experimental design
no manipulation of the IV, no random selection/assignment - CORRECT ANSWER✅✅nonexperimental
design
Most common research design in nursing studies? - CORRECT ANSWER✅✅nonexperimental
Types of non experimental designs? - CORRECT ANSWER✅✅descriptive
correlational(cross-long)(retro/pro)
Four types of correlational non experimental designs? - CORRECT ANSWER✅✅retrospective
prospective
cross sectional
longitudal
the process of selecting individuals for a study - CORRECT ANSWER✅✅sampling
,subset of a population - CORRECT ANSWER✅✅sample
type of sampling in which every subject in a population has an equal chance of being chosen - CORRECT
ANSWER✅✅probability sampling
Different types of probability sampling? - CORRECT ANSWER✅✅simple random
systemic
cluster
stratified
A type of probability sampling in which the population is divided into subsections and a simple random
sample is taken - CORRECT ANSWER✅✅stratified random sampling
A type of probability sampling in which every kth is selected into sample - CORRECT
ANSWER✅✅systemic sampling
Type of probability sampling in which the researcher selects groups or subjects rather than an individual
- CORRECT ANSWER✅✅cluster sampling
probability sampling where every subject has an equal and independant chance of being chosen -
CORRECT ANSWER✅✅simple random sampling
Type of sampling in which the sample is not selected using random assignment, chance plays no role in
this determination of sample - CORRECT ANSWER✅✅non probability sampling
Types of non probability sampling - CORRECT ANSWER✅✅convenience, quota, purposive, snowball,
network
type of non probability sampling in which the researcher selects subjects readily available - CORRECT
ANSWER✅✅convenience sampling
, type of non probability sampling where quotas are filled - CORRECT ANSWER✅✅quota sampling
type of non probability sampling in which the researcher selects only subjects that satisfy the prescribed
characteristics - CORRECT ANSWER✅✅purposive sampling
type of non probability sampling that relies on subjects identifying other subjects with similar
characteristics - CORRECT ANSWER✅✅snowball sampling
type of non probability sampling where researchers ask subjects to help get in touch with other subjects
through social networks - CORRECT ANSWER✅✅network sampling
pros and cons to convenience sampling - CORRECT ANSWER✅✅pros-easy, cheap
cons-potential for bias, limited ability to generalize research
Three attributes to evidence: - CORRECT ANSWER✅✅replicability-findings are verified in other studies
reliability-findings are consistent
validity-accuracy of findings and application
protection, promotion and optimization of health - CORRECT ANSWER✅✅nursing
they read, interpret and evaluate research for practice - CORRECT ANSWER✅✅research consumer
a testimony of facts tending to confirm or disprove any conclusions or something that furnishes
verification - CORRECT ANSWER✅✅evidence
use of evidence to guide practice while incorporating key elements of patient involvement and the
expertise of nurses - CORRECT ANSWER✅✅evidence based practice
