  38. Random Sampling
    Technique for choosing participants that ensures that every member of a population has an equal chance of being included in the sample

  43. The Neuron
  44. Three types of Neurons
    Sensory, Motor, Inter
  45. Sensory Neurons
    receive information from the external world and convey this information to the brain via the spinal cord
  46. Motor Neurons
    carry signals from the spinal cord to the muscles to produce movement
  47. Interneurons
