Introduction

In today's world, credit scores play a crucial role in determining an individual's financial health and creditworthiness. A good credit score can help individuals secure loans and credit cards at favorable interest rates, while a poor credit score can lead to higher interest rates and even loan rejections. In this article, we will explore the concept of credit scores, discuss the importance of understanding credit scores, and calculate the mean credit score of a group of friends based on an anonymous survey conducted by Sophie.

What are Credit Scores?

A credit score is a three-digit number that represents an individual's creditworthiness. It is calculated based on their credit history, payment history, credit utilization, and other factors. The most widely used credit score is the FICO score, which ranges from 300 to 850. A higher credit score indicates a better credit history and a lower risk of default.

Importance of Understanding Credit Scores

Understanding credit scores is essential for individuals to manage their finances effectively. A good credit score can help individuals:

Secure loans and credit cards at favorable interest rates
Qualify for lower interest rates on loans and credit cards
Get approved for credit cards and loans with higher credit limits
Enjoy better loan terms and conditions

Calculating the Mean Credit Score

To calculate the mean credit score, we need to add up all the credit scores and divide by the number of scores. Let's assume the credit scores of Sophie's friends are listed in the table below:

Name	Credit Score
John	620
Emily	680
Michael	720
Sarah	780
David	840
Olivia	900
Ava	940
Ethan	980
Liam	1020
Isabella	1060

Step 1: Add up all the credit scores

To calculate the mean credit score, we need to add up all the credit scores. Let's do the math:

620 + 680 = 1300 1300 + 720 = 2020 2020 + 780 = 2800 2800 + 840 = 3640 3640 + 900 = 4540 4540 + 940 = 5480 5480 + 980 = 6460 6460 + 1020 = 7480 7480 + 1060 = 8540

The sum of all the credit scores is 8540.

Step 2: Count the number of credit scores

There are 10 credit scores in the table.

Step 3: Calculate the mean credit score

To calculate the mean credit score, we need to divide the sum of all the credit scores by the number of credit scores:

8540 ÷ 10 = 854

Conclusion

In this article, we discussed the concept of credit scores, their importance, and how to calculate the mean credit score. We used an anonymous survey conducted by Sophie to calculate the mean credit score of her friends. The mean credit score of Sophie's friends is 854. This indicates that Sophie's friends have a good credit history and are likely to secure loans and credit cards at favorable interest rates.
