Positive correlation.
On a graph it is shown by a line that goes from the bottom left towards the top right. There are fewer conventions about presenting data in a table and it is not possible to say how it might be shown. One possibility is that there is a column of y values and a column of x values. And both increase (decrease) together.
% change is the % of increase or % of decrease. % change = (difference of the two values / the original value) x 100% =[(original value - new value)/original value] x 100% % increase -if the value increased % decrease -if the value decreased
Y would decrease in value as X increases in value.
This has a negative slope (it slopes 'down' as you move from left to right).
one set of data values increases as the other decreases
Decrease your scale values. The higher the scale values, the stronger the correlation
The value of a correlation coefficient reflects the strength and direction of the relationship between two variables. A correlation coefficient ranges from -1 to 1, with 1 indicating a perfect positive relationship, 0 indicating no relationship, and -1 indicating a perfect negative relationship.
The values of the range also tend to increase.
It is a positive relationship.

Positive Correlation
When r is close to +1 the variables have a positive correlation between them; as the x-values increase, the corresponding y-values increase. There is also a strong linear correlation or relationship between the variables, when the value of r is close to +1.

In general the highest will decrease (more) and the lowest will increase (somewhat), but NEVER linearly average pH values, because it is an exponential unit. ( [H+] = 10-pH )
