WebPearson correlation coefficient (PCC) can calculate the linear correlation between different variables [19]. The PCC value changes between − 1 and 1 [20]. The absolute value of PCC ranges from 0 to 1. The higher the absolute PCC value is, the stronger the correlation is [21]. If the sign is negative, the correlation is negative.

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: gallstones are also known as cholelithiasis
