GinnyAnswer · Answer

List the credit scores: 634, 667, 644, 892, 627, 821, 857, 703, 654. 
 Count the frequency of each credit score. 
 Since no credit score appears more than once, there is no mode. 
 The mode is: There is no mode in this group ​ . 
 
 Explanation 
 
 Understand the problem We are given a set of credit scores and asked to find the mode. The mode is the value that appears most frequently in a data set. 
 
 List the data The credit scores are: 634, 667, 644, 892, 627, 821, 857, 703, 654. 
 
 Count frequencies Let's count the frequency of each credit score:

634 appears 1 time 
 667 appears 1 time 
 644 appears 1 time 
 892 appears 1 time 
 627 appears 1 time 
 821 appears 1 time 
 857 appears 1 time 
 703 appears 1 time 
 654 appears 1 time

Determine the mode Since no credit score appears more than once, there is no mode in this data set. 
 
 Final Answer Therefore, the mode of the credit scores in Will's department is 'There is no mode in this group'.

Examples 
 Understanding the mode is useful in many real-world scenarios. For example, a clothing store might track the sizes of clothes that customers buy most frequently. The mode of this data would help the store to stock up on the most popular sizes. Similarly, in education, identifying the mode of test scores can help teachers understand which scores are most common and adjust their teaching methods accordingly. In manufacturing, the mode of product defects can help identify the most common issues and improve quality control.

The mode of the credit scores in Will's department is determined by assessing the frequency of each score. Since all scores appear only once, there is no mode in this dataset. Therefore, the answer is 'There is no mode in this group.'
