Correlations are useful because if you can find out what relationship variables have, you can makepredictions about future behavior. Knowing what the future holds is very important in the social sciences like government and healthcare. Businesses also use these statistics for budgets and business pla...
In statistics, a measure of the strength of the relationship between two variables. It is used to predict the value of one variable given the value of the other. For example, a correlation might relate distance from urban location to gasoline consumption. Expressed on a scale from -1.0 to ...
Spearman’s rho is an excellent choice when you have ordinal data because Pearson’s is not appropriate. Ordinal data have at least three categories and the categories have a natural order. For example, first, second, and third in a race are ordinal data. ...

Of course, finding a perfect correlation is so unlikely in the real world that had we been working with real data, we’d assume we had done something wrong to obtain such a result. But this result from the simplified data in our example should make intuitive sense based on simply looking...
Pearson r correlation:Pearson r correlation is widely used in statistics to measure the degree of the relationship between linear related variables. For example, in the stock market, if we want to measure how two commodities are related to each other, Pearsonrcorrelation is used to measure the ...
In the world of statistics, a perfect positive correlation can be represented by the correlation coefficient value +1.0. A value of 0 indicates that there is no correlation, and a -1.0 shows that there is a negative correlation. Also known as a perfect inverse. ...
Let us understand the correlation formula statisticswith the help of a few examples as discussed below. These examples shall give us a practical overview of the concept and its related factors. It is effortless to calculate thecorrelation in Excel. The syntax of the function used is as follows...
A negative correlation is sometimes described as an inverse correlation. In statistics, a positive correlation describes the relationship between two variables that change together, while aninverse correlationdescribes the relationship between two variables that change in opposing directions. Examples of posit...
In statistics, a perfectly negativecorrelationis represented by the value -1.0, while 0 indicates no correlation, and +1.0 indicates a perfectlypositive correlation. The supply curve is almost always upward-sloping and represented with a positive correlation, reflecting how producers are willing to bri...
