True - CORRECT ANSWER-Heart rate is measured on a ratio scale
False - CORRECT ANSWER-a 20-item scale to measure depression would yield nominal-level
measures
False - CORRECT ANSWER-Researchers use descriptive statistics to draw conclusions about
population values
False - CORRECT ANSWER-A descriptive index from a population is called a statistic
True - CORRECT ANSWER-The three characteristics that can be completely summarize a
distribution of data are the shape of the distribution, central tendency, and variability
False - CORRECT ANSWER-"Age at death" is an example of a positively skewed attribute
False - CORRECT ANSWER-The median is affected by the value of each individual score
True - CORRECT ANSWER-The standard deviation is an index that communicates how spread out
scores are in distribution
False - CORRECT ANSWER-Two sets of data with identical means would likely have the same
standard deviation
False - CORRECT ANSWER-A normal distribution is skewed when there are 3 standard deviations
above the mean
False - CORRECT ANSWER-Another name for a normal distribution is a sampling distribution
True - CORRECT ANSWER-A +.50 correlation coefficient indicates a weaker relation than does a
correlation of -.75
,False - CORRECT ANSWER-This is an example of a negative correlation: As daily sodium intake
increased, blood pressure readings got higher
False - CORRECT ANSWER-Crosstabs tables are usually constructed with variables measured on
the interval scale
True - CORRECT ANSWER-A absolute risk reduction index could be computed to compare the risk
of patient falls for patients in two different age groups
True - CORRECT ANSWER-As a standard deviation for a sample size gets smaller so does the
estimate of the standard error of the mean
True - CORRECT ANSWER-A 99% CI around a mean is wider than a 95% CI
False - CORRECT ANSWER-A Type 1 error would occur if a researcher concluded that no group
difference exists when, in fact, a difference does exist
True - CORRECT ANSWER-A researcher never knows whether an error in statistical decision
making has been committed
True - CORRECT ANSWER-A statistically significant finding means that the obtained results are
not likely to have been due to chance
True - CORRECT ANSWER-A t-test can be used to test mean differences for two independent
groups (e.g., men vs. women) for a single group at two points in time
False - CORRECT ANSWER-A researcher would test the difference between the means of three
groups of patients using a t-test
False - CORRECT ANSWER-The chi-squared statistic may be considered to be both descriptive
and inferential
True - CORRECT ANSWER-The effect size indicator that would be appropriate to summarize
effects in a t-test situation is d
False - CORRECT ANSWER-The square root of the multiple correlation coefficient R tells much
variability in the outcome variable can be explained by the independent variables
,True - CORRECT ANSWER-In multiple regression, independent variables are often called
predictor variables
True - CORRECT ANSWER-In a multiple regression, the outcome variable is measured on an
interval or ratio scale
True - CORRECT ANSWER-In logistic regression, the outcome variable is measured on the
nominal scale
True - CORRECT ANSWER-Adding covariates to an ANOVA can help to improve the study's
internal validity through statistical control of confounding variables
True - CORRECT ANSWER-In the following statement, the results are not statistically significant at
conventional levels: (r= .12, df=33, p> .05)
False - CORRECT ANSWER-When a statistical analysis yields a p < .001, there is no risk for a type 1
error
False - CORRECT ANSWER-The appropriate index for estimating a measure's test-retest reliability
is coefficient alpha
False - CORRECT ANSWER-Reliability coefficients ideally have a value of less than .80
True - CORRECT ANSWER-If a known-groups approach to assessing construct validity is used, the
statistical analysis could involve a t-test for independent groups
False - CORRECT ANSWER-Sensitivity is the ability of an instrument to correctly identify noncases
(the rate of true negatives)
False - CORRECT ANSWER-One of the features of qualitative analysis is that there are universally
accepted formal rules that facilitate the process
False - CORRECT ANSWER-Data analysis in qualitative studies cannot begin until data saturation
has been achieved
False - CORRECT ANSWER-Coding schemes are generally developed after the completion of a
thematic analysis
, True - CORRECT ANSWER-Like quantitative analysts, qualitative analysts often search for
relationships and patterns within the data
False - CORRECT ANSWER-When CAQDAS is used, the software creates the category scheme and
codes the data
False - CORRECT ANSWER-Metaphors are especially likely to be used in ethnographic research
False - CORRECT ANSWER-In Spradley's ethnographic method, the highest level of analysis is
taxonomic
True - CORRECT ANSWER-In ethnographic analyses, domains are broad units of cultural
knowledge that encompass smaller categories
False - CORRECT ANSWER-The Duquesne and Utrecht schools of phenomenology developed
methods of analyzing phenomenological data that are essentially the same
True - CORRECT ANSWER-In Benner's hemeneutical approach, paradigm cases are strong
instances of being in the world with regard to a phenomenon of interest
False - CORRECT ANSWER-Both grounded theory and phenomenological analysis focus on a
search for themes
False - CORRECT ANSWER-The original term of grounded theory researchers included Glaser and
Corbin
False - CORRECT ANSWER-Axial coding is a term associated with the constructivist approach to
grounded theory analysis
True - CORRECT ANSWER-In Glaserian grounded theory, the higher the level of coding, the
greater the level of abstraction
True - CORRECT ANSWER-A BSP is a core category, but not all core categories are BSPs
research purpose - CORRECT ANSWER-A clear, concise statement of the specific focus on or aim
of a study, identifyingthe reason the study was conducted.
research purpose - CORRECT ANSWER-A short statement, frequently single a single sentence
