On the other hand, the upper limit for every class ...A statistic is a number that represents a property of the sample. For example, if we consider one math class to be a sample of the population of all math classes, then the average number of points earned by students in that one math class at the end of the term is an example of a statistic. ….

A characteristic (usually numeric) that describes a sample is referred to as a sample statistic. NOTE: Inferential statistics are used to help the researcher infer how well statistics in a sample reflect parameters in a population. DEFINITION The formula for the Expected Value for a binomial random variable is: P (x) * X. X is the number of trials and P (x) is the probability of success. For example, if you toss a coin ten times, the probability of getting a heads in each trial is 1/2 so the expected value (the number of heads you can expect to get in 10 coin tosses) is: P (x) * X ...
