Descriptive Statistics in EViews and its interpretation

Hello Friends,
In today's lecture,  we will go and find Descriptive statistics by e-views. now a question arises why would we require descriptive statistics.here are a few reasons.

  1. It enables us to present the data in a more meaningful way, which allows a simpler interpretation of the data
  2. The main purpose of descriptive statistics is to provide a brief summary of the samples and the measures done on a particular study.
now open e-views and import data from the excel sheet. so finally you would be here.
then open the complete data table by pressing enter key (after selecting variables) 
now select Views from the menu bar
from view we have to select the "Descriptive Stats" option and then "Common Sample" and here we have the result window and it would be like that.
-------------------------------------------------------------------------------------------------------------------------- Interpretation of Descriptive Stats
Suppose ve have Results like that. then 
Description
GDP
Inflation
Population
Price
Mean
 4.005952
 5.410366
 3358333.
 176.2366
Median
 4.232143
 5.805868
 3358333.
 176.2366
Maximum
 5.200000
 8.440000
 5503333.
 340.6911
Minimum
 1.800000
 1.200000
 1200000.
 10.00000
Stad. Deviation
 0.829710
 2.070294
 1285960.
 98.75186
Variance
0.672400
4.286117
----
9751.5625
Skewness
-1.007070
-0.441171
-9.12E-05
-0.012148
Kurtosis
 3.144214
 2.104262
 1.798769
 1.818367

here we have mean of GDP, Inflation, Population, and Prices which explains the average of the data. Whereas Median explains the central value of the data. Maximum and minimum value expresses the range 0f data. Now moving towards the standard deviation we got how much data deviate from its central point. In our data, we can see that skewness is normal and positive for every four variables. When we talked about Kurtosis  it must be below 3. GDP has 3.14>3 so we can say that GDP is positively skewed with slight leptokurtic shape. Reaming variables (Inflation, Population, and Price) are less than 3 Kurtosis as well as positively skewed and have Masokartic shape.
