Imagine you're working with a dataset where the standard deviation is very small. How might this impact the effectiveness of z-score standardization?
- It will make the z-score standardization more effective
- It will not affect the z-score standardization
- The scaled values will be very large due to the small standard deviation
- The scaled values will be very small due to the small standard deviation
Z-score standardization scales data by subtracting the mean and dividing by the standard deviation. If the standard deviation is very small, the result of this division could be very large, leading to scaled values that are quite large.
