Explanation on what is the logic behind using the sum of the products of deviation scores as the numerator of the formula for the correlation coefficient? Is this logic sound? Why or why not?© BrainMass Inc. brainmass.com October 25, 2018, 12:35 am ad1c9bdddf
A correlation is a number between -1 and +1 that measures the degree of association between two variables (call them X and Y). A positive value for the correlation implies a positive association (large values of X tend to be associated with large values of Y and small values of X tend to be associated with small values of Y). A negative value for the correlation implies a negative or inverse association (large values of X tend to be associated with small values of Y and vice versa).Pearson's correlation reflects the degree of linear relationship between two variables.
The formula for the Pearson correlation
Suppose we have two variables X and Y, with means XBAR and YBAR respectively and standard ...
The solution provides an explanation of logic behind the sum of products. Psychological statistics is examined.
Nonrational Escalation of Commitment
You and your co-workers had an in-depth discussion about nonrational escalation of commitment. Use your best communication techniques to discuss the following questions: Identify the possible original decisions, the person(s) who could make it, and the person(s) who may escalate the commitment to that decision.
? Describe the circumstances that led to the commitment being escalated
? Where do you think the nonrational escalation of commitment may occur?
? Explain why the escalation is nonrational
? Discuss the impact of this escalation of commitment
I need as much information as possible. Examples would be helpful. Thank you.View Full Posting Details
