Correlations between observed data are at the heart of all empirical research that strives for establishing lawful regularities. However, there are numerous ways to assess these correlations, and there are numerous ways to make sense of them. This essay presents a bird's eye perspective on ...
How to Interpret Correlation Analysis Correlation coefficients range from 0 to 1, where the higher the coefficient means the stronger correlation. When the value is greater than 0.7, there is considered to be a strong correlation between the two variables. All correlation strength scores and ...
I use the example below in my post abouthow to interpret regression p-values and coefficients. The graph displays a regression model that assesses the relationship between height and weight. For this post, I modified the y-axis scale to illustrate the y-intercept, but the overall results haven...
Additional Ways to Interpret the F-test of Overall Significance If you have a statistically significant overall F-test, you can draw several other conclusions. For the model with no independent variables, the intercept-only model, all of the model’s predictions equal the mean of the dependent ...
Let’s assume a set of data labeled by two variables, X and Y. Thus, theCorrelation Coefficientcan be formulated as: Where, x̄andȳare the sample meansAVERAGEofXvariable andAVERAGEofYvariable. On the other hand,Regressionanalysis is a statistical technique devoted to estimating the connectio...

A problem with covariance as a statistical tool alone is that it is challenging to interpret. This leads us to Pearson’s correlation coefficient next. Pearson’s Correlation Named after Karl Pearson, The Pearson correlation coefficient can be used to summarize the strength of the linear relationshi...
How to interpret the results of correlation coefficient in Excel Interpreting the results of the correlation coefficient in Excel is relatively simple. As mentioned earlier, the correlation coefficient ranges from -1 to 1, with positive values indicating a positive correlation, negative values indicating...
Understanding negative correlation is important for investors since including assets in a portfolio that tend to move in opposite directions is key to achieving a well-diversifiedportfolio. In fact, it is because some asset classes—for instance, stocks and bonds—tend to exhibit a negative correlati...
How to interpret p-value: Even a low p-value is not necessarily proof of statistical significance, since there is still a possibility that the observed data are the result of chance. Only repeated experiments or studies can confirm if a relationship is statistically significant. ...
