December 13, 2023 - Predictions typically arise from a thorough knowledge of the research literature, curiosity about real-world problems or implications, and integrating this to advance theory. They build on existing literature while providing new insight. ... The research hypothesis is often called the alternative or experimental hypothesis in experimental research.

November 21, 2024 - A theory is “a reasoned and precise speculation about the answer to a research question” (King, Keohane, and Verba 1994). Good theories are clear and specific about how the independent variable causes or affects the dependent variable. Dependent variable: the outcome we are interested in that depends on another variable. What we are trying to explain. Independent variable: The variable causing or affecting the outcome. What we think is explaining the dependent variable. ... “A hypothesis is a statement of the relationship that you expect to find between the dependent variable and the independent variable” (Powner 2014).

Hypothesis Explanation: The dependent variable (student reading comprehension scores) is the focus, and the hypothesis explores how changes in the independent variable (teacher-led instructional time) affect it. ... In X-centered research designs, the independent variable is specified in the research question. Theories are used to determine potential dependent variables and the causal mechanisms at play. Example: “Implementing technology-based learning tools (IV) is likely to enhance student engagement in the classroom (DV), because interactive and multimedia content increases student interest and participation.”

November 5, 2009 - It is a preliminary answer to your question that helps guide the research process. Consider a study designed to examine the relationship between sleep deprivation and test performance. The hypothesis might be: "This study is designed to assess the hypothesis that sleep-deprived people will perform worse on a test than individuals who are not sleep-deprived." In the scientific method, whether it involves research in psychology...

Hypothesis development and testing in psychology is a systematic approach used to answer questions about human behavior. It begins with observations that lead to inquiries, such as whether caffeine enhances alertness. Researchers propose multiple hypotheses and generate predictions based on these ideas, then collect data to evaluate which hypothesis aligns with the observed outcomes.

October 7, 2025 - This step provides essential background information to begin your research. For example, if you notice that an office’s vending machine frequently runs out of a specific snack, you may predict that more people in the office choose that snack over another. After identifying a subject and recognizing a pattern, the next step is to ask a question that your hypothesis will answer.

Hypothesis as Question: According to District of Columbia v. Heller should states have the · power to uphold and regulate individual "Right to Bear Arms"?

The top three priorities for carotid disease are below and include an example for a question that is descriptive, relationship and comparative: Can doctors accurately predict which people with carotid artery disease are most at risk of a stroke? - Descriptive · Is there an association between carotid disease and cognitive decline? - Relationship · What is the optimal management of patients with carotid disease using individualised risk benefit ratios? - Comparative · Proposing a hypothesis to a research question can be a little more challenging.

September 14, 2013 - In this example, the independent variable is the temperature and the dependent variable is melting time. They are both objective and measurable. The hypothesis is testable by carrying out the activity and gathering data that may support or refute the statement. A researcher may use a research question and a hypothesis within the same study.

October 10, 2024 - Here are some example research questions and hypotheses: Question: Is there an association between number of hours spent on social media per day and mental health? Hypothesis: There is a negative association between number of hours spent on ...

The research or clinical hypothesis is developed from the research question and then the main elements of the study — sampling strategy, intervention (if applicable), comparison and outcome variables — are summarized in a form that establishes the basis for testing, statistical and ultimately clinical significance.3 For example, in a research study comparing computer-assisted acetabular component insertion versus freehand acetabular component placement in patients in need of total hip arthroplasty, the experimental group would be computer-assisted insertion and the control/conventional group would be free-hand placement.

This process is usually conceptualized as a cycle because the researcher can then derive a new hypothesis from the revised theory, conduct a new empirical study to test the hypothesis, and so on. As Figure 2.2 shows, this approach meshes nicely with the model of scientific research in psychology presented earlier in the textbook—creating a more detailed model of “theoretically motivated” or “theory-driven” research. Figure 2.2 Hypothetico-Deductive Method Combined With the General Model of Scientific Research in Psychology Together they form a model of theoretically motivated research. As an example, let us consider Zajonc’s research on social facilitation and inhibition.

A hypothesis states your predictions about what your research will find. It is a tentative answer to your research question that has not yet been tested.

September 15, 2021 - A hypothesis is your first expectation for a specific research question before doing the research. For example, you do research on the relationship between hours worked and tiredness, your hypothesis could be: there is a positive relation between hours worked and tiredness.

A phenomenological example is, “What · is it like for a mother to live with a teenage child who is dying of cancer?” · (Nieswiadomy, 1993, p. 151).
