Spearman’s Rank Correlation Coefficient Analysis on Real-World Data
A public health researcher collected data from 20 individuals on their daily exercise time (in minutes) and their corresponding cholesterol levels (in mg/dL). The data (presented as pairs in the format (exercise time, cholesterol)) are as follows: (30, 220), (45, 210), (25, 230), (35, 215), (50, 205), (40, 212), (30, 225), (55, 200), (60, 195), […]
Multiple Tie-Blocks in Spearman’s Rank Correlation
A researcher is investigating the relationship between job satisfaction and workplace environment using ordinal scales. In the collected data from 8 employees, tied ranks occur due to similar satisfaction scores. (a) Identify the tied groups in the dataset for variable X (Job Satisfaction Rank) if the preliminary ranking yields the following order: 1, 2, 2, […]
Part a
Identify the tied groups in variable X using the following preliminary ranking: 1, 2, 2, 4, 5, 5, 5, 8.
Part b
Adjust the ranks by assigning the average rank to each group of ties identified in part (a).
