from scipy.stats import spearmanr
x = [10, 20, 30, 40, 50]
y = [5, 15, 25, 35, 45]
result = spearmanr(x, y)
print(round(result.correlation, 2))

A0.0

B1.0

C-1.0

D0.5

Step-by-Step Solution

Solution:

Step 1: Understand input data relationship
Both x and y increase together perfectly in order, so their ranks are perfectly correlated.
Step 2: Calculate Spearman correlation
Since ranks match exactly, Spearman correlation is 1.0, indicating perfect positive monotonic relationship.
Final Answer:
1.0 -> Option B
Quick Check:
Perfectly increasing sequences have Spearman correlation = 1.0 [OK]

Quick Trick: Perfectly matching ranks give correlation 1.0 [OK]
