What is the incidence of blood clots from COVID-19 in females over the age of 35?
The
above question is an example of a research question. A research
question consists of three parts and guides the methods and approaches
in which you will study the question to find answers. The research
question includes: the question, the topic, and the population or
variables. In the example provided above, the question is examining the
prevalence of blood clots from severe COVID-19 in a selected population.
From this question, the variables can be assessed, considerations can
be analyzed, and populations can be sampled in order to guide the
research.
During Week 2, you developed a research problem
statement based on a topic of interest to you or your specific area of
practice. Using this research problem statement, you will develop a
research question. “A research question is a concise, interrogative
statement that is worded in the present tense and includes one or more
of a study’s principal concepts or variables” (Gray & Grove, 2020).
These questions typically point to the type of study that will be
conducted and serves as a guide for the research.
For this
Discussion, reflect on your research problem statement. Consider the
independent and dependent variables of your research problem through the
construction of a research question. Reflect on the potential levels of
measurement for your variables and the rationale for the labels, as
well as consider the advantages and challenges that you might experience
in the statistical analysis of your proposed variables.
To prepare:
Review your research problem statement from Week 2 to develop your research question.
Review the Learning Resources on how to describe variables.
Consider the levels of measurement for your variables: nominal, ordinal, interval, or ratio.
After
reviewing your research question and considering the levels of
measurement, analyze your classification for each variable. What was
behind your reasoning for labeling the variables? How might the data be
analyzed based on these labels?
Consider advantages and challenges that you might encounter in the statistical analysis of your proposed variables.
Post your research question and describe the
independent and dependent variables. Then, identify the level of
measurement of both your independent and dependent variables. Provide a
brief rationale for your classification of each variable. Be specific.
Explain considerations of analyzing data related to each variable based
on its level of measurement. Be sure to include any advantages or
challenges that you might encounter in your statistical analysis of each
variable and explain why.
