WebHigh degree: If the coefficient value lies between ± 0.50 and ± 1, then it is said to be a strong correlation. Moderate degree: If the value lies between ± 0.30 and ± 0.49, then it is said to be a medium correlation. Low degree: When the value lies below + .29, then it is said to be a small correlation. No correlation: When the value is zero. WebThis tells us that there are 525,600 minutes in a year. To find the number of deaths per minute, we simply divide the total number of deaths per year by the number of minutes in a year: 3,400,000 deaths/year ÷ 525,600 minutes/year ≈ 5.8 deaths/minute. So in country A, on average, about 5.8 people die every minute. Here are a few more examples:
