Christian's Measure of Central Tendency
mean



  • put raw data into ascending order.

  • sum of all data, devided by the number of data


  • if you have an outlier it changes the mean




median



  • put raw data into ascending order

  • find the middle number

  • its the best way to find the average of the data if there is an outlier

  • if you have two middle number you have to add the two middle number and devide it by 2





mode



  • put raw data into ascending order


  • find the most occuring number in the data

  • you can have more than one mode


  • you can have no mode at all




range



  • put raw data into ascending order

  • largest data minus the smallest data


  • if there is a large range check if the mean is the best way to find the average




Here is a great video representing mean,median and mode.

hi christian! good job! but you spelled "divide" wrong, and for all your links, you attached games. your suppose to attach sites that explain the heading, and they all have to be different. if you still dont understand, just ask mr.h okay. but other than that good job!
