[Beginner] How to find the range, median, mean and mode

Post by Hiukuss on Wed Jan 11, 2012 3:20 pm

mean = add numbers for total, divide results by total number of numbers
median = middle number(s)
mode = most occurring number
range = highest number - lowest number


*two most occurring numbers: 11, 11, 12, 12 = no mode
==============================================================================

16, 22, 14, 12, 20, 19, 14, 11 is what numbers we have
11, 12, 14, 14, 16, 19, 20, 22 is after we put them in order

so...
mean = 128 / 8 = 16
median = 15
mode = 14
range = 11
==============================================================================

$135,000, $141,000, $138,000, $154,000, $131,000 is what numbers we have
$131,000, $135,000, $138,000, $141,000, $154,000 is what numbers we have after they have been put in order

mean = $699,000
median = $138,000
mode = none (no repeating number)
range = $154,000 - $131,000 = 23,000
==============================================================================

(Do correct me if I am wrong)
