What are some examples of statistics? 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.

For example, when we toss a coin, either we get Head OR Tail, only two possible outcomes are possible (H, T). But when two coins are tossed then there will be four possible outcomes, i.e {(H, H), (H, T), (T, H), (T, T)}. Download this lesson as PDF: – Download PDF HereMar 18, 2017 · By using the z-score formula: z = ( x - μ) / σ we can convert any distribution to the standard normal distribution. Here the Greek letter μ the mean and σ is the standard deviation. The standard normal distribution is a special normal distribution. It has a mean of 0 and its standard deviation is equal to 1. ambler reccottage bloxburg house Number of ways it can happen: 1 (there is only 1 face with a "4" on it) Total number of outcomes: 6 (there are 6 faces altogether) So the probability = 1 6. Example: there are 5 marbles in a bag: 4 are blue, and 1 is red. Correlation means there is a relationship or pattern between the values of two variables. A scatterplot displays data about two variables as a set of points in the x y -plane and is a useful tool for determining if there is a correlation between the variables.
