1. What is Developmental Research? - Definition, Purpose & Methods
This lesson explores the basics of developmental research. Explore how cross-sectional and longitudinal studies can help researchers study the changes that occur as we age.
2. Quasi-Experimental Designs: Definition, Characteristics, Types & Examples
This lesson explores the basic definition of why there is the label of quasi-experimental design in addition to what types of designs are quasi-experimental.
3. Ex Post Facto Designs: Definition & Examples
This lesson explores what an ex post facto design is using two different examples. In addition, specific attention is paid to differentiating ex post facto from true experiment to reduce confusion.
4. Longitudinal Designs: Definition & Examples
This lesson discusses the uses and procedures in running a longitudinal design. In addition, we also explore some of the benefits and issues that can occur when using such a design.
5. Cross-Sectional Designs: Definition & Examples
This lesson explores the process and requirements in using a cross-sectional design. Two examples are used, one common and one uncommon, to demonstrate how cross-sectional designs can be used in quasi-experiments.
6. Pretest-Posttest Design: Definition & Example
This lesson explores the process and technique of using a pretest-posttest design in psychology. Two simple examples will allow you to understand how to apply this type of design in a future experiment.
7. Understanding the Time Dimension in Research
Something few researchers consider is how the passage of time may affect some research studies. This lesson explores a few different types of studies and how a researcher has to take the dimension of time into consideration when planning the whole experiment.
