NURS 405 test | 2026 Update Questions with
complete solutions.
quantitative
_____ researchers measure and count phenomena, then analyze the numbers to portray and
determine their relationship with other phenomena
qualitative
_____ researchers seek to understand the meaning of human experiences and social interaction
causality
the relationship that exists between a cause and its effect
probability
the likelihood or chance that an event will occur in a situation
probability
how likely was the change in the dependent variable caused by the independent variable
extraneous/confounding variables
factors that distort or interfere with the relationship between independent variable and dependent
variable
bias
can occur when extraneous variables influence and/or distort the relationship between the
independent variable and dependent variable
, bias
systematic error in selection of participants, measurement of variables, and/or analysis of data
that distorts the true relationship between IV and DV
Describing a phenomenon in detail (nonexperimental)
Explaining relationships and/or differences among variables (nonexperimental)
Predicting relationships and/or differences among variables (nonexperimental)
Examining causality (experimental)
quantitative designs can be used for four key purposes:
the role of the researcher: in nonexperimental designs, there is the lack of researcher
manipulation. in experimental designs, the independent variable is manipulated
what is the main difference between nonexperimental and experimental designs?
experimental design
type of quantitative design: the researcher plays an active role by manipulating the independent
variable
experimental design
type of quantitative design: includes manipulation, control of variable (remove extraneous and/or
take into consideration when examining results) and randomization
A hypothesis that tests a causal relationship (i.e., testing for the effect that an IV has on a
DV)
