Assignment
1. Suppose you have the following noisy data: 33, 23, 40, 22, 46, 33, 52, 27, 43, 38, 28
Smooth the data above by:
a) Bin Means with bins of size 4.
b) Bin Boundaries with bins of size 4.
2. Use Min/Max normalization to represent the hypothetical data below in the scale
28 - 35 - 62 - 69 - 73
3. By using decimal scaling, normalize the values of 8, 66, 171 that falls between 1 and 999.
