Step1: Understand the concept of mean

The mean is the average value. In a histogram, the mean is influenced by the frequency and the mid - value of each class.

Step2: Analyze the frequencies

The class 174 - 181 has the highest frequency (17 students). The higher frequency class pulls the mean towards it.
The class 158 - 165 has a low frequency (6 students), 190 - 197 has a very low frequency (4 students), and 182 - 189 has a moderate frequency (11 students) compared to 174 - 181.
