This post will share key information, formulas, and vocabulary so that you can use math to determine the mean, median, mode, and range of any data set and understand what these values represent. after working through two examples, you will also have access to a free mean, median, and mode pdf practice worksheet that includes an answer key. Step 1) put the data into an ordered list. this gives us: 9, 12, 14, 15, 21, 27, 30, 32. step 2) check the number of data points in both lists is the same. both lists have 8 data points. step 3) the range is the difference or gap between the largest and smallest numbers. answer: the range is 32 9=23.
Correct answer: mean. explanation: put the data in order from smallest to largest and then calculate each stastic: mean, mode, median, range. 2, 3, 5, 7, 9, 9, 10, 12, 15. range = max − min or 15 − 2 = 13. mode is the most often repeated number or 9. median is the number in the middle or 9. mean is the sum of the data divided by the number. Measures of central tendency do not provide information about the individual values of a data set. rather, it is a set of numerical values that best represent or summarize the middle of the data. The "median" is the "middle" value in the list of numbers. to find the median, your numbers have to be listed in numerical order from smallest to largest, so you may have to rewrite your list before you can find the median. the "mode" is the value that occurs most often. if no number in the list is repeated, then there is no mode for the list. Mean, median, mode & range mean example 1. all right this is a cool trick; this is called the average pie, and the average pie is when you have three pieces of information, or you need the third.

Find the minimum value (smallest number) in your dataset. step 3. subtract the minimum value from the maximum value. for example, if your dataset is. 2, 5, 8, 3, 10. the range would be 10 (maximum) − 2 (minimum) = 8. in general, the bigger the value of the range, the more “spread out” the data is. range example 1.
