Question

Determine whether the value given is a parameter or statistic. Two thirds of all the students in this class are womena. Parameterb. Statistic

Answer 1

Parameter

Explanation:

The given value is Parameter because it contains the measurement of population. In short, the given value 2/3 is the estimated value of population.

The population consists of all the students in the class. If the ratio of women from all the students in the class is calculated, then it is a measure of population. Thus, the given value is parameter.

Answer 2

Answer: a. Parameter

Explanation:

Parameter can be defined as a fact/characteristic about a whole population.

For example:

i. 20% of my class are boys

ii. 40% of Canadian senators are women.

Parameter usually deal with a small measurable population.

While statistic is a characteristic/fact about the sample.

Therefore the case above is a parameter because the students in the class is the population and the stated (Two thirds of all the students in this class are women) is a fact about the population.
