Explain the difference between an independent variable and a dependent variable as used in the experimental method.
(1) The independent variable is the variable that is being manipulated. This variable is what affects the dependent variable.
(2) The dependent variable is the variable that is not manipulated in any way, but is the result of the manipulation of an independent varable.
Dr. Bob found a significant positive correlation of +.90 the number of college courses completed and level of happiness, and therefore concludes the enrolling in college leads to a happier life. Is Dr. Bob correct is his conclusion? Why or why not?
No, one of the stated rules when it comes to experiments the rule is “correlation does not equal causation”.

Although there is not enough data to suggest that more college courses completed CAUSES happiness or vice-versa.

Our sense of smell can route information directly to the cortex, instead of passing through the thalamus first.
List and define the two characteristics of sound waves that correspond to loudness and pitch.
Amplitude and Frequency both contribute to sound waves. Amplitude, reflects how “high” a wave gets.
Frequency measures how many times a wave “loops” (repeadidly goes up and down).
Amplitude determines ther “loudness” while frequency determines the pitch.
