MEAN
  • arrange the data in ascending order
  • add the data up
  • divide the data's sum by the number of data in the data
  • with an outlier in the data the mean is not that accurate
  • arrange the data in ascending order
  • the middle number in the data is the median(find the middle number)
  • if there are two medians add them up and divided by two
  • when data has an outlier the median would be the best choice

MODE

  • arrange the data in ascending order
  • the most frequently used number is the mode
  • there can be more that one mode
  • there can be no mode
RANGE
  • arrange the data in ascending order
  • subtract the smallest data from the largest data
  • LARGE data = outlier
