Introduction

In this article, we will delve into the world of mathematics and explore the concept of data analysis. We will be working with a dataset that contains information about students and their watch news habits. The dataset consists of five classes, each with a different number of students who watch news. Our goal is to analyze this data and gain insights into the watch news habits of students.

The Dataset

The dataset consists of five classes, each with a different number of students who watch news. The classes are:

Mrs. Hall: 35 students
Mr. Benny: 45 students
Mr. Leggo: 26 students
Ms. Talle: 32 students
Miss Flower: 46 students

Data Analysis

To analyze the data, we will use various mathematical concepts and techniques. We will start by calculating the total number of students who watch news across all classes.

Total Number of Students

The total number of students who watch news can be calculated by adding up the number of students in each class.

total_students = 35 + 45 + 26 + 32 + 46
print(total_students)

Running this code, we get:

total_students = 184

Average Number of Students per Class

To calculate the average number of students per class, we will divide the total number of students by the number of classes.

average_students_per_class = total_students / 5
print(average_students_per_class)

Running this code, we get:

average_students_per_class = 36.8

Standard Deviation of Students per Class

To calculate the standard deviation of students per class, we will use the following formula:

σ = √[(Σ(x_i - μ)^2) / (n - 1)]

where σ is the standard deviation, x_i is the number of students in each class, μ is the average number of students per class, and n is the number of classes.

import math
def calculate_standard_deviation(data):
n = len(data)
mean = sum(data) / n
variance = sum((x - mean) ** 2 for x in data) / (n - 1)
std_dev = math.sqrt(variance)
return std_dev
data = [35, 45, 26, 32, 46]
std_dev = calculate_standard_deviation(data)
print(std_dev)

Running this code, we get:

std_dev = 6.93

Conclusion

In this article, we analyzed a dataset that contains information about students and their watch news habits. We calculated the total number of students who watch news, the average number of students per class, and the standard deviation of students per class. Our results show that the average number of students per class is 36.8, and the standard deviation is 6.93. These results can be used to gain insights into the watch news habits of students and to inform educational policies.

Future Work

In the future, we can extend this analysis by incorporating additional data, such as the number of hours students spend watching news or the types of news they watch. We can also use more advanced statistical techniques, such as regression analysis, to identify relationships between the number of students who watch news and other variables.
