Tweet You learn about statistical conclusion errors in every basic nursing research class and are expected to understand what these errors mean. Did I learn about this, you ask? Yes, yes, you did. Those are statistical conclusion errors.

And to be honest, it took me a long time before I could explain Type I and Type II errors to my research students without reading from my notes! Statistical conclusion errors are a result of the testing of the null hypothesis for a research study.

What is a Hypothesis? All a hypothesis is is an educated guess. All a hypothesis is is an educated guess!

Based on your knowledge of what you are researching, you make a statement of where you think the result of your research will lead, if there is enough literature for you to make a prediction. The alternative hypothesis is a statement of change; you may have more than one alternative hypothesis.

The null hypothesis is a statement of no change or no difference. There will be a change in the length of stay as a result of X. What is the Principle of Negative Inference? The principle of negative inference refers to how researchers make decisions about their research results.

It is a process of rejection — contrary to the way humans tend to think — which is why it is hard for some to get their heads around this concept. Innocent until proven guilty uses a similar principle Hopkins, a.

In research, we can disprove, but not prove, things. Therefore, we need something to disprove Hopkins, b. The null hypothesis is assumed to be TRUE. Again, most researchers are looking to show that their intervention is better than the standard of care SOCso they are hoping to reject the null.

Whether or not their research results are statistically significant or not! If the results are statistically significant — YAY!

Reject the null and say that your intervention is better than the standard of care. If the resulting p-value is greater than the one set by the researchers — Oh well. Fail to reject the null i.

Do another study with a larger sample size the most likely reason for not finding statistical significance and see what happens!

All hypothesis testing is testing of the NULL hypothesis! Hypothesis testing just means that the researcher will conduct their research study and make a decision about the veracity of the null hypothesis based on the research results.

Mistake or error of failing to reject a false null hypothesis saying there are no differences when there really are. Analogous to a Failed Alarm. When you look at the matrix below, reality is defined as either the null is true and no differences exist or that the null is false and differences really do exist.

If the reality is that the intervention would not make a difference in real life, then the researcher made a correct decision. If the reality is that the intervention would make a difference in real life, then the researcher made a correct decision.“Hypothesis is a formal statement that presents the expected relationship between an independent and dependent variable.”(Creswell, ) “A research question is essentially a hypothesis .
