The test results show how your student compares nationally to other students in the same grade level who took the same test at the same time of year (Fall, Midyear, or Spring) when the test was normed. Webb12 nov. 2024 · Normalization. Standardization. 1. Minimum and maximum value of features are used for scaling. Mean and standard deviation is used for scaling. 2. It is used when features are of different scales. It is used when we want to ensure zero mean and unit standard deviation. 3.
