Mean  :  X^2 found the mean to  be   : Sum of the data  / 24 =  5262 / 24  = 219.25

 

Median ...order the data from  low to high

 

138,152, 164, 172, 176, 182, 186, 186, 190, 190,  207, 213, 216, 233, 236, 240, 242, 259, 268, 274, 274, 285, 288, 291

 

We have 24 values...the median will come from the average of the 12th and 13th terms =  [ 213 + 216 ] / 2 = 214.5

 

 

The mode is/are the value(s) that appear(s) most often  = 186, 190 and 274  [ this data  is "tri-modal" ]

 

The range is  just the greatest weight  - the lightest weight =  291 - 138  = 153
