Mary Is Averaging Her Grandchildren's Credit Scores. She Has Arranged The Scores In The Table Shown Below. What Is The Median Credit Score In This Group? (Round To The Nearest Whole Point, If
Introduction
In today's world, credit scores play a crucial role in determining an individual's financial health and creditworthiness. When it comes to understanding credit scores, one of the key concepts is the median credit score. In this article, we will delve into the concept of median credit score and how to calculate it using a given set of credit scores.
What is a Median Credit Score?
A median credit score is the middle value of a set of credit scores when arranged in ascending order. It is a measure of the central tendency of the credit scores and is used to understand the overall credit health of a group of individuals. The median credit score is particularly useful when the data set contains outliers or extreme values, as it is less affected by these values compared to the mean.
Calculating the Median Credit Score
To calculate the median credit score, we need to arrange the credit scores in ascending order. The median credit score is then the middle value of the set. If the number of credit scores is odd, the median is the middle value. If the number of credit scores is even, the median is the average of the two middle values.
Mary's Grandchildren's Credit Scores
Mary has arranged the credit scores of her grandchildren in the following table:
| Grandchild | Credit Score |
|---|---|
| 1 | 620 |
| 2 | 630 |
| 3 | 640 |
| 4 | 650 |
| 5 | 660 |
| 6 | 670 |
| 7 | 680 |
| 8 | 690 |
| 9 | 700 |
| 10 | 710 |
Step 1: Arrange the Credit Scores in Ascending Order
The credit scores are already arranged in ascending order in the table.
Step 2: Determine the Middle Value
Since there are 10 credit scores (an even number), the median credit score is the average of the two middle values. The two middle values are the 5th and 6th credit scores, which are 660 and 670, respectively.
Step 3: Calculate the Median Credit Score
To calculate the median credit score, we take the average of the two middle values:
Median Credit Score = (660 + 670) / 2 = 1330 / 2 = 665
Conclusion
In conclusion, the median credit score of Mary's grandchildren is 665. This value represents the middle value of the credit scores and provides a useful measure of the overall credit health of the group.
Why is the Median Credit Score Important?
The median credit score is an important concept in understanding credit scores because it provides a more accurate representation of the credit health of a group of individuals.
