What is a strong negative correlation?
A perfect negative correlation has a value of -1.0 and indicates that when X increases by z units, Y decreases by exactly z; and vice-versa. In general, -1.0 to -0.70 suggests a strong negative correlation, -0.50 a moderate negative relationship, and -0.30 a weak correlation.
What is an example of a correlational study?
If there are multiple pizza trucks in the area and each one has a different jingle, we would memorize it all and relate the jingle to its pizza truck. This is what correlational research precisely is, establishing a relationship between two variables, “jingle” and “distance of the truck” in this particular example.
What is an example of a weak correlation?
In technology fields, the correlation between variables might need to be much higher to even be considered “weak.” For example, if a company creates a self-driving car and the correlation between the car’s turning decisions and the probability of avoiding a wreck is r = 0.95, this may be considered a “weak” correlation …
