Data Set: Data set: −8, −8, −9, 6, 1, 1, −9, −9, 6First, we need to determine how many times each number appears in the set.Frequency of −9: −80Frequency of −8: −82Frequency of 6: −82Frequency of 1: −82
Frequency Analysis: We found:Frequency of −9: 3Frequency of −8: 2Frequency of 6: 2Frequency of 1: 2Now, we need to identify which number(s) have the highest frequency.The number −9 has the highest frequency, occurring 3 times.
Identifying Highest Frequency: Since −9 has the highest frequency, it is the mode of the given data set.Mode: −9
