null hypothesis

If your proposed model for a data set says that the value of x is affecting the value of y, then the null hypothesis—the model you're comparing your proposed model with to check whether x really is affecting y—says that the observations are all based on chance and that there is no effect. “The smaller the P-value computed from the sample data, the stronger the evidence is against the null hypothesis.”[shin] See also P value
