Negative correlation coefficients indicate that as the values for one variable increase, the values for the second variable decrease. Positive correlation coefficients indicate that as one variable increases in value, the value of the second variable as well. Spearman's rho and Kendall's tau, both...
aThe Spearman’s correlation coefficients in Table 3 indicate that the three safety management categories were significantly related to each other and to project performance in the predicted direction. 用矛者的相关系数在表3表明三个安全管理类别在被预言的方向显著互相和与项目表现有关。[translate]...

Positive coefficients indicate that when the value of one variable increases, the value of the other variable also tends to increase. Positive relationships produce an upward slope on a scatterplot. Negative coefficients represent cases when the value of one variable increases, the value of the othe...
5.1 Correlation coefficients The correlation coefficients or coherence coefficients between different polarizations are very important polarimetric parameters because they are sensitive to many target parameters. For example, the HH-VV correlation coefficient has been found to be sensitive to dielectric constan...
A picture can be worth 1,000 correlation coefficients! Scatterplots, and other data visualizations, are useful tools throughout the whole statistical process, not just before we perform our hypothesis tests. In fact, it’s important to remember that relying exclusively on the correlation coefficient...
Thinking about the numeric value of a correlation coefficient as a percentage. A 20% move higher for variable X would equate to a 20% move lower for variable Y. A strong correlation doesn't indicate a causal relationship. Extreme Correlation Coefficients ...

Different types of correlation coefficients are used to assess correlation based on the properties of the compared data. By far the most common is thePearson coefficient, known as “Pearson’s R,”which measures the strength and direction of a linear relationship between two variables. The Pearson...
Coefficients of simple correlations indicate the presence of very strong to almost complete, statistically very significant positive correlations, so these effects were expected. Plant height and number of leaves were not directly but indirectly statistically significant to yield of green biomass and ...
