Quantitative measures can be Discrete and continuous data
Three elements of control that Randomization, Manipulation, and Comparison/Control

A researcher records the time it Sample statistic
takes to complete a memory

participants. He finds that the
average participant completed
the test in 43 seconds. The
average time to complete this
task is called a(n)

A researcher identifies college The small group of college students who were observed
students as a group of interest
to test her hypothesis. She then
identifies a few local college
students and selects a small
group of the local college
students to be observed. In this
example, the sample is
Each of the following are Marital satisfaction ratings on a 5-point rating scale
interval scale measurements,
except:
-Duration of sleep (in hours)
-Marital satisfaction of ratings on
a 5-point rating scale
-The latitude and longitude of
birth for those suffering from
schizophrenia
-The body temperature (in
degrees Fahrenheit) increase
during exercise
State the four scales of Nominal, Ordinal, Interval, Ratio
measurement in order from least
informative to most informative
