Q: What is the best simple method I should use to present, analyze, and interpret the data form below to determine the correlation between two variables?
In the problem statement, you conclude that the distance travelled is likely to be a key factor in determining the time taken for delivery, and your research produces the following results.
- Distance (km): 3.5, 2.4, 4.9, 4.2, 3.0, 1.3, 1.0, 3.0, 1.5, 4.1
- Time (minutes): 16, 13, 19, 18, 12, 11, 8, 14, 9, 16
Required: Present, analyze, and interpret the data using a simple but appropriate method.
The data can be presented as a table of course, but consider also adding a line graph showing this correlation. You might want to calculate the correlation coefficient for statistical proof, even though the line graph will visibly indicate the relationship.
