If the form is nonlinear (like if the data is in the shape of a parabola) then there could be a strong association and weak correlation.

Pearson's Product Moment Correlation Coefficient indicates how strong the relationship between variables is. A PMCC of zero or very close would mean a very weak correlation. A PMCC of around 1 means a strong correlation.

It means you have a slight negative correlation between the two variables of interest. As one increases the other decrease and vice versa, albeit in a weak fashion.

Yes there is a weak force between the particles in a solid

The relationship is that all weak acids/bases are weak electrolytes. However, not all weak electrolytes are weak acids/bases.

A correlation near 0 indicates a weak linear association.

No - There is no relationship between weakness and pregnancy. There are innumerable weak women in poor countries who conceive almost every year. However, there is a close association between weakness and the improper growth of the fetus of the unborn child.

A correlation is the relationship between two or more variables. Correlations are described as either weak or strong, and positive or negative. There can be a perfect correlation between variables, or no correlation between variables. It is important to determine the correlation between variables in order to know if and how closely changes in one variable are reflected by changes in another variable. This is done by determining the coefficient of correlation (r), which describes the strength of the relationship between variables and the direction. -1 â‰¤ r â‰¤ +1 if r= +1 or -1, there is a perfect correlation if r= 0 there is no correlation between the variables. a value closer to + or - 1 demonstrates a strong correlation, while a value closer to 0 demonstrates a weak correlation. a + value demonstrates that when one variable increases the other variable increases, while a - value demonstrates that when one variable increases the other variable decreases. However, it is very important to understand that correlation is not the same as relationship. Consider the two variables, x and y such that y = x2 where x lies between -a and +a. There is a clear and well-defined relationship between x and y, but the correlation coefficient r is 0. This is true of any pair of variables whose graph is symmetric about one axis. Conversely, a high correlation coefficient does not mean a strong relationship - at least, not a strong causal relationship. There is pretty strong correlation between my age and [the log of] the number of television sets in the world. That is not because TV makes me grow old nor that my ageing produces TVs. The reason is that both variables are related to the passage of time.

Some rocks are easily broken due to the weak bonds between the molecules in them. For instance, muscovite is easily torn because of the weak bond between the fourth silica in the silicate tetrahedron. There are strong bonds between some molecules and weak bonds between others. The breaks occur along the weak bonds.

The weak bond that forms between water molecules is called a hydrogen bond.

Strong alkali neutralizes acid easily but weak acid can't.

Hydrogen bond a weak chemical attraction between polar molecules, such as two water molecules. Cohesion is an attraction between substances of the same kind.

Salts of weak acids and bases are the ionic compounds formed by the reaction between a weak base and a weak acid. For example, if acetic acid was to react with ammonium, the salt ammonium acetate would form.
