PS102 Lecture Notes - Lecture 2: Optic Nerve, Null Hypothesis, Statistical Significance
Document Summary
The positive or negative sign reflects direction not strength. 0 to 1 = positive and -1 to 0 = 0 negative. The closer it is to 1, the higher the correlation (regardless of its sign) Because you can have access to two points of info but may not be able to manipulate the variables. Lots of different tests selected on the basis of the characteristics of the study (compares mean scores) Try to determine if the results are due to chance or not (null hypothesis) Process through which the senses detect visual, auditory, and other sensory stimuli and transmit them to the brain. Process by which information is actively organized and interpreted by the brain. Info goes to the brain through that optic nerve but there is nothing o pick up and no photo reception. Sensory transduction = converting info in environment into neural impulses.
