Mean, Median, and Mode 13R 13L 09/22/11 Mean, Median, and Mode Reflection 09/22/11 Observe, Question, Comment Warm-Up: Standard: Objective:

 To find the mean, median, mode and range of a set of data

Mean, Median, and Mode 13R 13L 09/22/11 Mean, Median, and Mode Reflection 09/22/11 Observe, Question, Comment Warm-Up: Standard: Objective: Vocabulary:

The sum of the data values divided by the number of data values

The middle number when data values are written in order

The data item that occurs most often. There can be one mode, more than one, or no mode.

The difference between the greatest and least values

 Create a Data Set that will have the mean, median and mode to be the same answer  Meaning This: ◦ Mean = Median = Mode

 Mean → the average  Median → the middle  Mode → the most  Range → big minus small

Vocabulary (Shout Outs)  Bar Graph → bars to show comparison  Frequency Table → list each item  Histogram → bar graph with no spaces
