The population mean symbol is μ. Formula The formula to find the population mean is: μ = (Σ * X)/ N where: Σ means “the sum of.” X = all the individual items in the group. N = the number of items in the group.
mean 1 (mēn) v. meant (mĕnt), mean·ing, means v.tr. 1. a. To be used to convey; denote: "'The question is,' said Alice, 'whether you can make words mean so many different things'" (Lewis Carroll). b. To act as a symbol of; signify or represent: In this poem, th...
Population variance, therefore (with a population variance symbol, σ2), tells us how these data points are spread out in a specific population. It is the average distance from each data point in the population to the mean squared. How to calculate population variance? Population variance formul...
First calculate the mean value {eq}\mu {/eq}. Subtract {eq}\mu {/eq} from each data point in the population. Square the deviations calculated in the previous step. Add up the squared values and divide by the population size to calculate the population variance. Population...

Ancient DNA was extracted from either dental cementum or petrous bones, and the 317 genomes were shotgun-sequenced to a depth of coverage ranging between 0.01× and 7.1× (mean, 0.75×, median, 0.26×), with more than 1× coverage for 81 genomes (Supplementary Note 1). We used a compu...
This chapter presents inferences about the mean of a single population. The null hypothesis, denoted by the symbol H 0 , and the alternative hypothesis, denoted by H 1 . It is important to understand that one cannot prove whether H 0 or H 1 is true because one cannot measure the entire...

The population differentiation across all honey bee populations was analysed by pairwise FST values, as shown in Table 2. The mean FST estimate was 0.088 including the AML, while only between the AMC populations, mean FST value was 0.061. The FST values ranged from 0.000 (between the SRB and...
