The coefficient of skewness is a measure of asymmetry in a statistical distribution. It indicates whether the data is skewed to the left, right, or is symmetric. The formula for calculating the coefficient of skewness is [(Mean - Mode) / Standard Deviation]. A positive value indicates right skew, a negative value indicates left skew, and a value of zero indicates a symmetric distribution.

The Pearson's coefficient of skewness is a measure of distribution's symmetry?

It is a descriptive statistical measure used to measure the shape of the curve drawn from the frequency distribution or to measure the direction of variation. It is a measure of how far positively skewed (below the mean) or negatively skewed (above the mean) the majority (that's where the mode comes in) of the data lies. Useful when conducting a study using histograms. (mean - mode) / standard deviation. or [3(Mean-Median)]/Standard deviation

How does a coefficient in front of a formula affect the number of each type of atom in the formula?

A coefficient in front of a formula represents the number of molecules or formula units. It applies to all the atoms within that molecule or formula unit. For example, in the formula 2H₂O, the coefficient '2' means there are two water molecules, resulting in a total of 4 hydrogen atoms and 2 oxygen atoms.


In the formula 2HgO the coefficient is?

The coefficient in front of the compound HgO in the formula 2HgO is 2. This means there are 2 moles of HgO for every 2 moles of the whole compound.


What is a number written to the left of a formula called?

The number written to the left of a chemical formula is called a coefficient. It represents the ratio of moles of each substance in a chemical reaction.
