Name ___________________________________________
SHORT ANSWER. Using the following information, write the word, phrase, or
value that best answers the problem.
Determine whether the given value is a statistic or a parameter.
1) In studying the Loggerhead turtle on Anna Maria Island, FL, scientists observe the
average (mean) number of hatchlings in all 253 nests.
2) A sample of Medtronic's rechargeable implanted spine stimulator batteries lasted an
average (mean) of nine years.
Determine whether the given values are from a discrete or a continuous data set.
3) A sample of Dall sheep is measured to have an average (mean) horn length of 35.7
inches.
4) The number of hatchlings from a sample of 45 bluebird nests is 135.
MULTIPLE CHOICE. Select the choice that best answers the problem.
Determine which of the four levels of measurement is most appropriate.
5) Doctors measure the weights (in pounds) of preterm babies. What type of data is
collected?
A) Nominal
B) Ordinal
C) Interval
D) Ratio
6) Ornithologists classify hummingbirds in the United States using 17 different
species: Allen, Anna, Berylline, Black-chinned, Blue-throated, Broad-billed, Broad-
tailed, Buff-bellied, Calliope, Costa, Lucifer, Magnificent, Ruby-throated, Rufous,
Violet-crowned, White-eared, and Xantus. What type of data is collected?
A) Nominal
B) Ordinal
C) Interval
D) Ratio
7) The income range of attendees at a research conference is gathered as upper, middle,
and low levels. What type of data is collected?
A) Nominal

Hampshire. What type of data is collected?
A) Nominal
B) Ordinal
C) Interval
D) Ratio
SHORT ANSWER. Using the following information, write the word, phrase, or
value that best answers the problem.
Identify (a) the sample and (b) the population.
9) A graduate student conducts a research study on undergraduate student smoking
habits. She begins with a survey to 500 randomly selected undergraduate students
from 10 randomly selected U.S. universities.
10) A researcher randomly selects 50 one-square meter locations at the Anna-Borrego
Desert State Park in California to determine the survival rate of Desert poppies and
Arizona lupines.
Determine whether the given description corresponds to an observational study or
an experiment.
11) In a study of cold symptoms, the body temperatures of study participants were
taken.
12) Children with attention deficit hyperactivity disorder are randomly divided into four
treatment groups (the Tomatis Method, the Dore Method, the Brain Gym, and a
control group) to compare differences in focus and concentration.
Identify the type of observational study: cross-sectional, retrospective, or
prospective.
13) A researcher from the department of defense is studying the psychology of trauma.
He plans to follow the children of service members who died in Afghanistan for the
next 20 years.
14) Scientists studying the migration habits of Aleutian geese collect data from reports
measuring the number of geese during "fly-offs" over the past 15 years.
Determine the type of sampling used: systematic, convenience, stratified, or
cluster.
15) A county water quality control officer obtains a list of all residential addresses in the
county and constructs a sample of homes to monitor by selecting every 200th home
on the list.
16) To conduct a study of Johnson & Johnson shareholder attitudes, a list of shareholder
zipcodes is compiled. All shareholders from 20 different zipcodes are selected to be
surveyed.
