How to give an explanation for each of the descriptive statistics tables below?

for variabel first ; avg emp

mean is 31.70416659 : it is represent the center value of the sample data :

standard error : 3.776977876 :   the standard error of the mean estimates the variability

between samples, the standard deviation measures the variability within a single sample.

median : 26.125 : it is midpoint of the data

mode : 15.25 : most frequently observation is data

standard deviation : 29.25634482 : it is measure of the dispersion .

Sample variance : 855.9337125 : it measures how spread out the data are about their mean

Kurtosis : 4.067240519 : it indicates how the peak and tails of distribution differ from the normal distribution

Skewness : 1.830126167 : it is the extent to which the data are not symmetrical .

Range : 135: it is the difference between the largest and smallest data values in the sample.

Minimum : 0.833333333 : smallest value in the data is 0

maximum : 135.83333 : it is largest value in the data

sum : 1902 .249995 : it is addition of the all the observation

count : 60 : total observation in the data


## here mean > median > mode we can say that there is positive distribution . positive kurtosis , and positive symmetric

## for variable second ; acc per emp

mean : 0.074657099 : it is represent the center value of the sample data :

standard error : 0.008174733 :   the standard error of the mean estimates the variability

between samples, the standard deviation measures the variability within a single sample.

median : 0.071822413 : it is midpoint of the data

Range : 0.282352941 : it is the difference between the largest and smallest data values in the sample.

Minimum : 0 : smallest value in the data is 0

maximum : 0.282352941: it is largest value in the data

sum : 4.479425924 : it is addition of the all the observation

count : 60 : total observation in the data

## here mean > median > mode we can say that there is positive distribution . positive kurtosis , and positive symmetric

## for variable third  ; miles per driven

mean : 948289.6333 : it is represent the center value of the sample data :

standard error : 97683.20756 :   the standard error of the mean estimates the variability

between samples, the standard deviation measures the variability within a single sample.

median : 835350 : it is midpoint of the data

mode : NA : most frequently observation is data

standard deviation : 756650.8721 : it is measure of the dispersion .

Sample variance : 5.72521E+11 : it measures how spread out the data are about their mean

Kurtosis : 0.288442522 : it indicates how the peak and tails of distribution differ from the normal distribution

Skewness : 0.817140927 : it is the extent to which the data are not symmetrical .

Range : 3053137 : it is the difference between the largest and smallest data values in the sample.

Minimum : 11000 : smallest value in the data is 0

maximum : 3064137 : it is largest value in the data

sum : 56897378 : it is addition of the all the observation

count : 60 : total observation in the data
