skewness=(mean-mode)/standard deviation
The correlation coefficient for two variables is a measure of the degree to which the variables change together. The correlation coefficient ranges between -1 and +1. At +1, the two variables are in perfect agreement in the sense that any increase in one is matched by an increase in the other. An increase of twice as much in the first is accompanied by double the increase in the second. A correlation coefficient of -1 indicates that the two variables are in perfect opposition. The changes in the two variables are similar to when the correlation coefficient is +1, but this time an increase in one variable is accompanied by a decrease in the other. A correlation coefficient near 0 indicates that the two variables do not move in harmony. An increase in one is as likely to be accompanied by an increase in the other variable as a decrease. It is very very important to remember that a correlation coefficient does not indicate causality.

Karl Pearson simplified the topic of skewness and gave us some formulas to help. The first is the Pearson mode or first skewness coefficient. It is defined by the (mean-median)/standard deviation. So in this case the Pearson mode is: (8-6)/2 =1 There is also the Pearson Median. This is also called second skewness coefficient. It is defined as 3(mean-median)/standard deviation which in this case is 6/2 =3 hence the distribution is positive skewed
How old are you? If you are still young and just having your first periods, it probably means your body hasn't gotten into a natural cycle yet.
Natural selection can only work on genetic variation that already exists. So mutation comes first, then natural selection.
Economic stability is measured in two ways. First it can be measured by the coefficient of variation (stability of output growth) or secondly by the 10 year average for inflation.
The characteristic within the population that causes natural selection to occur is that individuals within a given population are not all identical because they vary. The other characteristic that causes natural selection to occur is that some variants are better than the others.
The first condition of Darwin's Theory of Natural Selection by Descent with Modification is that individuals within a population exhibit variation in their traits.
It is customary to provide latitude first and longitude second when plotting locations. Latitude represents how far north or south a location is from the equator, while longitude represents how far east or west of the prime meridian a location is.
Darwin meant that natural selection acts on the variations that are already present in a population. It does not create new variations but rather amplifies the frequency of beneficial traits that are advantageous for survival and reproduction. In this way, natural selection shapes the characteristics of a population over time.
The first description of the process of genetic variation could probably be attributed to Charles Robert Darwin, who is the originator of the Theory of Evolution.

Darwin made bold assumptions about heritable variation, the age of Earth, and relationships among organisms. First, in order for beak size and shape to evolve, there must be enough heritable variation in those traits to provide raw material for natural selection. Second, differences in beak size and shape must produce differences in fitness that cause natural selection to occur.
No. It's not necessary. Example: First, compute for the greatest coefficient.
