Determine whether the number described is a statistic or a parameter. According to a sample of college students, the average amount of sleep they get each night is 6.2 hours. is this number a Parameter or Statistic ?

Statistic.

Explanation: The average amount of sleep gotten each night by student described in the scenario above is a statistic. This is because the average sleep time of 6.2 hours represents a statistical value obtained from only a sample of the entire population of college students. Hence, statistical figures obtained from a fraction of the entire population which is meant to be representative of the total population is called statistic. If the statistical figure obtained is derived by taking into account all members of the population, then it is called parameter.
