ASYMMETRY AND POINTINGMEASURES

ASYMMETRY AND POINTINGMEASURES

1. are part of

   • UNIVARIATE STATISTICAL MEASURES

2. They measure data distribution with formulas, without having to make their graphical representation

3. ASYMMETRY

   • to calculate is used
     • FISHER COEFFICIENT
     • PEARSON COEFFICIENT
   • IDENTIFY HOW THE DATA ARE DISTRIBUTED AROUND THE ARITHMETIC MEAN
     • NEGATIVE ASYMMETRY CURVE
     • SIMEMETRY CURVE
     • POSITIVE ASIMMETRY CURVE

4. KURTOSIS

   • IDENTIFY HOW THE DATA IS CONCENTRATED AROUND THE ARITHMETIC MEAN
     • LEPTOKURTIC (excess kurtosis > 0)
     • MESOKURTIC (excess kurtosis = 0)
     • PLATYKURTIC (excess kurtosis < 0)
   • to calculate is used
     • KURTOSIS COEFFICIENT
