Copy to Clipboard + Open in Excel +Explanation / Answer
A) Mean = (557 + 339 + 378 + 399 + 512 + 504 + 308)/6 = 499.5
Data in ascending order: 308, 339, 399, 504, 512, 557
B) median = (n+1)/2 term
= (6+1)/2 = 3.5th term
= (399 + 504)/2
= 451.5
C) Midrange = (upper value + lower value)/2
= (557 + 308)/2
= 432.5
D) B.There is no mode
