Fundamentals of Psych Research
What is the scientific study of mental processes and behavior?
What is the scientific method used in psychology to examine the relationship between two or more variables?
Correlational Research
How do you find the median in a data set?
Put all numbers in order and find the middle number.
Harm
What is random sampling?
What is the "I-knew-it-all-along" bias?
As the amount of sleep increases, the higher the student's GPA gets. This is an example of what type of correlation?
Positive - both going up
A symmetrical distribution of data (where the mean median and mode are all the same) makes what shape?
a bell curve
Give an example of deception in a research study
answers will vary
What research technique is used to investigate cause-and-effect relationships between variables.
experiment
What is the tendency of individuals to respond in a manner that is viewed favorably by others or conforms to social norms, rather than providing honest or accurate answers.
Social Desirability Bias
A perfect correlation is what?
What are the three Measures of Central Tendency ?
Mean, Median, and Mode
What is the point of the IRB?
To review and approve research proposals to ensure that they meet ethical standards and protect the rights and welfare of research participants.
Is an operational definition quantitative or qualitatve?
quantitative
What is a con to case studies?
Findings from case studies may not always be generalizable to broader populations due to their focus on specific cases.
r= +0.67 would indicate what type of correlation?
What statistical measure tells us how spread out the scores are from the average, or mean?
Standard deviation
Debriefing
Explain the difference between Independent and dependent variable
IV = manipulated / DV = measured
What is the difference between quantitative and qualitative data?
Quantitative Data is numbers-based information gathered from surveys, tests, or experiments. (It helps us understand patterns and relationships in a precise way.)
Qualitative data is not about numbers but gives deeper insights into complex topics. (Information collected through methods like interviews or observations, focusing on people's experiences and behaviors)
Give an example of a negative correlation between two variable.
Variables move in opposite directions (answers vary)
What is a Meta- analysis?
The statistical analysis of multiple research studies on the same topic to draw overall conclusions. It combines data from various studies to increase the overall sample size and statistical power.
What is the placebo effect?
the phenomenon where individuals experience improvement in their condition solely because they believe they are receiving a beneficial treatment, rather than due to any active ingredient or physiological mechanism in the placebo itself.
1. Dr. Alber is conducting a study to examine the impact of background music on students' concentration levels. She divides a group of 100 students into two groups: one group studies with classical background music playing, while the other group studies in complete silence. After a 30-minute study session, each student takes a standardized test, and Dr. Alber records their test scores to assess concentration. In this study, which of the following best represents the dependent variable?
A) Type of background noise (music or silence)
B) Test scores
C) Duration of the study session
D) Number of students in each group
B. test scores
