Directions: Determine whether the numerical value is a parameter or a statistic. Explain your answer. 1. Sixty-two of the 97 passengers aboard the Agila airship survived its explosion. 2. In a survey of 300 computer users, 8% said their computers had malfunctions that needed to be repaired by service technicians. 3. A survey of 1004 Filipino adults found that 52% think that China's emergence as a world power is a major threat to the well-being of the Philippines. 4. In January 2013, 60% of the governors of the Philippines were male.

A parameteris a value that describes some aspect of a population. A parameter
may be very difficult to determine if not impossible, especially in a large population. This
is where samples and statistics come into play.
However, a parameter can be determined in a very small population where every
individual can be located with absolute certainty, for instance in a totally captive
population. In this case you can calculate a parameter directly if all individuals can be
located and measured without missing a single individual.
A statistic is a value that is an estimate of a parameter. A statistic is based on
a sample. It is calculated from a sample taken from a population.
Sampling is a way to collect information or data about a population without
actually counting or measuring every individual in the population. Sampling is often
necessary since it is often impossible to measure or count every individual within a
population since populations are often large and it may be hard to find every individual.
