A researcher observed the amount of $ given to a panhandler and rated the happiness of the person being asked on a scale from 1-10. For C & D, happiness is the predictor and $ given is the criterion.


Here are the results:

Happiness Rating = 4 for $0 Given

Happiness Rating = 6 for $1 Given

Happiness Rating = 8 for $3 Given

Happiness Rating = 2 for $0 Given


For Happiness, M = 5, SD = 2.24

For $ Given, M = 1, SD = 1.22


A. What is the correlation coeffecient?

B. Explain your result for part A to someone who's not familiar with correlation coefficient. Make sure you explain the strength & direction of the correlation.

C. What is the predicted Z score on $ given for someone whose happiness is Z = 2?

D. What is the predicted raw score on $ given for someone whose happiness is Z = 2?

Below is data that a researcher collected on the observed decay of a chemical in water as a function of time. The Researcher used an analytically technique to quantify the chemical that reports relative “peak area” or “response” values. As a result, the researcher analyzed a series of known “standards” of chemical “A” to construct a standard curve, from which the concentrations of “A” in the experimental samples could be calculated. It is known that the chemical decays by a...

How can we maximize both experienced happiness and remembered happiness? Kahneman’s peak-end theory of remembered happiness is a good starting point. According to this theory, what we remember most about hedonic experiences are their high points and how they end. The duration of the experience is also a predictor of consumer’s remembered happiness. Select one: True False
