Question 1
Determine whether the given value is a statistic or a parameter.
A survey found that 96% of all respondents were optimistic.
The value is a statistic because it is a numerical measurement describing
some characteristic of a population.
The value is a parameter because it is a numerical measurement describing
some characteristic of a population.
The value is a parameter because it is a numerical measurement describing
some characteristic of a sample.
The value is a statistic because it is a numerical measurement describing
some characteristic of a sample.

A discrete data set because there are a finite number of possible values..
The value is from a continuous data set because there are infinitely many
possible values and those values cannot be counted.
The data set is neither continuous nor discrete.
The value is from a continuous data set because the number of possible
values is infinite and countable.

Determine which of the four levels of measurement ( nominal, ordinal,
interval, ratio) is most appropriate for the data below.
Volumes of brain in cubic centimeters.
The ordinal level of measurement is most appropriate because the data can
be ordered, but differrences cannot be found or are meaningless.
The ratio level of measurement is most appropriate because the data can be
ordered, differrences ( obtain by subtraction) can be found and are
meaningful, and there is a natural starting point.
The interval level of measurement is most appropriate because the data can
be ordered, differrences ( obtain by subtraction) can be found and are
meaningful, and there is no natural starting point.
The nominal level of measurement is most appropriate because the data
cannot be ordered.

Question 5
Determine which of the four levels of measurement ( nominal, ordinal,
interval, ratio) is most appropriate for the data below.
Ranks of cars evaluated by a consumer's magazine.
The nominal level of measurement is most appropriate because the data
cannot be ordered.
