From: Flight speed and performance of the wandering albatross with respect to wind

  Value SE df† T p
α f 10.59 0.20 836 53.34 < 0.001
β 0.51 0.02 836 23.22 < 0.001
α m - α f 0.97 0.27 44 3.39 0.002
  1. † Estimated degrees of freedom
  2. α = mean ground speed of males (α m ) and females (α f ), respectively (m/s)
  3. β = slope of line relating ground speed and the component of wind velocity in the direction of flight (ground velocity)
