How to implement Statistics functions in Numpy using Python?

-

              This is a branch of mathematics. It collects the data, analyses it and present it accordingly. It has many methods which is used to find sum, average, minimum , maximum and so on.

Let us implement the list of functions given below…..

  • Sum: to find the total of all elements.
  • Mean: it find the average value.
  • Median :it gives you the middle value after sorting.
  • Maximum :this function gives you maximum value of the array.
  • Minimum: it provides the minimum value of the array.
  • Standard deviation: it finds the standard deviation value.
  • Variance: it is the square of the standard deviation.
  • Product: it multiplies all elements.
  • Cumulative sum: it gives the running total.
  • Cumulative product: it finds the running product value.

Program to find values for all functions:

import numpy as np1

s_arr = np1.array([11,12,13,14,15,16])

s_sum= np1.sum(s_arr)

s_prod = np1.prod(s_arr)

s_mean = np1.mean(s_arr)

s_medi = np1.median(s_arr)

s_min = np1.min(s_arr)

s_max = np1.max(s_arr)

s_std = np1.std(s_arr)

s_var = np1.var(s_arr)

s_csum = np1.cumsum(s_arr)

s_psum = np1.cumprod(s_arr)

print("The sum of the array elements are:",s_sum)

print("The product of the array elements are:",s_prod)

print("The mean of the array elements are:",s_mean)

print("The median of the array elements are:",s_medi)

print("The minimum value in the array is:",s_min)

print("The maximum value in the array is:",s_max)

print("The standard deviation of the array elements are:",s_std)

print("The variance value is:",s_var)

print("The cumulative sum of the array elements are:",s_csum)

print("The cumulative product of the array elements are:",s_psum)

Output:

The sum of the array elements are: 81

The product of the array elements are: 5765760

The mean of the array elements are: 13.5

The median of the array elements are: 13.5

The minimum value in the array is: 11

The maximum value in the array is: 16

The standard deviation of the array elements are: 1.707825127659933

The variance value is: 2.9166666666666665

The cumulative sum of the array elements are: [11 23 36 50 65 81]

The cumulative product of the array elements are: [     11     132    1716   24024  360360 5765760]

This is the way of using statistics functions in Numpy using Python. Hope, you understood the concept. Keep Coding!!!!

XML  is    e X tensible M arkup L anguage which is used to create used defined tags.  It has Elements  ( <STUDENT>) Attributes (<STUDENT id="21it21">) To create a XML file, create three files 1 ->  XML file (used to declare the user defined tags) 2 ->  DTD file (used to define the user defined tags) 3 ->  HTML file(used to display the xml file as web page) create these three files using any editor like notepad.  Student.Xml <?xml version="1.0"?> <!DOCTYPE STUDENTS SYSTEM "E:\XML1\STUDENT.dtd"> <STUDENTS>  <STUDENT>  <STUDENTDATA>     <NAME> SUTHA </NAME>     <ID>  2007IT51 </ID>     <AGE> 20 </AGE>     <ADDRESS> 12, SATHY ROAD , GOBI </ADDRESS>   </STUDENTDATA> </STUDENT> </STUDENTS> Student.dtd <?xml version="1.0"?> <!ELEMENT STU...

Employee record management in C

-
               Let us create a employee record management in C. A employee record has name, id and salary. The operations are adding the details, search an employee, delete a record and display the employee records. Program implementation: #include <stdio.h> #include <stdlib.h> #include <string.h> #define MAX 100 struct Employee {     int e_id;     char e_name[50];     float e_salary; }; struct Employee emp[MAX]; int count = 0; void addEmployee() {     printf("\nEnter the Employee id: ");     scanf("%d", &emp[count].e_id);     printf("Enter the Employee Name: ");     scanf(" %[^\n]", emp[count].e_name);     printf("Enter the salary: ");     scanf("%f", &emp[count].e_salary);     count++;     printf("Employee details ar...

Datatypes and Variables in java script

-
Image
Datatypes are used to hold the values of variables. JavaScript has two types of datatypes. ·        Primitive data types ·        Non-primitive data types Java script is a dynamic type. It is not important to mention the datatype earlier. Use “var” for variable. Primitive data types: Javascript has 5 primitive data types. They are listed below. Boolean : it represents zero or one value. Number : it represents numbers. String :it represents sequence of characters. Null : it represents no value. Undefined: if you want to define the value later, use this data type. Non- primitive data types: Javascript has 3 different types of non-primitive data types. They are given below. Array : It has a list of similar values Object : it is a instance of a class. Regexp : It is for Regular Expressions.   Variables:   Variables are so important for any language. It specifies the value. In javascri...
