I'm particularly interested why N appears in the denominator for the formula of population variance, but (n-1) appears in the denominator for the sample variance, where N is the total number of elements in the population and n is the total number of elements in the simple random sample? Basically, the (n-1) seems less intuitive to me. The population mean and standard deviation are two common parameters. In statistics, Greek symbols usually represent population parameters, such as μ (mu) for the mean and σ (sigma) for the standard deviation. A statistic is a characteristic of a sample.

All these types of maps use dots for symbology. Graduated symbols and proportional symbols scale the size of the symbol based on value. But gradual symbol maps puts each value into a class and scales it based on class. Dot distribution maps are different because they just add more dots instead of … Had we used the complete population, we could divide by the actual number of dataset.
