Psychological Terms Flashcards
independent variable
The variable that researchers manipulate or control in an experimental study to explore its effects.
It’s called “independent” because it’s not influenced by any other variables in the study.
factor
independent variable in an experiment, especially those that include two or more independent variables
Factorial design
A research design that includes two or more factors.
Quasi-independent
Attributes cannot be manuablated in an experiment such as gender , age
Main effect
research refers to the impact of one independent variable on the dependent variable
Mean difference:
difference between the average values of two distinct groups in a clinical trial or research study.
If we’re comparing the effectiveness of a new drug (experimental group) to a placebo (control group) in reducing blood pressure, the mean difference would reveal the absolute difference in average blood pressure readings between these two groups
the mean difference helps researchers understand the impact of an intervention by directly comparing the means of relevant outcome measures
Between subject design
Different group of people given the same or different condition in an experiment, to test their difference
within-subject design
The same group of people receive different tests to see different outcomes
The general disadvantage of between-subject design
Individual differences can affect the result and make it harder to determine the true effect of the independent variable.
Differential design
study two or more different groups based on preexisting attributes and conditions, such as age and gender, without manipulating conditions and variables.
advantages of using qualitative research over quantitive
Qualitative research helps us to understand the topic from the perspective of the parents of these adolescents.
As researchers, we might not know what questions to ask on a survey if we really don’t know much about these parents.
Qualitative research
Qualitative research is a methodological approach that involves collecting and analyzing non-numerical data to understand concepts, opinions, or experiences.
It’s used to gain in-depth insights into a problem or to generate new ideas for research.
Quantitivity research
Quantitative research is a systematic approach that focuses on collecting and analyzing numerical data to uncover patterns, trends, and correlations.
It’s characterized by the use of statistical methods to quantify variables and often employs surveys, experiments, or observational studies to gather measurable data.
The process used to come up with themes in qualitative research by continually referring back to the text to see what the participants actually said?
iterative
The name of the committee that would have had to approve this study beforehand in order to protect the welfare of the participants?
The Institutional Review Board.
