Detailed explanation-1: -A positive correlation is where the two variables react in the same way, increasing or decreasing together. Temperature in Celsius and Fahrenheit have a positive correlation.
Detailed explanation-2: -Complete correlation between two variables is expressed by either + 1 or-1. When one variable increases as the other increases the correlation is positive; when one decreases as the other increases it is negative. Complete absence of correlation is represented by 0.
Detailed explanation-3: -A positive correlation implies a positive relationship between X and Y: as X increases, Y increases. A negative correlation implies a negative relationship between X and Y: as X increases, Y decreases. A correlation of zero implies that there is no linear relationship between X and Y (see below for details).
Detailed explanation-4: -Positive correlation is the relationship between two variables that change together. Inverse correlation is the relationship between two variables that change in opposite directions.
Detailed explanation-5: -A negative correlation is a relationship between two variables such that as the value of one variable increases, the other decreases. Correlation is expressed on a range from +1 to-1, known as the correlation coefficent.
