It is observable that there exists a weak positive correlation between Claims and the rest of the dependent variables for each one of the coverages, and the empirical values are near the theoretical values. These figures were calculated before incorporating the effect of the explanatory variables ...

There was no correlation between the carnitine level and the percentage of sperm with progressive motility as well as sperm concentration in the two groups. The area under the ROC curve was 0.592, cut-off value was 380.9, there was a weak positive correlation between the carnitine level and ...
Does a Correlation Coefficient of -0.8 Indicate a Strong or Weak Negative Correlation? A correlation coefficient of -0.8 indicates an exceptionally strong negative correlation. The two variables tend to move in opposite directions. The closer the coefficient is to -1.0, the stronger the negative rel...
There was a weak positive correlation between MDW and qSOFA in the non-infective group (r(1500) = 0.09, p < 0.001) and no significant correlation in the infective group based on Spearman’s rank calculation. However, in contrast to qSOFA score elevation (2 and 3 points) from ...
Linear regression based on the 12-point method showed that bone cement distribution had a nearly negative correlation with re-collapse of augmented vertebra, but a weak positive correlation with new fracture. The two curves intersected at a score of 10, indicating that patients with this score ...
-1.0 to -0.70 suggests a strong negative correlation, -0.50 a moderate negative relationship, and -0.30 a weak correlation. Remember that even though two variables may have a very strong negative correlation, this observation by itself does not demonstrate a cause-and-effect relationship between th...
Looking at the correlation matrix, it seems that mpg has a strong negative correlation with #cylinders, displacement, horsepower, and weight. In comparison, it has a weak positive correlation with acceleration. Summary The CORR_MATRIX function provides an easy way to calculate the correl...
Using statistical software, calculate the chosen correlation coefficient. A value close to +1 or -1 indicates a strong relationship, whereas a value near 0 suggests a weak relationship. Example Output: Pearson's r = 0.85 p-value < 0.001 This output indicates a strong positive relationship that...
