You calculate a correlation coefficient to summarize the relationship between variables without drawing any conclusions about causation. The value r = 0.02 in choice C is the closest to r = 0, so this correlation is the weakest among the group of other r values. Estimate the correlation coefficient. A low r2 means that only a small portion of the variability of one variable is explained by its relationship to the other variable; relationships with other variables are more likely to account for the variance in the variable. For high statistical power and accuracy, its best to use the correlation coefficient thats most appropriate for your data. As a rule of thumb, a correlation greater than 0.75 is considered to be a strong correlation between two variables. Correlation coefficients can range from: -1 to 1. To put this in perspective, if there are two variables with a correlation coefficient of -1, then that would be a strong negative correlation. a Negative Correlation Coefficient Mean verifying that the research meets ethical standards suggesting magazines that may be interested in publishing the researchCorrect!Correct!

Which of the following Why can't one state that a correlation between two variables indicates that a change in one causes a change in the other? When the coefficient comes down to zero, then the data is considered as not related. And in a field like technology, the correlation between variables might need to be much higher in some cases to be considered strong. For example, if a company creates a self-driving car and the correlation between the cars turning decisions and the probability of getting in a wreck is r = 0.95, this is likely too low for the car to be considered safe since the result of making the wrong decision can be fatal.
