General

• Freeze drying
  A 3² factorial experiment on the effect of freeze-drying on biological material
• Nerve impulse times
  The data are well modelled by an exponential distribution

Human biology

• Vasco-constriction reflex after deep breaths
  Binary data with two associated predictors
• Neural tube defects
  The number of neural tube defects per 10 000 births for England and Wales for every two years between 1977 and 1985 inclusive.
• Tonsils and pyogenes

• Two assay experiments for a hormone
• Height and resting pulse
  The heights and resting pulses for a sample of hospital patients.
• Fingers ridges on identical twins
  The number of fingers ridges on identical twins. The within-sibling variation is small, while the between sibling variation is much larger.
• Statures of brother and sister
  The heights of 11 pairs of brothers and sisters.
• Body dimensions
