One of your friends is reading a newspaper article, which notes that, in rats, there is a positive significant relationship between sugar consumption and obesity. the more sugar a rat consumes, the higher its overall body mass. your friend asks you what it means that the results of this experiment were statistically significant. what do you tell him?

The answer is: The fact that rats that consume more sugar have higher body masses is not due to chance. In addition, statistically significant is the probability that an affiliation among two or more variables is triggered by something other than random chance. The statistical hypothesis analysis is used to define whether the outcome of a data set is statistically important.
