Purpose of Data Analysis, understanding the data

1.     Understanding the Data
v What  are  variables?
v What  are  the  constants?                
v (Chances  of constants are very less but there can be; variables are required
v actually)
2.     To Determine the Level of Measurement
v What level is there; nominal/ordinal/interval or ratio.
3.     To Try to Find out Variables of Interest

4.     Distributions

types of kurtosis, leptokurtic, mesokurtic, platykurtic

 KURTOSIS PEAKEDNESS OF A DISTRIBUTION LEPTOKURTIC:  high and thin MESOKURTIC:  normal in shape PLATYKURTIC:  flat and spread out   •   KURTOSIS measures how peaked the histogram is •   The KURTOSIS of a NORMAL DISTRIBUTION is 0 •   KURTOSIS characterizes the relative PEAKEDNESS or FLATNESS of a distribution compared to the normal distribution.  PLATYKURTIC When the kurtosis < 0, the frequencies throughout the curve are closer to be equal (i.e., the curve is more flat and wide). Thus, negative kurtosis indicates a relatively flat distribution. LEPTOKURTIC When the kurtosis > 0, there are high frequencies in only a small part of the curve (i.e, the curve is more peaked). Thus, positive kurtosis indicates a relatively peaked distribution  •   KURTOSIS is based on the size of a distribution's tails. •   NEGATIVE kurtosis (PLATYKURTIC) - distributions with short tails •   POSITIVE kurtosis (LEPTOKURTIC)...
