A null hypothesis is what, the researcher tries to disprove whereas an alternative hypothesis is what the researcher wants to prove. A null hypothesis represents, no observed effect whereas an alternative hypothesis reflects, some observed effect. If the null hypothesis is accepted, no changes will be made in the opinions or actions. The Null and Alternative Hypotheses There are two hypotheses that are made: the null hypothesis, denoted H 0, and the alternative hypothesis, denoted H 1 or H A. The null hypothesis is the one to be tested and the alternative is everything else. In our example: The null hypothesis would be: The mean data scientist salary is 113,000 dollars. If your sample contains sufficient evidence, you can reject the null hypothesis and favor the alternative hypothesis.

This isn’t that bad of a problem; you could say the same about pretty much anything. My main issue with the null object pattern is that it amounts to little more than creating a new type of null without really solving the problem. The null hypothesis and alternative hypothesis are required to be fragmented properly before the data collection and interpretation phase in the research.

If a field can be null, then we can no longer rely on a.b to Jan 04, 2013 I don't like this code very much for two reasons: 1) The explicit null checks, and 2) The hard to read conditions. I figured there might be something in the Java 8 tool kit that would help me out. My first idea was to use Optional with the intention of being able to handle the 'null' condition more gracefully and in the hope it would result in a more pleasant usage pattern. Alternative definition is - offering or expressing a choice. How to use alternative in a sentence.
