry is important for clinical practice11 (4.3) 14 (5.4) 37 (14.3) 141 (54.8) 55 (21.2)
