3. Some in the equation that carried in the comparison is a
parameter. It can be a different thing in it. It is the opposite of
the statistic. For example, it tells about the population like a
small part of the people. It is not variable because it is seen to
decide the parameter. e.g., If you and your classmates have
some money and you ask to all and take an average of it. It will
be a parameter. But if you ask your whole school students and
make the data and use this information to guess the average
money, then it is a statistic. But your guess is correct or not
although probably near.
