Day 5: Introduction to Correlation
Submissions will no longer be placed on the leaderboard. You may still attempt this problem for practice.
Objective
In this challenge, we practice calculating correlation. Check out the Resources tab to learn more!
Task
You are provided the popularity scores for a set of juices (the higher, the better):
[10, 9.8, 8, 7.8, 7.7, 7, 6, 5, 4, 2]
These are the respective prices for the juices:
[200, 44, 32, 24, 22, 17, 15, 12, 8, 4]
Write a program computing (or calculate manually) the Pearson coefficient and the Spearman Rank coefficient of correlation between these values.
Output Format
You must have lines of output:
- The first line must contain the Pearson coefficient, correct to a scale of decimal places.
- The second line must contain the Spearman coefficient, correct to a scale of decimal place.
You can submit solutions in either of the following ways:
- Solve the problem manually and submit your result as Plain Text. In the text box below, enter lines of floating point/decimal numbers.
- Submit an R or Python program, which uses the above parameters (hard-coded), then computes and prints the answer.
Your answer should look similar to the below figures, and must not contain any extra white space or newline characters:
0.758
