The null hypothesis is paired with an alternative: (a) The null states that there is “no pattern”; i.e., no difference between (2) or among (>2) groups, or no relationship between two continuous variables. (b) The alternative states that a pattern does exist; i.e., there are distinct differences between or among 9/7/2015 · It is defined as the prediction that there is a measurable interaction between variables It is also called as “MANTAINED hypothesis” or “RESEARCH hypothesis” It is denoted by H(a) Null hypothesis is opposed by alternative hypothesis.
