Scribepost for January 22, 2009

Today in math we had a test on **measures of central tendency.**The test was out of 42 with questions about **mean**, **median**, **mode**, **range**, and **outlier**.**Mean**: The sum of the numbers in the data set divided by the total numbers of numbers in the data set.eg. 10,14, 20, 9. 10 + 14 + 20 + 9 = 53 ------> 53 / 4= 13.25 ------> 13.25=mean**Median**: The number in the middle of the data set.eg. 8, 11, 14, 17, 23. / The middle in the data set is 14.**Mode**: The number that appears most in a data set.eg. 12, 9, 5, 9, 9, 15. The mode is 9.**Range**: The number you get when you get the highest number and the lowest number in the data set then subtract the highest number by the lowest number in the data set.eg. 5, 10 , 15, 20. --------> 20 - 5 = 15 ----------> The range is 15.**Outlier**: The number that is greatly lower or greatly higher than the other numbers in the data set.eg. 14, 13, 79, 17, 21. The outlier is 79.After you are done your test you were supposed to do your number of the day.Today's number was 3179.269** ****remember number of the day is homework everyday**.If you finished your number of the day you were supposed to do a math problem.If you did not finish this during class time it is homework.I choose Ezekiel for the next scribe.
