January 25, 2013 1) Come-in check your homework using a different colored pen or pencil. 2) Put stars by any problems you have questions about. Question to think about? How do you think the vocabulary term central tendency relates to mean, median and mode?

Statistics are analyzed. Mean Median Mode

Statistics are collected. Population The set of individuals, items, or data from which a statistical example is taken Data factual information, especially information used to reason or make decisions. Two types of data: Categorical and Numerical

Two Types of Data Categorical Numerical specific labels or names for categories “how many” of each category is in the data set Ex: Restaurant Owner: Data is categorical because the owner is concerned about, which menu items are most popular. Numerical data that is counted or measured Ex: Different students’ heights

Statistics need to be OrGaNiZeD. Range Outliers Cluster The points the farthest away from other values in a set of data. Examples? The difference between the minimum and maximum values/data points. A group of the same or similar data occurring close together; a bunch

Statistics need to be OrGaNiZeD. Gaps areas where values are not present or are missing in the data set.
