A strong negative correlation occurs when two variables move in opposite directions, with a correlation coefficient close to -1.
Example:
- Hours of Sleep and Fatigue: The more hours of sleep someone gets, the less fatigued they feel. This is a strong negative correlation because as one variable (hours of sleep) increases, the other variable (fatigue) decreases.
Other Examples:
- Exercise and Body Mass Index (BMI): As the amount of exercise increases, the BMI tends to decrease.
- Temperature and Ice Cream Sales: As the temperature rises, the sales of ice cream decrease.
- Number of Vaccinations and Disease Prevalence: As the number of vaccinations increases, the prevalence of certain diseases decreases.
These are just a few examples of strong negative correlations. In each case, the two variables move in opposite directions, indicating a strong inverse relationship.
