Descriptive Research Design
What type of questions does descriptive research design aim to answer?
What occur, when occur, why occur, how occur
When is descriptive research design especially effective?
When the area has been previously studied
What is the purpose of inter-relational research design?
To establish correlations and make predictions
What does epidemiological research design focus on?
Disease patterns and risk factors in populations
What type of research design involves observing the same subjects over a period of time?
Longitudinal Developmental Research Design
What is the primary focus of survey research design?
To collect data from a sample of individuals to describe and draw conclusions about a population
In what type of research design are correlations established between variables?
Inter-Relational Research Design
What is the main characteristic of epidemiological research design?
Focuses on disease patterns and risk factors in populations
What type of studies compare and contrast two or more variables on the same phenomena?
Comparative studies
Which research design aims to identify and explore existing phenomena and related factors?
Explorative design
What does correlational design describe?
A linear relationship, but does not suggest a cause-and-effect relationship
What is the typical analysis involved in research design types and characteristics?
Descriptive statistics and textual analysis
What is the aim of predictive studies?
To identify pre-existing characteristics that predict a relationship with dependent variables
What is the disadvantage of descriptive research design?
Inability to make conclusions about relationship studies
What is the focus of univariant descriptive design?
To describe the frequency of a phenomenon and may involve multiple variables
What is the advantage of correlational research design?
It demonstrates the degree of relationship between variables
What does interrelational studies provide a deeper insight into?
The phenomenon of interest and trace interrelationships between variables
What does comparative studies involve?
Comparing and contrasting two or more variables on the same phenomena
What type of analysis is typical in predictive studies?
Regression, multiple regression, and discriminant analysis
Which type of study examines the distribution and causes of diseases in a population?
Epidemiological studies
What do longitudinal surveys study?
The same group of subjects over a period of time
What do non-experimental design studies require?
No experiment and are closest to real-life situations
What is a disadvantage of non-experimental research design?
Less reliable data and nonrandomly selected groups
What do cohort studies use to investigate the occurrence of a disease?
Longitudinal approach
What do developmental studies describe?
Developmental change and sequencing of behaviors over time
What type of survey design collects information from a homogenous group of subjects?
Descriptive survey
What do cross-sectional surveys study?
A phenomenon at one point in time
What do longitudinal studies observe and collect data on?
Variables without trying to influence those variables
Study Notes
Research Design Types and Characteristics
- Predictive studies involve shorter time for predictions, whereas longer time allows for more variables to influence the prediction.
- Typical analysis in predictive studies includes regression, multiple regression, and discriminant analysis to compare different user groups.
- Developmental studies describe developmental change and sequencing of behaviors over time, widely used in education, nutrition, epidemiology, and behavioral sciences.
- Types of developmental designs include cross-sectional and longitudinal designs, used to examine data at one point in time or over an extended period.
- Epidemiological studies investigate the distribution and causes of diseases in a population, using cohort and case-control studies.
- Cohort studies use a longitudinal approach to investigate the occurrence of a disease in individuals with presumed causes, while case-control studies investigate causes after the occurrence.
- Survey design is a popular method to collect information from a homogenous group of subjects, using descriptive, exploratory, comparative, and co-relational surveys.
- Cross-sectional surveys study a phenomenon at one point in time, while longitudinal surveys study the same group of subjects over a period of time.
- Longitudinal studies observe and collect data on variables without trying to influence those variables, used to study morbidity, mortality, and treatment adherence.
- Non-experimental design studies require no experiment and are closest to real-life situations, suitable for fields like psychology, sociology, education, and nursing.
- Disadvantages of non-experimental research design include less reliable data and nonrandomly selected groups, affecting the authenticity and generalizability of study results.
- Nonexperimental studies are conducted for comparative purposes using nonrandomly selected groups, which may not be homogeneous and tend to be dissimilar in different traits or characteristics, affecting the authenticity and generalizability of the study results.
