+ Applied behavior analysis, Analyzing Behavior, Data collection
  * Frequency is how often a behavior happens. So frequency recording just counts the number of times a behavior happens. Every time a behavior happens it is recorded by the observer. Frequency data is easy to collect so it is used a lot. Behavior analysts use frequency data to determine rate of response. Rate of response is the number of responses for a specific time period.
+ Sound, Sound, Pitch and Intensity:
  * Pitch' is the highness or lowness of sound. Pitch is how humans hear different frequencies. Frequency is determined by the number of vibrations per second. The highest key on a piano, for instance, vibrates 4,000 times per second. Lower keys have lower frequencies. A note an octave higher than another note has twice the frequency of that note
  - The Doppler Effect
  * When a sound source is moving towards someone, the frequency seems to increase. The same thing happens when someone moves toward the sound source. Frequency seems to decrease when someone moves away from a sound source. It also seems to decrease when the sound source moves away from someone. This is the Doppler effect
