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.

State your null and alternative hypotheses. Calculate the test statistic according to the research plan e. Usually done via a statistical software program, like SPSS Find the p-value for the test statistic once the test is run.
Make a logical conclusion about the significance of your study. Steps are easy. Statistical conclusion errors are those errors that researchers make unknowingly. Definitions There are two basic types of statistical conclusion errors that can be made: In both of these errors, a decision is made that turns out to be a mistake.
Mistake or error of rejecting a true null hypothesis saying there are differences when there really are not. Analogous to a False Alarm.
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 .
research hypothesis research question statistical hypothesis testability theory variable LEARNING OUTCOMES After reading this chapter, you should be able to do the following: • Describe how the research question and hypothesis relate to the other components of the research process.
• Describe the process of identifying and refining a research question or hypothesis. how to write a research hypothesis No comments A hypothesis is a description of a pattern in nature or an explanation about some real-world phenomenon . It can quite difficult to isolate a testable hypothesis after all of the research and study.
The best way is to adopt a three-step hypothesis; this will help you to narrow things down, and is the most foolproof guide to how to write a 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.
There are F ive Basic Steps to Hypothesis Testing (Cook, n.d.). Formulating hypothesis in nursing research 1.
Formulating hypothesis Maria Carmela L. Domocmat, MSN, RN Assistant Professor, Northern Luzon Adventist College 2. Hypothesis is your prediction of the relationship you expect to find.
A tentative prediction about the relationship between two or more variables.
