Identify the level of measurement of the data set. Explain your reasoning.

What is the data set's level of measurement? Explain your reasoning.
A.Ratio. The data can be ordered and differences between data entries are meaningful, and the zero entry is an inherent zero.
B.Nominal. the data caterorized using names labels or qualities but the data cannot be ranked or arranged in order
C.Interval. The data can be ordered and differences between data entries are meaningful, but the zero entry is not an inherent zero.
D.Ordinal. The data can be arranged in order, but the differences between data entries are not meaningful.

2)Identify the sampling techniques used, and discuss potential sources of bias (if any). Explain. Assume the population of interest is the student body at a university.
Questioning students as they leave an athletic facility, a researcher asks 350 students about their drinking habits.

What type of sampling is used?

.
A. Simple random sampling is used, because students are chosen at random.
B.Convenience sampling is used, because students are chosen due to convenience of location.
C.Cluster sampling is used, because students are divided into groups, groups are chosen at random, and every student in one of those groups is sampled.
D.Stratified sampling is used, because students are divided into groups, and students are chosen at random from these groups.
E.Systematic sampling is used, because students are selected from a list, with a fixed interval between students on the list.

What potential sources of bias are present, if any? Select all that apply.

A.The sample only consists of members of the population that are easy to get. These members may not be representative of the population.
B.University students may not be representative of all people in their age group.
C.Because of the personal nature of the question, students may not answer honestly.
D.There are no potential sources of bias.

Does the mean represent the center of the data?

.
A. The mean represents the center.
B. The mean does not represent the center because it is not a data value.
C.The mean does not represent the center because it is the largest data value.
D.The mean does not represent the center because it is the smallest data value.
E.The data set does not have a mean.

Find the median. Select the correct choice below and, if necessary, fill in the answer box to complete your choice.
A.The median is
(Type an integer or decimal rounded to one decimal place as needed.)
B. The data set does not have a median.

Does the median represent the center of the data?
A. The median represents the center.
B.The median does not represent the center because it is the smallest data value.
C.The median does not represent the center because it is the largest data value.
D. The median does not represent the center because it is not a data value.
E.The data set does not have a median.

Find the mode. Select the correct choice below and, if necessary, fill in the answer box to complete your choice.
A.The mode(s) is/are
(Type an integer or decimal rounded to one decimal place as needed. Use a comma to separate answers as needed.)
B.The data set does not have a mode.

Does (Do) the mode(s) represent the center of the data?
A. The mode(s) represent(s) the center.
B.The mode(s) does (do) not represent the center because it (they) is (are) not a data value.
C.The data set does not have a mode.
D.The mode(s) does (do) not represent the center because it (one) is the largest data value.
E.The mode(s) does (do) not represent the center because it (one) is the smallest
