What is the characteristics of mean, median, mode, and range

Mean is the average (arithmetic) of a set of numbers. It helps find the "center" when you have a lot of numbers that center around one point/number.

Median is the middle number. It helps when you have outliers.

Mode is the most frequent number. It helps when there are a lot of numbers spread out overall.

Range is the difference between the smallest and biggest number. It's just used.

a function could be identified in 3 ways either on a chart,graph, or ordered pairs. first a function is that each point has its own. the rule is that there can be many x's to one y but there can not be 2 x's at different y's. so on a graph when you put a straight line through the y's there should be one dot only to be a function.
