It is predictive in nature and typically used when significant knowledge already exists on the subject which allows the prediction to be made.
Therefore, how you ask your question will influence your subsequent data analysis. In the first example, the research question is not simply interested in the daily calorific intake of American men and women, but what percentage of these American men and women exceeded their daily calorific allowance.
In the examples below, we have illustrated the name of the dependent variable and highlighted how it would be written out in the blue text. A research question helps us define what we hope to learn when we conduct our study.
It establishes which part of the previously identified problem our study will try to solve for the reader. In quantitative research, you usually work with at least two variables.
Once you complete your list, review your questions in order to choose a usable one that is neither too broad nor too narrow. The answer often leads to other questions — questions which need to be the scope of a new study; a quantitative or a qualitative study based on the questions that are unearthed.
Take the following examples: Some of these starting phrases are highlighted in blue text in the examples below: It is written as a question and is inquisitive in nature. But remember, any new question s that arise should be undertaken separately from your first study.
To what extent can a certain diet predict the onset of a stroke What makes a good quantitative research question? THIRD Identify the group s you are interested in All descriptive research questions have at least one group, but can have multiple groups. Handbook in research and evaluation.
Predictive questions and studies are always highly controversial, be sure to cover all your bases when trying to predict something, more often than not there are about 3, variables that come together to create an outcome and trying to link only a few of those to always get the same outcome can be a huge mistake especially in social science.
Predictive Questions Predictive questions are questions that try to predict no way! How many calories are consumed per day by American men and women? The next step is to do preliminary research on the general topic to find out what research has already been done and what literature already exists.
Is there a significant difference in reading scores between children who read five books a month and children who read two books a month? Name of the dependent variable How the dependent variable is written out Daily calorific intake How many calories do American men and women consume per day?
Causal Predictive Causal Questions Causal questions are exactly what they sound like — a question that tries to compare two or more phenomena and determine or at least suggest a relationship between the two or more.
Administrators who provide wellness programs for their employees receive higher employee ratings on selected leadership qualities than administrators who do not provide wellness programs.
On the other hand, a focused question such as "What are the pros and cons of Japanese management style? Consuming vitamin C supplements will reduce the incidence of the common cold in teenagers. How many calories are consumed per day by American men and women?
These questions often involve the manipulation of an independent variable and the comparison of the outcome of this manipulation. Again, the name of this dependent variable makes it easy for us to understand that we are trying to measure the often i.Quantitative methods emphasize objective measurements and the statistical, mathematical, or numerical analysis of data collected through polls, questionnaires, and surveys, or by manipulating pre-existing statistical data using computational techniques.
Quantitative research focuses on gathering. A research question is the fundamental core of a research project, study, or review of literature. It focuses the study, determines the methodology, and guides all stages of inquiry, analysis, and reporting.
Research Questions and Hypotheses - This book chapter takes an in-depth look at the principles used to design and write research questions and hypotheses for qualitative, quantitative and mixed methods research and describes the differences in approaches based upon the type of research.
A quantitative research question is usually followed by a hypothesis — this is a prediction of what we think our study will find; a statement that answers the initial speculative research question.
In quantitative research, you usually work with at least two variables. Write out the problem or issues you are trying to address in the form of a complete research question. In the previous section, we illustrated how to write out the three types of research question (i.e., descriptive, comparative and relationship-based research questions).
Formulating a quantitative research question can often be a difficult task. When composing a research question, a researcher needs to determine if they want to describe data, compare differences among groups, assess a relationship, or determine if a set of variables predict another variable.Download
