Which formulas are correct (multiple choice)
Range = Highest observation - Lowest observation
mode = High frequency
Find mean, mode, median and range:
20, 16, 22, 17, 20, 10, 13, 21, 27, 14
mean = 18, mode = 20, median = 17, range = 17
mean = 20, mode = 27, median = 17, range = 21
mean = 18, mode = 20, median = 20, range = 17
mean = 20, mode = 27, median = 20, range = 21
