Research begins with the hypothesis, gathers and examines data, and then evaluates the validity of the hypothesis with the data gathered. In the article, the question "Does increasing study time affect student grades? Qualitative research is an explanatory, narrative, and subjective examination of observed and reported behavior. Qualitative research would begin by noting that students who stayed after class with their professor scored higher an their exams, and would possibly conclude that the higher scores and time spent with the professor correlated with a deeper interest with the material itself.

Research Questions and Hypotheses The purpose of this module is to discuss research questions and research hypotheses and to provide definitions, comparisons and examples of both. Define research question and research hypothesis. Explain the difference between a research question and a research hypothesis and describe the appropriate use of each.
Describe the purpose of each and understand the importance of a well-developed question or hypothesis. Provide examples of research questions and research hypotheses. Used to analyze and investigate a topic. It is written as a question and is inquisitive in nature. A properly written question will be clear and concise. It should contain the topic being studied purpose , the variable s , and the population.
Three main types of questions: Types of quantitative research question. This is a critical component of experimental , quasi-experimental and relationship-based research designs [see the section on Quantitative research designs to learn more]:. Whilst we describe these types of variables in detail in the article, Types of variables , you need to be aware of the differences between independent and dependent variables, and categorical and continuous variables.
There are two groups of variables that you need to know about: We use the word groups of variables because both categorical and continuous variables include additional types of variables. Categorical variables , also known as qualitative or discrete variables , can be further classified a being nominal , dichotomous or ordinal. On the other hand, continuous variables , also known as quantitative variables , can be further classified a being either interval or ratio. For example, the variable gender male or female in the Facebook example is a dichotomous variable.
When performing quantitative analysis on the data you collect during the dissertation process, you need to understand what type of categorical or continuous variables you are measuring. A variable is not only something that we measure , but also something that we can manipulate and something we can control for. For this reason, we distinguish between independent and dependent variables.
An independent variable , sometimes called an experimental or predictor variable , is a variable that is being manipulated in an experiment in order to observe the effect on a dependent variable , sometimes called an outcome variable. Understanding which of the variables you are studying are the independent , dependent and control variables is necessary in order to know how to structure and write up your research questions.
What types of quantitative research question i. Armed with this knowledge, you now need to think about how to structure your quantitative research questions; that is, how you can write out your research questions in a way that the reader can clearly understand what you are trying to achieve. There is no "one best way" to structure a quantitative research question. However, we recommend an approach that is based on three steps:. Choose the type of quantitative research question you are trying to create.
The type of quantitative research question that you use in your dissertation i. Therefore, in order to know how to structure your quantitative research question, you need to start by selecting the type of quantitative research question you are trying to create: Quantitative research questions tend to start with words like "What are" , "How do" , "Does" , "How often" , amongst others.
Which words you start with will depend on the type of quantitative research question you are trying to create i. The type of quantitative research question you are trying to create i.
As a general rule, we suggest that independent variables are set out first, followed by dependent variables, and then control variables if there are any. In the section, How to structure quantitative research questions , we discuss these three steps in more detail, providing examples along the way. Quantitative research questions and research hypotheses are designed to accomplish different tasks:. Explain the purpose of the research. In other words, what issue or problem is the research trying answer?
In terms of quantitative research questions, the type of research question i. Explain the predictions being made or otherwise by the researcher based on specific hypothesis statements.
A complete hypothesis should include: the variables, the population, and the predicted relationship between the variables. Commonly used in quantitative research, but not qualitative research which often seeks answers to open-ended questions.
A hypothesis is a tentative assumption in the form of a statement or a question that a research effort is designed to answer. In quantitative research, there are two hypothesis statements.
In qualitative research, hypotheses are not tested. However, hypotheses or "theories" about social phenomena can "emerge" from the research data and findings. Grounded theory is a very good example of this. For more on grounded theory, check out: Corbin and Strauss () Qualitative Sociology 13(1). Aug 18, · Fundamentally, a quantitative hypothesis is a statistical, numerical, objective examination of cause and effect. Research begins with the hypothesis, gathers and examines data, and then evaluates the validity of the hypothesis .
Quantitative research questions: When performing quantitative analysis on the data you collect during the dissertation process, (or otherwise) by the researcher based on specific hypothesis statements. These hypothesis statements set out what problem or issue the research is trying to answer. This short piece of writing discusses quantitative research questions and hypothesis on this student’s research. According to Joyner, Rouse.
