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 open doors to better loan terms, lower interest rates, and even affect the decision of potential employers. In this article, we will delve into the concept of credit scores, explore the given data, and calculate the median credit score of a group of individuals in Xavier's neighborhood.

What is a Credit Score?

A credit score is a three-digit number that represents an individual's credit history and financial behavior. It is calculated based on various factors, including payment history, credit utilization, length of credit history, and new credit inquiries. 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 for lenders.

Understanding Median Values

The median is the middle value of a dataset when it is arranged in ascending or descending order. It is a measure of central tendency that is used to describe the distribution of data. In the context of credit scores, the median value represents the middle score of a group of individuals. This is particularly useful when dealing with skewed data, as it provides a more accurate representation of the data distribution than the mean.

Given Data

Xavier has compiled the credit scores of people in his neighborhood into the following table:

Name	Credit Score
Alex	620
Ben	680
Charlie	720
David	780
Emily	820
Frank	840
George	860
Hannah	880
Isaac	900
Julia	920
Kevin	940
Laura	960
Michael	980
Nicole	1000
Olivia	1020
Patrick	1040
Quinn	1060
Rachel	1080
Samuel	1100
Thomas	1120
Ursula	1140
Victor	1160
William	1180
Xavier	1200

Calculating the Median Credit Score

To calculate the median credit score, we need to arrange the data in ascending order:

Name	Credit Score
Alex	620
Ben	680
Charlie	720
David	780
Emily	820
Frank	840
George	860
Hannah	880
Isaac	900
Julia	920
Kevin	940
Laura	960
Michael	980
Nicole	1000
Olivia	1020
Patrick	1040
Quinn	1060
Rachel	1080
Samuel	1100
Thomas	1120
Ursula	1140
Victor	1160
William	1180
Xavier	1200

Since there are 20 data points (an even number), the median will be the average of the 10th and 11th values. The 10th value is 920, and the 11th value is 940. Therefore, the median credit score is:

(920 + 940) / 2 = 930

Conclusion

In conclusion, the median credit score of the group of individuals in Xavier's neighborhood is 930. This value represents the middle score of the group and provides a more accurate representation of the data distribution than the mean. Understanding credit scores and median values is essential in making informed financial decisions and evaluating creditworthiness.
