-0.99872348

-0.89234651

0.69846237

0.72643969

Answer 1

Interpretation rule: strength is determined by the absolute value (|r|); sign gives direction (positive = same direction, negative = opposite). From weakest to strongest:

1. 0.69846237 — moderately strong positive correlation (|r| ≈ 0.70)
2. 0.72643969 — strong positive correlation (|r| ≈ 0.73)
3. -0.89234651 — very strong negative correlation (|r| ≈ 0.89)
4. -0.99872348 — nearly perfect negative correlation (|r| ≈ 0.999)
