What is a correlation coefficient and state and explain the meaning of negative values in the correlation coefficient in forecasting ?
Prof. Watson wants to predict children’s aggressive scores based on the participants’ gender and their self-esteem scores. Based on literature and theory, he has reason to believe that gender would be a greater predictor than self-esteem scores. What type of analysis should Prof. Watson do? Why?
An experiment was conducted into various phobias, by the department of Psychology at Lowlands University. One hundred subjects were shown pictures of things that typically induce fear (spiders, violence, extreme heights, bloody wounds etc). They were then asked how frightened they were.
State whether or not the data is suitable for analysis using correlation and regression, and explain fully why you have reached that conclusion.
