58

archival research

method of research using past records or data sets to answer various research questions, or to search for interesting patterns or relationships

New cards
59

attrition

reduction in number of research participants as some drop out of the study over time

New cards
60

cause-and-effect relationship

changes in one variable cause the changes in the other variable; can be

determined only through an experimental research design

New cards
61

clinical or case study

observational research study focusing on one or a few people

New cards
62

confirmation bias

tendency to ignore evidence that disproves ideas or beliefs

New cards
63

confounding variable

unanticipated outside factor that affects both variables of interest, often giving the false impression that changes in one variable causes changes in the other variable, when, in actuality, the outside factor causes changes in both variables

New cards
64

control group

serves as a basis for comparison and controls for chance factors that might influence the results of the study—by holding such factors constant across groups so that the experimental manipulation is the only difference between groups

New cards
65

correlation coefficient

number from -1 to +1, indicating the strength and direction of the relationship between variables, and usually represented by "r"

New cards
66

becomes smaller;

New cards
91

when observations may be skewed to align with observer expectations
