Logging in western North America impacts populations of western trillium, a long-lived perennial that inhabits confier forests. Jules and Rathcke (1999) measured attributes of eight local populations of western trillium, confined to forest patches of varying size created by logging in southwstern Oregon. Local population Distance to clear-cut edge (m) Recruitment
1 67 0.0053
2 65 0.0021
3 61 0.0069
4 30 0.0006
5 84 0.0124
6 97 0.0045
7 16 0.0028

Using these data, determine which of the following approaches would enable you to do a reasonable job of meeting the assumptions of Pearson's correlation coefficient?
a. Analyzing the data with both variables ('edge distance' and 'recruitment') on the untransformed, raw scale
b. Analyzing the data with 'edge distance' and 'recruitment' both log-transformed
c. Analyzing the data with only 'edge distance' log-transformed
d. Analyzing the data with only 'recruitment' log-transformed
