quantitative research questions ppt

Researchers are advised to carefully evaluate research questions, validation methods, and ethical guidelines. To further the field of research methodology, future research directions should concentrate on interdisciplinary collaboration, creative methodologies, and integration of quantitative and qualitative approaches.

Quantitative methods are a collection of tools we can use to investigate research questions and theories. Quantitative data is a collection of information structured in terms of units and variables. We can summarise variables by examining measures of central tendency.

This document discusses research questions and hypotheses. It defines a research question as a provisional answer that must be tested, and a hypothesis as a tentative conjecture that predicts an observation.

Quantitative research uses computational techniques to objectively investigate observable phenomena through numerical analysis of data. It aims to gather unbiased numerical results that can be generalized to a larger population to explain ...

1. Quantitative research uses statistically analyzed numerical data to investigate observable phenomena in an objective and systematic manner. 2. It is characterized by large sample sizes, visual data presentation, faster data analysis and collection, generalizable and reliable data, and replication. Its strengths include replicable findings, establishing cause and effect, and predicting ...

Central Question Guidelines. 1. Begin with "How" or "What". Avoid "Why". 2. List the central phenomenon you plan to explore. 3. Identify the participants and research site [this is a quantitative term that implies cause and effect] Qualitative Central Question Script:

The first step is to determine which type of quantitative question you want to add to your study. There are three types of quantitative questions: Descriptive. Comparative. Relationship-based.

Quantitative research: is concerned with objectivity, tight controls over the research situation, and the ability to generalize findings. Qualitative research: is concerned with the subjective meaning of an experience to an individual. Concepts are abstractions of particular aspects of human behavior or characteristics (e.g., pain, weight).

Steps in Quantitative Research 7. Formulate the Hypothesis or Research Question • A hypothesis predicts the relationship between two or more variables. • The hypothesis contains the population and the variables. • Independent Variable is the "cause" or the variable that is thought to influence the dependent variable.

Title: Introduction to Quantitative Research 1 Introduction to Quantitative Research. Elin Driana, Ph.D; 2 Research. a systematic attempt to provide answers to questions (Tuckman, 1999, p. 4) the more formal, systematic, and intensive process of carrying on a scientific method of analysis (Best and Kahn, 1986, p. 18). 3 Quantitative Research

Aim of the study: The present study aimed to evaluate the effect of cognitive behavioral (CB) intervention on improving sleep quality in older adults. Design: A quasi-experimental pretest-and-posttest design was utilized to conduct this study. Setting: The study was conducted in the geriatric social club in Zagazig City.

5. Analyzing and Interpreting data Quantitative Research Qualitative Research • Data analysis tends to consist of statistical analysis. • Describing trends, comparing group differences, relating variables. • Interpretation tends to consist of comparing results with prior predictions and past research. • Text analysis.
