Suppose You Were Interested in Conducting a Study Examining How

question 129

Short Answer

Suppose you were interested in conducting a study examining how ratings of similarity between oneself and another person were related to how attracted one is to the other person.You conduct this study by giving participants a description of a person named "Sarah." Participants are asked to read the description and then rate on a scale from 1 to 10 how similar Sarah is to themselves.You also ask each participant to rate on a scale from 1 to 20 how likeable they think Sarah is.
X = rating of similarity of target to oneself
Y = rating of likability of the target ("Sarah")
62 people participate in your study,and you obtain the following data:
= 6.00 SCP = 66
= 10.00 SS_X = 40
SS_Y = 136
Calculate the Pearson correlation coefficient for the above data.

Exponential Growth

A growth pattern in which the number of entities increases at a rate proportional to the current number, resulting in a rapid increase over time.

Human Population

The total number of humans currently living on Earth, often examined in terms of growth rates, distribution, and density.

Exponential Rates

Growth rates that increase rapidly over time in a proportional manner to the current value, often seen in populations or inflation.
