There are five steps in the procedure for testing hypothesis. One must first state the research problem in a manner that clearly defines what is to be tested as well as identifying variables in the data collection. The population of interest and the parameters must be identified. An example might be "14 to 20 year old males prefer Pepsi over Coke."
The first step is to specify the null and alternative hypothesis. The null hypothesis and alternative hypothesis are opposites of one another. If the hypothesis is "14 to 20 year old males prefer Pepsi over Coke," the null hypothesis is "14 to 20 year old males do not prefer Pepsi to Coke." A null hypothesis would reflect that "there is no observed effect for (the) experiment," (Taylor, 2014) or in other words, there is no correlation between 14 to 20 year old males and their preference for Pepsi over Coke. The mathematical formulation for a null hypothesis ...
