Which research studies the same groups of participants overtime?
A longitudinal study
can be used to discover relationships between variables that are not related to various background variables. This observational research technique involves studying the same group of individuals over an extended period.
Which research study follows and retest the same people over time?
Longitudinal
and Cross-Sectional Research. Sometimes we want to see how people change over time, as in studies of human development and lifespan. When we test the same group of individuals repeatedly over an extended period of time, we are conducting longitudinal research.
What type of research studies a group of individuals or subjects who are the same age over a period of many years watching for changes as the subjects mature and age?
Longitudinal research designs
are used to examine behavior in the same individuals over time. For instance, with our example of studying intelligence and aging, a researcher might conduct a longitudinal study to examine whether 20-year-olds become less intelligent with age over time.
Which type of research involves monitoring different groups of people of different age?
cross-sectional research

. Dr. Matter is interested in knowing more about brain injury to the occipital vortex, and he studies patients individually in order to gain in-depth knowledge about their behaviors.
Is a reduction in the number of research participants?
Explanation:
Attrition
refers to the participants leaving the research study due to different reasons. Here, it must be clarified that attrition happens in almost every research. Also, attrition happens only when the participants leave themselves and not when they are removed by the researchers.
What is the quickest and least expensive way to study development?
Why would a scientist conduct

Is conducted in order to determine whether there are meaningful differences between two groups in a study?
Once data is collected from both the experimental and the control groups,
a statistical analysis
is conducted to find out if there are meaningful differences between the two groups. A statistical analysis determines how likely any difference found is due to chance (and thus not meaningful).
What type of research is most controlled?
- Experiments are generally the most precise studies and have the most conclusive power. …
- A well-designed experiment has features that control random variables to make sure that the effect measured is caused by the independent variable being manipulated.
What type of study is a descriptive study?

one in which information is collected without changing the environment

What are the two main reasons to conduct a factorial study?
What are two reasons to conduct a factorial study? –

. -Does the effect of the original independent variable depend on the level of another independent variable?
What is a two group design?

when a researcher divides his or her subjects into two groups and then compares the results
. The two groups usually consist of a control group, who does not get the treatment, and a treatment or experimental group, who does get the treatment.
Which type of research has only one subject?
“Single subject research (also known as
