27
t statistic
inferential statistical test to determine whether a statistically significant difference between 2 groups exists
28
correlated t test
a variation of the t test used when there is only one group or when groups are related; (also called "paired t test")
29
independent t test
a variation of the t test used when data values vary independently from one another
30
analysis of variance (ANOVA)
inferential statistical test used when the level of measurement is interval or ratio and more than two groups are being compared

networking
interacting with colleagues to exchange information and build relationships

type of content typically included in EBP posters
PICO question
43
notices are also called
calls for abstracts
44
what is a barrier to dissemination?
reliance on traditional methods such as posters, papers, and presentations
45
T/F: A major advantage of poster presentations over other methods is that opportunities for networking exist
true
46
the cycle of scientific development is an important phase in:
dissemination
47
T/F: evidence-based practice cannot be successful if nurses fail to read or hear about new knowledge
true
48
T/F: from any library websites, we can easily accessible electronic journals.
false: most libraries fall short of providing an effective platform for electronic journals
49
hypothesis testing
collection of objectively measurable data that are gathered through the five senses to confirm or refute a hypothesis; empirical testing; a test for construct validity
50
convergent testing
a test for construct validity in which new instruments are administered at the same time as an instrument known to be valid; scores of the two instruments are compared, and strong, positive correlations indicate good validity
51
divergent testing
test for construct validity in which new instruments are administered at the same time as an instrument measuring the opposite of the concept; scores of the two instruments are compared, and strong negative correlations indicate good validity
52
parametric
inferential statistical test involving interval- or ratio- level data to make inferences about the population
53
nonparametric
inferential statistics involving nominal- or ordinal- level data to make inferences about the population
