type I error
type of error that occurs when the researcher rejects a null hypothesis that
is actually true; more serious than type II
type II error
type of error that occurs when the researcher accepts a null hypothesis that
is actually false; often occurs when the sample is too small
risk
what chance are you willing to take that you will make a type I error?
power
the probability that a statistical test will detect an effect/difference
when it actually exists; can address the number of participants
needed for a study
,80% (0.80)
what value is adequate for the probability of obtaining a significant
result regarding power?
sensitivity
the proportion of those with disease who test positive; a measure of how
well
the test detects disease when it is really there; probability of having the
disease (true positive rate)
specificity
the proportion of those without disease who test negative; measures how
well
the test rules out disease when it is really absent; probability of the absence
of disease (true negative rate)
likelihood ratio
can help researchers to determine the accuracy of diagnostic or
screening tests, which are based on the sensitivity and specific results
-large negative = high degree of certainty that the patient does not have the
disease
-large positive = high degree of certainty that the patient does have the
disease
what does a large negative and positive likelihood ratio indicate?
,quantitative
type of nursing research that uses statistical tests; is very
structured/scientific way of measuring and analyzing
qualitative
type of nursing research that seeks to understand the meaning of human
experience
people's natural settings
where is qualitative data usually conducted?
in a lab or controlled setting
where is quantitative data usually conducted?
-qualitative = subjectivity
-quantitative = objectivity
what is important to maintain in qualitative research? quantitative
research?
-qualitative = theory generating
-quantitative = theory testing
what is true of theory in qualitative vs quantitative nursing research?
, specific populations, units, or facilities
what is quality improvement used for (what settings)?
1. conduct an assessment
2. set specific goals for improvement
3. identify ideas for changing current practice
4. decide how improvements in care will be measured
5. rapidly test practice changes
6. measure improvements in care
7. adopt the practice change as new standard of care
what are the steps of quality improvement?
must have research
what MUST you have in order to have evidence-based practice?
-research
-clinical expertise
-patient and family values
what are the components of EBP?
