Programs to try using arrays in R - Assignment 8

 Program List

 1.Student Performance Analysis

Marks of 5 students in 4 subjects over 3 semesters are stored in a three-dimensional array.

Write an R program to:

  • Find the total marks obtained by each student in each semester.
  • Find the average marks in each subject across all semesters.
  • Determine the student who scored the highest total marks.
  • Find the highest mark obtained in each semester.

2.Population Statistics

Population data of 5 cities over 10 years in 3 states are stored in an array.

Write an R program to:

  • Find the total population of each state.
  • Determine the city with the highest average population.
  • Find the year having the maximum population.
  • Calculate the average population of all cities.

3. Cricket Statistics

Runs scored by 11 players in 5 matches are stored in a two-dimensional array.

Write an R program to:

  • Find the total runs scored by each player.
  • Determine the highest run scorer.
  • Find the average score per match.
  • Display players who scored more than 50 runs in at least three matches.

4.Monthly Sales Analysis

Sales figures of 4 products over 12 months for 2 years are stored in a three-dimensional array.

Write an R program to:

  • Find the total annual sales for each year.
  • Find the total sales of each product.
  • Determine the product with the highest overall sales.
  • Find the month with the maximum sales.

5.Electricity Consumption Analysis

Monthly electricity consumption of 6 houses over 12 months is stored in an array.

Write an R program to:

  • Find the total annual consumption of each house.
  • Determine the month with maximum power consumption.
  • Find the house with the highest average consumption.
  • Calculate the overall average monthly consumption.

6.Store the marks of 100 students in 5 subjects over 2 semesters and determine the toppers of each semester.
