Longitudinal Design. A special kind of systematic observation, used by correlational researchers, that
involves obtaining measures of the variables of interest in multiple waves over time
.
Is a manipulated experimental factor that the experimenter changes to see what its effects are?
| Term Theory Definition A broad idea or set of closely related ideas that attempt to explain observations. | Term Independent Variable Definition A manipulated experimental factor; the variable that the experimenter changes to see what its effects are. | Term Dependent Variable Definition The outcome |

What is correlational research quizlet?
Correlational Research. refers to
any study in which two or more variables are measured to determine if the variables are related
.
What can correlational studies tell us?
Researchers use it to
measure and spot historical patterns between two variables
. A correlational study may show a positive relationship between two variables, but this can change in the future. Dynamic: The patterns between two variables from correlational research are never constant and are always changing.
What is a correlational study in psychology?
Correlational studies are a type of research often used in psychology, as well as other fields like medicine. … Researchers use
correlations to see if a relationship between two or more variables exists
, but the variables themselves are not under the control of the researchers.
What is the purpose of correlational research quizlet?
What is correlational research? What is the purpose? -The researcher collects data to determine whether and to what degree a relationship exists between two or more quantifiable variables. -The purpose is
to determine relationships and make predictions
.
Why can’t correlational research tell us two variables go together quizlet?
The reasons why we can’t show causation from correlation are basically that correlational research allows us to measure the strength of the relationship between two variables,
it does NOT tell us whether changing one variable will cause changes in another
, and CORRELATION IS NOT CAUSATION, along with the direction-of- …
Which of the following receives the treatment in an experiment?
Control groups are essential to experimental design. When researchers are interested in the impact of a new treatment, they randomly divide their study participants into at least two groups:
The treatment group (also called the experimental group)
receives the treatment whose effect the researcher is interested in.
What is conceptualized as the potential cause?

Which of the following is an advantage of using a double blind experiment?
The double-blind procedure helps
minimize the possible effects of experimenter bias
. 2 Such biases often involve the researchers unknowingly influencing the results during the administration or data collection stages of the experiment.
What are the strengths and weaknesses of correlational research?
| Strengths: Weaknesses | Calculating the strength of a relationship between variables. Cannot assume cause and effect, strong correlation between variables may be misleading. |

When would you use a correlational study?
In cases where carrying out experimental research is unethical, correlational research can be
used to determine the relationship between 2 variables
. For example, when studying humans, carrying out an experiment can be seen as unsafe or unethical; hence, choosing correlational research would be the best option.
What are the characteristics of a correlational study?
Correlational Research is a non-experimental research method. In this research method, there is no manipulation of an independent variable. In correlational research, the researcher studies
the relationship between one or more quantitative independent variables and one or more quantitative dependent variables
.
What are the 5 types of correlation?
- Pearson Correlation Coefficient.
- Linear Correlation Coefficient.
- Sample Correlation Coefficient.
- Population Correlation Coefficient.
What are the 4 types of correlation?
Usually, in statistics, we measure four types of correlations:
Pearson correlation, Kendall rank correlation, Spearman correlation, and the Point-Biserial correlation
.
What is an example of correlation in psychology?
An example of positive correlation would be
height and weight
. Taller people tend to be heavier. A negative correlation is a relationship between two variables in which an increase in one variable is associated with a decrease in the other.
