### Statistics of Love

Three boys saw an extremely beautiful girl . After seen the girl the boys were not able to stop themselves to propose the girl. So, the boys  approached the girl and after came to her  they  said,” Excuse us Miss, we would like to say something to  you.”

The girl looked the boys very gently and replied, “ Please, gentlemen if you have any problem?.”

One of them said in a very soft and calm voice, “ Miss , we want to say that after having  seen you , we have some sweet –sweet feeling in our  heart for you, we think all of  us are in Love with you. Will u marry one of us?.”
Now the girl who belongs to statistical background said, “ok, gentlemen it feels very nice to heard all these, but one thing I would like to say  that can you prove it statistically? I would like to choose the best among you.”
Now the Lips of all three boys were  sealed and  they  thought that how could it be possible to prove the love statistically.
They  got back to their position and continuously thinking about this through the whole day but never forget the face of the girl.
In search of solution they went to a professor of statistics and told him about their problem.
The professor advised them, “Ask the girl to allow you to see her continuously for ten days”.
Next day on the same place , They go to the girl and asked her the same thing.
The girl replied to the boys , “she has no problem on this but they  will not try to misbehave with her at any cost”
The boys had given promise on this.
Now the boys  went to the professor and tell him that the girl allowed them  to see her for ten days .
Now professor advised them,“Note down your heart beat per minute daily for ten days while seeing the girl.”
Now the data of heart beat/min  of the boys  after ten days was like this
 Day 1 2 3 4 5 6 7 8 9 10 Boy 1 98 96 92 94 95 89 79 73 92 75 Boy 2 96 88 86 82 89 90 79 75 82 78 Boy 3 78 76 74 75 77 79 76 78 79 80
After collecting the data the boys went  to the professor and show the data.
Professor calculated the averages of data of heartbeats of all three boys and find that
 Average heartbeat/minof all three boys Boy 1 Boy 2 Boy 3 88.30 84.50 77.20
Now professor said to first boy that  show the data to the girl and tell her that your average heart beat is highest among three boys so you  are the perfect life partner for the girl as your heart is beating more than other two boys
Boys went to the girl and first boy said very confidently  by showing the data , “Miss, here is the data of our  heartbeats for ten days whenever we saw  you our  hearts were beating more than the normal and also my average heartbeat  is  more than other two boys , So I   am the best person to get marry with you.”
Girl replied in the answer of the boy, “OK, Gentleman, but I would like to analyze all the  data by my own and then I will answer you that who will be best person to get marry with me. I will answer you in next three days at  three different places individually.”
Next  three days would going to be very crucial to all three boys as they don’t know who will get the opportunity to marry with the girl.
The girl analysis the whole data by own and found the result below
 Variable Day Mean Std. Dev. Coeff. Var. Min. Median Max. Skewness Boy1 10 88.30 9.17 10.38 73.00 92.00 98.00 -0.86 Boy2 10 84.50 6.43 7.61 75.00 84.00 96.00 0.26 Boy3 10 77.20 1.93 2.50 74.00 77.50 80.00 -0.24

Now on next day the girl meet the first boy and said , “ No doubt that your average heart beat is more than other two boys but Std. Dev. and coff. of var.  is very high  which is 9.17, and 10.38 respectively which shows that your love to me has very high variability and very low consistency also value of skewness -0.86 shows high negative asymmetry of data and the difference between  your minimum and maximum value of  heart beat is 25 this shows that sometime you will love me with high emotions and sometime  this shows neutral behavior to me , So in all in all the data of your heartbeat is not reliable and so I cannot marry with you, I am very sorry gentleman.”

Next day girl meet the  2nd boy and said, “ Your average heartbeat is also good but the Std. Dev and Coff. of Var.  are 6.43 and 7.61. No doubt both are less than in case of the first boy but still the variation of  data is quite high. It shows that your love to me also  has  high variability and low consistency. The value of skewness 0.26  shows that low  positive asymmetry of  data. The difference between your minimum and maximum value of heartbeat is 21 which means high difference of intensity of love towards me. Above all ,  your data  shows that your love is also not static to me, so gentleman I cannot go with you, Sorry.”

At last girl meet the third boy, who was looking very depressed as he had lowest average heartbeat. Girl said to the boy, “ Gentleman your heartbeat is 77.20 lowest among three but Std. Dev. and Coff. of Var. are 1.93 and 2.50 respectively which shows low variability and quite good consistency. Also the value of skewness is -0.24 is also the lowest value of asymmetry of data. The difference of  your minimum and maximum value of heartbeat is 6 which also lowest among three which means your love to me is quite static throughout the life even the intensity of love is low. Above all,  the data analysis shows you could be better life partner for me.

Then the Girl bent on her knees
To listen the answer of the girl the third boy filled with joy and  picked up the girl in his arms.
This way the girl chose the right partner for her using statistics.
From the above story we conclude that Statistics make us enough capable to take  right decisions at right time and in  right way not only in corporate life but also in our personal life.
