Course Introduction:The data visualization project uses the most popular chart engine ECharts to display all aspects of data that need to be presented in the e-commerce platform. Used to analyze the operation of e-commerce platforms in more detail in order to make correct decisions. The front-end of this project uses the Vue technology stack, the back-end uses the Koa2 framework, and the front-end and back-end data interaction uses WebSocket to ensure the real-time nature of the data. The project also supports theme switching to display cool chart effects. It also supports switching between large and small screens, ensuring that charts are presented on different screens.

Course Introduction:The arithmetic mean is the sum of a set of numbers divided by the number of numbers in the set. Basic properties of the arithmetic mean The average of n numbers x1, x2, . . .,xn is x. If each observation is increased by p, the mean of the new observations is (x+p). n numbers x1,x2,.. .,xn is x. If each observation decreases by p, the mean of the new observations is (x-p). n numbers x1,x2,.. .,xn is x. If each observation is multiplied by a nonzero number p, the mean of the new observations is px. The average number of n is x1,x2,. .,xn is x. If each observation is divided by a nonzero number p, the mean of the new observations is (x/p). Arithmetic mean formula type 1: Direct average of given number

Course Introduction:Python can use loops, built-in functions, and the numpy library to find the average. 1. Use a loop to iterate through the given list and add all the elements. Then, get the average by dividing by the length of the list. 2. Use the built-in function to add all the elements in the list. You can use the len() function in combination to get the length of the list, and then divide the two to get the average; 3. Use the numpy library, which provides many functions and tools for numerical calculations, etc.

Course Introduction:The average of the squares of natural numbers is calculated by adding all the squares of n natural numbers and then dividing by that number. The first two natural numbers in the example are 2.5, 12+22=5=>5/2=2.5. There are two methods of calculation in programming - Using loops Using formulas Calculating the average of squares of natural numbers using loops This logic works by finding the squares of all natural numbers. Find the square of each by looping from 1 to n and add to the sum variable. Then divide that sum by n. Program to calculate the sum of squares of natural numbers - sample code real-time demonstration #include<stdio.h>intmain(){ intn=2;
