False
What type of graphic display would be the best for a variable
measured at the ordinal data?
Histogram
The operational definition of a variable
Specifies how a variable should be measured
The epidemiological range is
the minimum and maximum values

should be reported?
The standard deviation
clinical data conducted can be shared to a cloud for all involved
researchers to share/view
false
The dependent variable
the outcome variable
Outliers can be identified using a (SELECT ALL THAT APPLY)
a. Box-and-whisker plot with Tukey Fences.

The decision to use the mean or median is based upon (Select all that
apply)

A. Whether the data are normally distributed
B. The presence or absence of outliers
When a continuous variable has a normal distribution and only 1
small outlier, the mean and standard deviation should be used to
describe the variable

A conceptual definition defines how a variable will be measured, and
includes the equipment and procedures that are used in the
measurement
False
Testing a new piece of equipment to ensure that the equipment
consistently provides that same measurement when the same
variable is measured multiple times is an example of
Accuracy
Validity
Reliability
All of the above
Reliability
Bar charts and histograms can both be used to describe interval level
data
False
All studies need appropriate permission to examine data
