Consider three data series, each a random sample of seven observations (n = 7):
Series 1: { 1 , 1 , 1 , 3 , 5 , 5 , 5 }
Series 2: { 1 , 1 , 3 , 3 , 3 , 5 , 5 }
Series 3: {1, 3, 3, 3, 3, 3, 5}
Series 1 is:
A.platykurtic
B.mesokurtic
C. heterokurtic
D. leptokurtic
Correct Option: A. platykurtic
It is because the kurtosis of series A is -2.6 and negaitve kurtosis is known as platykurtic.
