Because of this, the median of the list will be the mean (that is, the usual average) of the middle two values within the list. The middle two numbers are 2 and 4, so: (2 + 4) ÷ 2 = 6 ÷ 2 = 3. So the median of this list is 3, a value that isn't in the list at all.

Examples on Inferential Statistics. Example 1: After a new sales training is given to employees the average sale goes up to $150 (a sample of 25 employees was examined) with a standard deviation of $12. Before the training, the average sale was $100. Check if the training helped at α α = 0.05.

Elementary Statistics 1: Sampling and Data 2: Graphical Representations of Data 3: Descriptive StatisticsEssentially, parameters are unknown and the main game of statistics is to try to estimate parameters on the basis of small samples collected from the population. Definition 3. A quantitative measure of a sample data is called a statistic. So, any constant that we compute from a sample is a statistic.Example: there are 5 marbles in a bag: 4 are blue, and 1 is red. What is the probability that a blue marble gets picked? Number of ways it can happen: 4 (there are 4 blues). Total number of outcomes: 5 (there are 5 marbles in total). So the probability = 4 5 = 0.8Statistics has gotten a reputation for being a very hard class, especially when taken in college, because it combines math concepts in order to form an analysis of a data set that can be used to understand an association in the data (whoo that was a mouthful).
