What is the range of correlation coefficient and what does its value tell?
The product-moment correlation coefficient or PMCC should have a value between -1 and 1. A positive value shows a positive linear correlation, and a negative value shows a negative linear correlation. At zero, there is no linear correlation, and the correlation becomes stronger as the value moves further from 0.
What does a graph of Charles law shows the relationship between?
A graph of Charles Law shows the relationship between temperature and volume of gas.
What is the difference between a diagram and a graph?
The difference between a graph and a diagram is as follows: a diagram is a chart which shows a drawing and a graph is a graph with lines or bars indicating something specific in numbers.
Which graph shows the inequality?
A
Which of these correlation numbers shows the strongest relationship?
A correlation coefficient of 1 or -1 would be the highest possible statistical relationship. However, the calculation of correlation coefficients between non independent values or small sets of data may show high coefficients when no relationship exists.
