A Practical Guide to Writing Quantitative and Qualitative Research Questions and Hypotheses in Scholarly Articles
Hypothesis-testing (Quantitative hypothesis-testing research) - Quantitative research uses deductive reasoning. - This involves the formation of a hypothesis, collection of data in the investigation of the problem, analysis and use of the data from the investigation, and drawing of conclusions to validate or nullify the hypotheses.
How to Write a Strong Hypothesis
6. Write a null hypothesis. If your research involves statistical hypothesis testing, you will also have to write a null hypothesis. The null hypothesis is the default position that there is no association between the variables. The null hypothesis is written as H 0, while the alternative hypothesis is H 1 or H a.
Research Questions & Hypotheses
The primary research question should originate from the hypothesis, not the data, and be established before starting the study. Formulating the research question and hypothesis from existing data (e.g., a database) can lead to multiple statistical comparisons and potentially spurious findings due to chance.
Research Hypothesis: Definition, Types, Examples and Quick Tips
3. Simple hypothesis. A simple hypothesis is a statement made to reflect the relation between exactly two variables. One independent and one dependent. Consider the example, "Smoking is a prominent cause of lung cancer." The dependent variable, lung cancer, is dependent on the independent variable, smoking. 4.
What is a research hypothesis: How to write it, types, and examples
Here are some good research hypothesis examples: "The use of a specific type of therapy will lead to a reduction in symptoms of depression in individuals with a history of major depressive disorder.". "Providing educational interventions on healthy eating habits will result in weight loss in overweight individuals.".
Quantitative Research
Quantitative Research. Quantitative research is a type of research that collects and analyzes numerical data to test hypotheses and answer ... To test a hypothesis: Quantitative research is often used to test a hypothesis or a theory. It involves collecting numerical data and using statistical analysis to determine if the data supports or ...
Quantitative data collection and analysis
A hypothesis is a statement that we are trying to prove or disprove. It is used to express the relationship between variables and whether this relationship is significant. It is specific and offers a prediction on the results of your research question. Your research question will lead you to developing a hypothesis, this is why your research ...
PDF Research Questions and Hypotheses
Quantitative research questionsinquire about the relationships among variables that the investigator seeks to know. They are used frequently in social science research and especially in survey studies. Quantitative hypotheses, on the other hand, are predic-tions the researcher makes about the expected relationships among vari-ables.
Hypothesis Testing
It is most often used by scientists to test specific predictions, called hypotheses, that arise from theories. There are 5 main steps in hypothesis testing: State your research hypothesis as a null hypothesis and alternate hypothesis (H o) and (H a or H 1). Collect data in a way designed to test the hypothesis. Perform an appropriate ...
Quantitative Research
Quantitative research is used when a researcher seeks to answer a specific research question or has a problem (hypothesis) that they want to investigate (or test). Hypothesis testing (sometimes called significance testing) in quantitative research is conducted on either the "null" or the "alternative" hypothesis. 8.1 The Null Hypothesis
What Is Quantitative Research?
Revised on June 22, 2023. Quantitative research is the process of collecting and analyzing numerical data. It can be used to find patterns and averages, make predictions, test causal relationships, and generalize results to wider populations. Quantitative research is the opposite of qualitative research, which involves collecting and analyzing ...
Constructing Hypotheses in Quantitative Research
Hypotheses are the testable statements linked to your research question. Hypotheses bridge the gap from the general question you intend to investigate (i.e., the research question) to concise statements of what you hypothesize the connection between your variables to be. For example, if we were studying the influence of mentoring relationships ...
What is Quantitative Research? Definition, Methods, Types, and Examples
Quantitative research is used to validate or test a hypothesis through the collection and analysis of data. (Image by Freepik) If you're wondering what is quantitative research and whether this methodology works for your research study, you're not alone. If you want a simple quantitative research definition, then it's enough to say that this is a method undertaken by researchers based on ...
What is a Hypothesis
Definition: Hypothesis is an educated guess or proposed explanation for a phenomenon, based on some initial observations or data. It is a tentative statement that can be tested and potentially proven or disproven through further investigation and experimentation. Hypothesis is often used in scientific research to guide the design of experiments ...
13 Different Types of Hypothesis (2024)
An empirical hypothesis is the opposite of a logical hypothesis. It is a hypothesis that is currently being tested using scientific analysis. We can also call this a 'working hypothesis'. We can to separate research into two types: theoretical and empirical. Theoretical research relies on logic and thought experiments.
Quantitative Research Hypothesis Examples
Whereas for qualitative research does not need to use statistical rules. In a quantitative study, the formulated statistical hypothesis has two forms, the null hypothesis (Ho) and the alternative hypothesis (Ha). In general, hypotheses for quantitative research have three types: Descriptive Hypothesis, Comparative Hypothesis, and Associative ...

Deductive reasoning: Quantitative research uses deductive reasoning, where the researcher tests a specific hypothesis based on prior knowledge and theory. Replication: ...

P-Values. The p-value of a hypothesis test is the probability that your sample data would have occurred if you hypothesis were not correct. Traditionally, researchers have used a p-value of 0.05 (a 5% probability that your sample data would have occurred if your hypothesis was wrong) as the threshold for declaring that a hypothesis is true.
After defining research objectives, the next significant step in primary quantitative research is data collection. This involves using two main methods: sampling and conducting surveys or polls. Sampling methods: In quantitative research, there are two primary sampling methods: Probability and Non-probability sampling.
Choosing the Right Statistical Test
Types of quantitative variables include: Continuous (aka ratio variables): represent measures and can usually be divided into units smaller than one (e.g. 0.75 grams). Discrete (aka integer variables): represent counts and usually can't be divided into units smaller than one (e.g. 1 tree). Categorical variables represent groupings of things ...
Your Ultimate Guide to Quantitative Research
While the quantitative research definition focuses on numerical data, qualitative research is defined as data that supplies non-numerical information. Quantitative research focuses on the thoughts, feelings, and values of a participant, to understand why people act in the way they do. They result in data types like quotes, symbols, images, and ...

Research Methods
The research methods you use depend on the type of data you need to answer your research question. If you want to measure something or test a hypothesis, use quantitative methods. If you want to explore ideas, thoughts and meanings, use qualitative methods. If you want to analyze a large amount of readily-available data, use secondary data.
Hypothesis
Types of Hypothesis. A hypothesis is a statement that can be tested and is often used in scientific research to propose a relationship between two or more variables. Understanding the different types of hypotheses is essential for conducting effective research. Below are the main types of hypotheses: 1. Null Hypothesis (H0)
Qualitative vs. Quantitative Research
Quantitative research Quantitative research is expressed in numbers and graphs. It is used to test or confirm theories and assumptions. This type of research can be used to establish generalizable facts. about a topic. Common quantitative methods include experiments, observations recorded as numbers, and surveys with closed-ended questions.
