22% is a parameter since, apparently, there is no sampling here but a complete census of the math department.





From Wikipedia:


Statistics are mathematical characteristics of samples which can be used as estimates of parameters, mathematical characteristics of the populations from which the samples are drawn. For example, the sample mean () can be used as an estimate of the mean parameter (渭) of the population from which the sample was drawn.Determine whether the value is a statistic or a parameter. 22% of the teachers in the math department have mor
if this is coming from asking the teachers and finding a sample proportion then this is a statistic. if it is a value from the underlying distribution then it is a parameter.





Remember that if you are give population values then you have parameters. if you are given sample values then you have statistics.
