Yes or no?Data Set 2: Data Set 2 Answer: yes What’s the middle number then? 25 and/or 30 Finding median for even number set Add the two middle numbers Then divide by twoData Set 2: Data Set 2 Median Add 25 and 30 Total = 55 55 ÷ 2 Answer= 27.5 Half the numbers are less than Half the numbers are greaterData Set 2: Data Set 2 Mode = 40 Can there be two modes Answer: yes, called bimodal Example: (4,4,6,6) Both 4 and 6 appear twice Mode = 4, 6Final Example: Final Example Find the mean, median, mode for… 100,100,165,215,240,240 Mean = 176.66666… Median = 190 Mode = 100, 240Key Thoughts to Remember: Key Thoughts to Remember Mean is the average Median is the middle number Mode is the number appearing most You do not have the permission to view this presentation.
