Document Summary
I. v depend on what you do to dv. Cure for selection bias is random selection and assignment. Experimenter bias researchers prejudicial ideas cause them to find what they expect to find. Can influence the participant or the researcher. (e. g facial expressions) 2 examples of them is placebo positive response to treatment due to expectations not the actual treatment.

Measures of central tendency tend to fall apart. Standard deviation is an index score based on distribution. Tells where in relation to general plot, where the score falls. Number of neurons in average human brain =80 100bn. # of synapses/neuron-1-10k timescale for a bit =<100 msec. Neurons are specialized cells that carry messages throughout the spinal cord. Efferent neurons send info from skin into nervous sytem. Interneurons carry neurons throughout parts of the body.
