Individuals from a business training programme are monitored in their first year of business, and their achievement in that first year quantified using a range of tests. The training programme was based on a mentoring system, with young trainees paired in every case with older, more experienced people who were training for a career change. The data for the individuals are below.

Team 1 2 3 4 5 6 7 8

Young Trainee30 44 21 17 25 22 16 28

Mentor23 37 7 18 10 15 13 29

a) Draw a scatterplot of the data, using the mentor's scores to predict the young trainee's scores.

b) Calculate Pearson's correlation for the data, and interpret your figure.

c) Now calculate Spearman's correlation coefficient for the data.

d) Which correlation is most appropiate for the situation, and why?

NOTE:For the data, 30 and 23 under 1, 44 and 37 under 2, etc.

Please help. Thank you!
