1. ## Pearson's and Spearman's help!!

Nine randomly selected subjects of the same sex were questioned on the degree of anxiety they felt about their romantic attachments, eg by responding to items such as "I rarely worry about my partner leaving me" and also on their avoidance score which is a score relating to people's comfort with closeness in relationships, using items such as "I prefer not to show a partner how I feel deep down". The data is below:

Anxiety level x: 2.17 0.89 3.11 3.11 2.28 3.00 0.94 2.89 3.94
Avoidance Score y: 0.89 1.11 2.5 2.72 3.17 2.61 2.39 2.44 1.78

Calculate both Pearson's correlation coefficient and Spearman's correlation coefficient for this data. Draw a scatterplot of the data and use it to decide which of these two correlation coefficients seems more appropriate. Give a reason for your decision.

What is the problem that you are having with this, you have the definition
of the two correlation coefficients. Presumably you know how to construct
a scatter plot.
