Statistics is the study of analysing data, particularly large quantities of data. By analysing data statisticians hope to be able to draw conclusions or make predictions. High school math students can use these statistics problems for study purposes.

Statistics 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). Some of the individual concepts included in statistics are difficult but statistics ...

Finding the probability of a simple event happening is fairly straightforward: add the probabilities together. For example, if you have a 10% chance of winning $10 and a 25% chance of winning $20 then your overall odds of winning something is 10% + 25% = 35%. This only works for mutually exclusive events (events that cannot happen at the same ... Math Forum/Help; Problem Solver; Practice; Worksheets; Tests; Algebra; Geometry; College Math; ...

Example: The mean of 4 , 1 , and 7 is ( 4 + 1 + 7) / 3 = 12 / 3 = 4 . Median: The middle number; found by ordering all data points and picking out the one in the middle (or if there are two middle numbers, taking the mean of those two numbers).Statistics.
